Abstract
Description
본 발명은 수소수 생산용 전극 및 이의 제조 방법에 관한 것으로, 더욱 상세하게는 더 나은 전기분해 특성을 가지는 수소수 생성용 전기분해 전극을 제작할 수 있도록 구현한 수소수 생산용 전극 및 이의 제조 방법에 관한 것이다.The present invention relates to an electrode for producing hydrogen water and a method for manufacturing the same, and more specifically, to an electrode for producing hydrogen water and a method for manufacturing the same, which are implemented to produce an electrolysis electrode for generating hydrogen water having better electrolysis properties. It is about.
현재 국외에서 의학 분야에 수소에 대한 많은 연구가 진행되고 있으며, 이는 활성산소를 제거하는 치료법 중 효과적인 방법으로 연구되고 있다.Currently, many studies on hydrogen have been conducted in the medical field abroad, and this is being studied as an effective method among treatments for removing free radicals.
Nature Medicine(2007)을 비롯한 다양한 저명한 해외 논문지에서 500여 건 이상의 논물을 통해 제시되고 있는 것처럼, 수소는 활성 산소를 제거하는데, 특히 가장 반응성이 높은 하이드록실라디칼과 선택적으로 반응하여 물로 전환되고, 이러한 수소를 이용한 헬스 케어는 심혈관질환, 악성신생물, 만성호흡기질활, 뇌혈관질한, 알츠하이머 질환, 인믈루엔자, 폐렴, 당뇨 등 다양한 질환에 사용하는 연구가 진행되고 있다.Hydrogen removes free radicals, as suggested by more than 500 rice fields in various prestigious foreign papers, including Nature Medicine (2007), particularly converts to water by selectively reacting with the most reactive hydroxyl radicals. Health care using hydrogen is being used for various diseases such as cardiovascular disease, malignant neoplasm, chronic respiratory activity, cerebrovascular disease, Alzheimer's disease, influenza, pneumonia, and diabetes.
일본에서는 이러한 수소의 건강에 대한 역할로 인해, 수소수음료, 수소캡슐, 수소수정수기, 수소발생스틱, 수소 입욕제, 수소 팩 등등 많은 산업이 발달되었고, 이를 통해 건강을 회복하고, 실생활에서도 많은 음용이 이루어지고 있다.Due to the role of hydrogen in Japan, many industries such as hydrogen beverages, hydrogen capsules, hydrogen water purifiers, hydrogen generating sticks, hydrogen bathing agents, hydrogen packs, etc. have been developed, thereby restoring health and drinking a lot in real life. This is being done.
국내에서도 여러 피부과에서 피부 노화에 효과가 있는 수소 토닝, 수소 베일과 같은 수소치료가 진행되고 있다.Hydrogen treatments such as hydrogen toning and hydrogen veil, which are effective in aging the skin, are also being conducted in various dermatologists in Korea.

도 1은 본 발명의 일 실시예에 따른 수소수 생산용 전극 제조 방법을 설명하는 순서도이다.1 is a flowchart illustrating a method of manufacturing an electrode for producing hydrogen water according to an embodiment of the present invention.
본 발명은 전기 도금 및 PVD 증착법인 E-beam evaporator를 번갈아 가며 공정하여 수소수 생산용 전극을 제조하기 위한 방법으로서, 도 1을 참조하면, 본 발명의 일 실시예에 따른 수소수 생산용 전극 제조 방법은, 우선, Ti 기판(100)(Ti substrate)의 상측에 전기도금 방식을 이용하여 제1막(200)을 형성시킨다(S110).The present invention is a method for producing an electrode for producing hydrogen water by alternately processing an E-beam evaporator, which is an electroplating and PVD deposition method. Referring to FIG. 1, an electrode for producing hydrogen water according to an embodiment of the present invention First, the first film 200 is formed by using an electroplating method on the upper side of the Ti substrate 100 (S110 ).
