도 1은 본 발명의 일 실시예에 따른 전도성 및 축열성을 가지는 직물의 제조방법을 나타낸 흐름도로써, 본 발명은 VGCNF 및 PVDF-HFP 복합용액을 제조하는 단계(P100) 및 상기 제조된 VGCNF 및 PVDF-HFP 복합용액을 전기방사하여 나노섬유 웹 상태로 직물에 나노 코팅하는 단계(P200)를 포함하여 구성된다.

상기 VGCNF 및 PVDF-HFP 복합용액을 제조하는 단계(P100)는, 직물에 전도성 및 축열성을 부여하기 위한 VGCNF 및 PVDF-HFP 복합용액을 제조하는 단계로써, 아세톤 100 중량부에 대하여 PVDF-HFP 칩 10 ~ 15 중량부를 85 ~ 95분간 교반하여 PVDF-HFP 용액을 제조한 후, 상기 제조된 PVDF-HFP 용액 100 중량부에 대하여, VGCNF 10 ~ 20 중량부를 첨가하여 85 ~ 95분간 교반하고, 95 ~ 100W, 40 ~ 45KHz의 조건에서 20 ~ 40시간 동안 초음파 처리한 후, 15 ~ 20℃에서 1 ~ 7일간 보관하여 VGCNF 및 PVDF-HFP 복합용액을 제조한다.
The preparing of the VGCNF and PVDF-HFP composite solution (P100) is a step of preparing the VGCNF and PVDF-HFP composite solution for imparting conductivity and heat storage property to the fabric, and the PVDF-HFP chip based on 100 parts by weight of acetone. After stirring 10 to 15 parts by weight for 85 to 95 minutes to prepare a PVDF-HFP solution, 10 to 20 parts by weight of VGCNF was added to 100 parts by weight of the prepared PVDF-HFP solution, stirred for 85 to 95 minutes, 95 ~ After sonication for 20 to 40 hours at 100W, 40 ~ 45KHz condition, and then stored for 1 to 7 days at 15 ~ 20 ℃ to prepare a VGCNF and PVDF-HFP composite solution.
이때, 사용되는 PVDF-HFP는 폴리비닐리덴플루오라이드(polyvinlylidenefluoride)와 헥사메틸렌디아민(hexamethylenediamine)의 공중합체로써 직물에 전도성 및 축열성을 부여하고자 첨가되는 것으로, 아세톤 100 중량부에 대하여, 10 ~ 15 중량부가 사용되는데, 상기 PVDF-HFP의 사용량이 10 중량부 미만일 경우, 전기방사 시 코팅막의 형태가 형성되지 못할 우려가 있으며, 15 중량부를 초과할 경우, 전기방사 시 나노웹상으로 형성되지 못할 우려가 있다.
In this case, PVDF-HFP is used as a copolymer of polyvinlylidenefluoride and hexamethylenediamine and is added to impart conductivity and heat storage property to the fabric. Although parts by weight are used, when the amount of PVDF-HFP is less than 10 parts by weight, there is a risk that the coating film may not be formed during electrospinning, and when it exceeds 15 parts by weight, there is a concern that the PVDF-HFP may not be formed on a nanoweb during electrospinning. have.
아울러, 상기 VGCNF는 고온하에서 분해된 기체상의 탄화수소에 의해서도 생성된 증기성장형 탄소나노섬유(vapor growth carbon nano fiber)로써 직물에 전도성 및 축열성을 부여하고자 첨가되는 것으로, 상기 PVDF-HFP 용액 100 중량부에 대하여, 10 ~ 20 중량부가 사용되는데, 상기 VGCNF의 사용량이 10 중량부 미만일 경우, 전도성이 낮게 나타날 우려가 있으며, 20 중량부를 초과할 경우, 전기방사 시 나노웹상으로 코팅되지 못할 우려가 있다.
In addition, the VGCNF is a vapor growth carbon nanofiber produced by gaseous hydrocarbons decomposed under high temperature, and is added to impart conductivity and heat storage property to the fabric. 100 parts by weight of the PVDF-HFP solution With respect to, 10 to 20 parts by weight is used, when the amount of the VGCNF is less than 10 parts by weight, there is a fear that the conductivity is low, if the amount exceeds 20 parts by weight, there is a fear that the coating on the nanoweb during electrospinning.
한편, 상기 단계(P100)의 각 조건(교반 및 초음파 처리 조건 등)이 상기 범위를 벗어날 경우, VGCNF의 분산성이 저하되어 VGCNF 및 PVDF-HFP 복합용액이 제대로 제조되지 않거나 또는 충분한 전도성 및 축열성을 발현시키지 못할 우려가 있다.
On the other hand, if each condition (stirring and sonication conditions, etc.) of the step (P100) is out of the above range, the dispersibility of the VGCNF is lowered, the VGCNF and PVDF-HFP composite solution is not properly prepared or sufficient conductivity and heat storage property There is a risk of not expressing.
상기 VGCNF 및 PVDF-HFP 복합용액을 전기방사하여 나노섬유 웹 상태로 직물에 나노 코팅하는 단계(P200)는, VGCNF 및 PVDF-HFP 복합용액을 직물에 나노 코팅하여 직물에 우수한 전도성 및 축열성이 부여되면서도 직물의 물성은 그대로 유지할 수 있도록 하는 단계로써, 양전하 직류 전압 35 ~ 45kV까지 공급할 수 있는 고전압 직류 공급기에 23 ~ 26G의 전기방사 바늘을 연결한 후, 12 ~ 21kV 전압을 상기 VGCNF 및 PVDF-HFP 복합용액에 공급하여 전기방사하되, 방사 거리는 10 ~ 15cm, 용액의 토출속도는 3 ~ 8ml/h로 15 ~ 20℃에서 전기방사하여 이를 나노섬유 웹 상태로 직물에 나노 코팅한다.
Nano-coating the fabric in a nanofiber web state by electrospinning the VGCNF and PVDF-HFP composite solution (P200), by nano-coating the VGCNF and PVDF-HFP composite solution on the fabric to give excellent conductivity and heat storage property to the fabric. While maintaining the physical properties of the fabric as it is, after connecting the electrospinning needle of 23 ~ 26G to a high voltage DC supply capable of supplying a positive charge DC voltage of 35 ~ 45kV, 12 ~ 21kV voltage is applied to the VGCNF and PVDF-HFP Electrospinning is supplied to the composite solution, the spinning distance is 10 ~ 15cm, the discharge rate of the solution is 3 ~ 8ml / h and electrospinning at 15 ~ 20 ℃ and nano-coated on the fabric in the state of a nanofiber web.
이때, 상기 단계(P200)의 각조건(전압, 바늘종류, 방사거리, 토출속도, 온도 등)이 상기 범위를 벗어날 경우, VGCNF 및 PVDF-HFP 복합용액이 제대로 전기방사되지 않거나 또는 나노섬유 웹의 형태로 코팅되지 못할 우려가 있다.
At this time, if each condition (voltage, needle type, spinning distance, discharge speed, temperature, etc.) of the step (P200) is out of the above range, the VGCNF and PVDF-HFP composite solution is not properly electrospun or nanofiber web There is a fear that the coating may not be in the form.
한편, 상기 "나노섬유 웹(nanofiber web)"이란, 굵기가 나노미터(nm) 정도의 초극세사로 만든 섬유가 불규칙적으로 연결된 망(web)의 형태를 이루는 것을 의미하며, "나노섬유 웹 상태로 직물에 나노 코팅"된다는 것은, 상기와 같은 나노섬유 웹이 직물에 코팅됨을 의미한다.
On the other hand, the "nanofiber web" means that the fibers made of ultra-fine fibers having a thickness of about nanometers (nm) forms an irregularly connected web (web) in the form of "nanofiber web state Nanocoated "means that the nanofiber web is coated on a fabric.

After stirring 10 parts by weight or 15 parts by weight for 90 minutes to prepare a PVDF-HFP solution, with respect to 100 parts by weight of the prepared PVDF-HFP solution, 16 parts by weight of VGCNF (Pyrograf III Co. Ltd) was added and stirred for 90 minutes. Ultrasonic treatment (Brason 3510R-DTH, USA) for 24 hours at 100W, 42KHz, and then stored at 20 ℃ for 7 days to prepare a composite solution of VGCNF and PVDF-HFP (P100), to supply a positive charge DC voltage of 40kV After connecting a 23G electrospinning needle to a high voltage DC power supply (CPS-40K03, Chungpa EMT), supply a 12, 15, 18 or 21kV voltage to the VGCNF and PVDF-HFP composite solution to electrospin, but the radiation distance is 12cm , The discharge rate of the solution was electrospun at 20 ℃ at 5ml / h and nano-coated (P200) on the cotton or nylon fabric in a nanofiber web state to prepare a fabric having conductivity and heat storage properties, each Example and Comparative Example Specific conditions according to [Table 1] below Indicated.