일 실시예에서, 제1막(200)을 형성시키는 단계(S110)는, 망간(Mn), 철(Fe), 구리(Cu), 니켈(Ni) 및 루테늄(Ru) 중 적어도 하나의 금속을 전기도금하여 제1막(200)을 형성시킬 수 있다.In one embodiment, the step (S110) of forming the first film 200 includes at least one metal of manganese (Mn), iron (Fe), copper (Cu), nickel (Ni), and ruthenium (Ru). The first film 200 may be formed by electroplating.
즉, 본 발명의 증착 기판으로는 상용 전극에 많이 사용되는 Ti 기판을 이용하며, Ti 기판의 클리닝 공정 후 전기도금 방식(electroplating, 電氣鍍金)을 이용하여 망간(Mn), 철(Fe), 구리(Cu), 니켈(Ni) 또는 루테늄(Ru) 등과 같이 저가의 비귀금속을 일정 두께의 제1막(200)을 형성하게 된다.That is, as the deposition substrate of the present invention, a Ti substrate commonly used for commercial electrodes is used, and after the cleaning process of the Ti substrate, manganese (Mn), iron (Fe), copper is used by using an electroplating method (Cu), nickel (Ni) or ruthenium (Ru), such as a low-cost non-precious metal to form a first film 200 of a certain thickness.
상술한 단계 S110에서 제1막(200)의 형성이 완료되면, E-Beam 진공증착법(Electronic-Beam Evaporator, Electronic-Beam을 이용하여 증발원을 가열시켜 증착시키는 방법으로서, 가판을 만들려는 물질의 용융점이 넓은 경에 많이 사용됨)을 이용하여 제1막(200)의 상측에 제2막(300)을 증착시킨다(S120).When the formation of the first film 200 is completed in the above-described step S110, a method of heating and depositing an evaporation source using an E-Beam Evaporator (Electronic-Beam) is a melting point of a material to be produced. The second film 300 is deposited on the upper side of the first film 200 by using a large diameter (used for this wide diameter) (S120).
일 실시예에서, 제2막(300)을 증착시키는 단계(S120)는, 비백금계 촉매재료인 팔라듐(Pd)을 이용하여 nm 단위의 얇은 박막인 제2막(300)을 증착시킬 수 있다.In one embodiment, the step of depositing the second film 300 (S120) may deposit the second thin film 300 of nm thin film using palladium (Pd), which is a non-platinum catalyst material.
제1막(200)을 형성시키는 단계(S110)와 제2막(300)을 증착시키는 단계(S120)를 교대로 반복 수행하여 Ti 기판(100)의 상측에 다층 구조가 형성된 다층구조 전극(400)을 제조한다(S130).The
상술한 단계 S130에서는, 상술한 단계 S110와 S120를 교대로 수회 반복하여 저가 금속 막과 촉매재료 박막을 다층구조로 쌓아 금속의 계면구조 형성을 통해 효율을 증대시키게 된다.In the above-described step S130, the above-described steps S110 and S120 are alternately repeated several times to increase the efficiency through the formation of the interfacial structure of the metal by stacking the low-cost metal film and the catalyst material thin film in a multi-layer structure.