2. 전도성 및 축열성을 가지는 직물의 평가
2. Evaluation of fabric having conductivity and heat storage
(1) 표면특성(1) Surface properties
상기 각 실시예 및 비교예에 따른 직물의 표면특성을 주사현미경(FE-SEM, JSM-35CF, Jeol, Japan)을 이용하여 관찰하였으며, 그 결과는 도 2a 및 도 2b에 나타내었다.
Surface characteristics of the fabrics according to the above Examples and Comparative Examples were observed using a scanning microscope (FE-SEM, JSM-35CF, Jeol, Japan), the results are shown in Figures 2a and 2b.
(2) 축열성(2) heat storage
축열성 분석은 37℃에서 10분 가열 후, 20초 경과 후에 적외선 열화상 측정장치(TVS-2000MK2 Serie, Nippon Avionivs Co., Ltd)를 이용하여 일정한 거리에서 상기 각 실시예 및 비교예에 따른 직물의 표면온도를 측정하였으며, 그 결과는 도 3에 나타내었다.
Thermal storage analysis is 10 minutes after heating at 37 ℃, 20 seconds after the infrared thermography (TVS-2000MK2 Serie, Nippon Avionivs Co., Ltd) using a fabric according to each of the above Examples and Comparative Examples at a constant distance The surface temperature of was measured, and the results are shown in FIG.
우선, 도 2a 및 2b에서와 같이, 전기방사 시, 비교예 1 ~ 8에서와 같이 인가전압이 12 또는 15kV의 낮은 인가전압으로 코팅한 경우 구슬달린 나노섬유의 웹 형태로 코팅된 것으로 확인하였다. 하지만, 실시예1 ~ 8에서와 같이, 인가전압이 18V이상 증가함에 따라 나노섬유 사이에 있는 구슬의 형태는 작아지고, 나노섬유는 더 가는 형태를 보이고 있었다. 특히 실시예 3,4 및 7, 8과 같이 21kV 전압을 걸어준 경우 균일한 나노웹 상태로 코팅된 것을 확인할 수 있었다.
First, as shown in Figures 2a and 2b, during the electrospinning, when the applied voltage is coated with a low applied voltage of 12 or 15kV as in Comparative Examples 1 to 8 it was confirmed that the coating in the form of a web of beaded nanofibers. However, as in Examples 1 to 8, as the applied voltage increased by more than 18V, the shape of the beads between the nanofibers became smaller, and the nanofibers showed a thinner shape. In particular, when the 21kV voltage was applied as in Examples 3, 4 and 7, 8 it was confirmed that the coating in a uniform nanoweb state.
아울러, 도 3에 도시된 바와 같이, 코팅하지 않은 직물의 경우, 면은 약 28℃, 나일론은 약 31℃에서 나타났으며, 직물의 종류에 관계없이 인가전압이 증가함에 따라 직물에 나노섬유 웹 코팅을 행한 경우, 표면온도는 증가하는 경향을 보였다. 특히, 15 중량부의 PVDF-HFP를 사용한 경우, 면직물의 표면온도는 33℃ 범위에서 나타났다. 즉, 인가전압 및 PVDF-HFP 용액의 농도에 따라 직물에 나노섬유 웹상의 코팅된 모폴로지의 변화에 따라 축열성에 영향을 미치는 것으로 볼 수 있으며, 이는 나노섬유 웹 형성시 열전도율이 낮은 공극이 형성되어 축열성이 증가하는 것으로 볼 수 있다.
In addition, as shown in Figure 3, in the case of the uncoated fabric, cotton appeared at about 28 ℃, nylon at about 31 ℃, the nanofiber web on the fabric as the applied voltage increases regardless of the type of fabric In the case of coating, the surface temperature tended to increase. In particular, when 15 parts by weight of PVDF-HFP was used, the surface temperature of the cotton fabric was in the range of 33 ° C. In other words, depending on the applied voltage and the concentration of PVDF-HFP solution, it can be seen that the heat storage property is affected by the change of the coated morphology on the nanofiber web on the fabric. It can be seen that the recessiveness is increased.
즉, 인가전압이 증가함에 따라 구슬 상에서 나노섬유 웹 상으로 코팅이 가능하였고, 인가전압이 증가할수록, 복합용액의 농도가 클수록 축열 특성이 우수해지는 것을 알 수 있다.
That is, it was possible to coat the nanofiber web on the beads as the applied voltage was increased, and as the applied voltage was increased, the heat storage characteristics were improved as the concentration of the composite solution was increased.