같은 두께로 물질을 증착시켰을 때, 단순히 두 개의 층으로 물질을 증착시키는 것에 비하여, 도 2에 도시된 바와 같은 구조로 얇은 막의 다층구조를 형성하는 다층구조 전극(400)을 통해 금속 간의 계면을 형성하면 계면 사이에서의 특성에 의해 더 높은 효율을 얻을 수 있다.When depositing a material with the same thickness, an interface between metals is formed through a
다만, 도 2에는 제1막(200)과 제2막(300)이 각각 세 차례 교대(즉, 세 개의 제1막(200-1 내지 200-3)과 세 개의 제2막(300-1 내지 300-3)로 형성된 다층구조 전극(400)에 관하여 도시되었으나, 제1막(200)과 제2막(300)의 교차 적층은 세 차례에 한정되는 것은 아니며, 사용자의 필요에 따라 보다 많게 또는 보다 적게 형성되어도 무방하다.However, in FIG. 2, the first film 200 and the second film 300 alternate three times (ie, three first films 200-1 to 200-3) and three second films 300-1. Although it is illustrated with respect to the
상술한 단계 S130에 의해 제작된 다층구조 전극(400)에 부동화 피막(passivation film, 철, 코발트, 니켈 등의 양극 산화막처럼 보통의 화학 반응성을 상실한 상태의 금속 산화 피막)인 제1피막(500)을 만들어준다(S140).The
여기서, 제1피막(500)을 만들어주는 단계(S140)에서의 부동화 피막 물질로서 메탄올 베이스의 PVB(Poly Vinyl Butyral, 폴리바이닐부티랄) 용액을 이용할 수 있으며, 다층구조 전극(400)에 PVB 용액을 dip coating 또는 drop-casting & spin-coating을 이용하여 제1피막(500)을 만들어줄 수 있다.Here, a methanol-based PVB (Poly Vinyl Butyral, polyvinyl butyral) solution may be used as the passivation film material in the step (S140) of making the
상술한 단계 S140에서 만들어준 제1피막(500)이 부동화 피막으로 작용할 수 있도록 제1피막(500)이 만들어진 다층구조 전극(400)에 제2피막(600)을 만들어준다(S150).The
여기서, 제2피막(600)을 만들어주는 단계(S150)는, 극초순수(Deionized Water)를 이용하여 제2피막(600)을 만들어줄 수 있으며, 극초순수(Deionized Water)를 dip coating 또는 drop-casting & spin-coating을 이용하여 제1피막(500)을 만들어줌으로써, 상술한 단계 S140에서 만들어준 제1피막(500), 즉, PVB막이 전극의 안정성을 늘려주는 부동화 피막으로 작용할 수 있도록 한다.Here, in the step (S150) of making the
상술한 바와 같은 단계를 가지는 수소수 생산용 전극 제조 방법은, 제1막(200)을 형성시키는 단계(S110) 이전에, 전극의 수소분해 성능을 향상시키고 정밀도를 향상시키기 위한 Ti 기판(100)을 클리닝하는 공정을 더 포함할 수 있다(설명의 편의상 도면에는 도시하지 않음).The method of manufacturing an electrode for producing hydrogen water having the above-described steps, prior to the step of forming the first film 200 (S110), improves the hydrogen decomposition performance of the electrode and improves the precision of the
상술한 바와 같은 단계를 가지는 수소수 생산용 전극 제조 방법은, 전기도금 방식을 이용하여 값싼 Ni과 같은 금속으로 형성되는 비교적 두꺼운 막과 E-beam evaporator를 이용함으로써, 귀금속 또는 전기 금속 촉매 합금이 쉽게 되지 않아 분해 촉매로서의 사용이 용이하지 않은 금속도 계면 효과를 이용하여 보다 나은 전기분해 특정을 가지도록 할 수 있다.The electrode manufacturing method for producing hydrogen water having the steps as described above, by using a relatively thick film and an e-beam evaporator formed of a cheap metal such as Ni using an electroplating method, the noble metal or electrometal catalyst alloy is easily Metals that are not easy to use as a decomposition catalyst can also have better electrolysis characteristics by using an interfacial effect.
도 3은 PVB 부동화 피막 적용에 따른 안정화 테스트를 비교한 그래프이다.3 is a graph comparing the stabilization test according to the application of the PVB passivation film.
도 3은, 1X2cm 크기로 만들어진 전극에 부동화 피막의 유무에 따라 5V 전압을 12시간 동안 일정하게 가하며 전류 변화를 측정한 것이다.FIG. 3 shows a change in current by applying a 5V voltage for 12 hours depending on the presence or absence of a passivation film on an electrode made of 1X2cm.
PVB 부동화 피막 적용 전에는 시간이 지남에 따라 일정하게 전류가 감소하고 15% 정도의 전도도 감소를 보이지만, 본 발명에 따른 PVB 부동화 피막 적용 시에는 전도도가 거의 일정하게 유지됨을 확인할 수 있다.Prior to the application of the PVB passivation film, the current decreases steadily over time and shows a decrease in conductivity of about 15%, but it can be seen that when the PVB passivation film according to the present invention is applied, the conductivity remains almost constant.
