Description

亲水性聚氨酯纳米纤维及其制备方法
技术领域
本发明涉及通过同轴电纺丝法制备聚氨酯/水溶性高分子共混纳米纤维之后将水溶性高分子溶解于水来去除，从而制备亲水性得到提高的聚氨酯纳米纤维的方法。
背景技术
电纺丝为主要将高分子溶解于溶液或直接溶化来制备具有数μm至数nm的直接的纤维的方法。相比于微单位的纤维，由电纺丝制备的纳米纤维的比表面积很大，不仅具有小气孔，还可自由调节气孔的大小，具有强的表面吸附性、对于物质的选择性透射性。而且，具有可对互不相同的材质进行复合化的许多优点。并且，纳米纤维的直径越小，相对于体积的表面积比率非常宽。宽的表面积不仅可以充分地营造湿润状态，而且这种结构具有与细胞底物的结构类似的三维结构，因此，可容易向伤患部位放射药物并可有效地伤口再生。通过电纺丝制备的纳米纤维试图通过过滤器材质、纤维材质、第二次电用电极材质、组织工学用支撑体、能源存储材质、纤维强化纳米复合材料、传感器用纤维、电子光学用纤维材质等几乎所有产业的各种利用。
聚氨酯(polyurethane，聚氨酯)通过聚异氰酸酯(-NCO)与多元醇(-OH)的反应生成，由于只有氨基甲酸乙酯具有的卓越的物性，应用于各种用途，从而用于鞋、沙发、床、汽车、冰箱、建筑材料、地板材料、田径跑道等日常生活中经常见到的产品的制备。并且，其应用还向用于处理有机性废弃物的生物过滤器、血液及血浆过滤器及润湿性敷料等环保及医学功能性材质扩大。
但是，当疏水性高分子材质适用于水处理过滤器或血液过滤器等时，通过各种有机化合物或蛋白质或微生物等化学或生物成分的吸附的污染及堵住现象成为问题，为防止所述现象，高分子过滤器的亲水性提高作为核心技术日益凸显。
聚氨酯也以进行电纺丝而获取的纳米纤维的形态试图应用于各种过滤器，但是，具有疏水性引起的类似问题，尤其，相比于常规过滤器用膜，纳米纤维具有相对更微细的孔隙，因此，堵住现象成为更严重的问题。并且，聚氨酯以多孔性泡沫(foam)形态制备来以代表性的润湿性敷料产品化并使用，在由纳米纤维制备的情况下，相比于泡沫，疏水性纳米网表面内的水分吸收显著下降，因此，难以期待润湿性创伤治愈效果。因此，为了使聚氨酯以纳米纤维的形态适用于创伤覆盖材料，必须改善聚氨酯纳米纤维的亲水性。
为了改善疏水性高分子结构体的亲水性，通常适用通过等离子处理的表面的亲水性基的导入、亲水性物质的涂敷及共混物等的方法。但是，等离子处理的亲水性提高效果甚微，在为了提高亲水性而使处理条件苛刻的情况下，具有机械物性降低的缺点。并且，在将亲水性高分子等涂敷于纳米网等的纳米纤维结构体的表面的情况下，产生气孔被堵住的现象，作为过滤器的用途展开将受限。尤其，包含大部分的聚氨酯的大部分的疏水性高分子与亲水性高分子没有相容性，混合时产生沉淀或其他相分离现象，从而形成不均匀的溶液，因此，实际上不可能电纺丝2种高分子的混合溶液来制备均匀的纳米纤维。
本发明人在为了解决如上所述的现有技术的问题并克服疏水性聚氨酯纳米纤维的问题而对聚氨酯的亲水性改善方法进行研究的过程中，发现在将不会共混的亲水性高分子和疏水性聚氨酯利用同轴电纺丝法制备纳米纤维的情况下，可制备亲水性高分子和聚氨酯共混的纳米纤维，进而，作为预料之外的结果，将所述共混纳米纤维内的亲水性高分子成分溶解于水而去除来制备的聚氨酯纳米纤维具有更优秀的亲水性，从而完成了本发明。
发明内容
(一)要解决的技术问题
本发明的目的在于，提供如下的聚氨酯纳米纤维的制备方法：将没有相容性的水溶性高分子和疏水性聚氨酯利用同轴电纺丝制备水溶性高分子/聚氨酯共混纳米纤维之后，将共混纳米纤维内的水溶性高分子溶解于水来去除，从而使亲水性显著提高。
但是，本发明所要实现的技术目的并不限定于以上所提及的问题，普通技术人员可通过以下记载明确理解未提及的其他问题。
(二)技术方案
本发明提供一种亲水性高分子纳米纤维制备方法，所述亲水性高分子纳米纤维制备方法包括：准备溶解于水的亲水性高分子溶液的步骤；准备溶解于有机溶剂的疏水性高分子溶液的步骤；将所述亲水性高分子溶液及所述疏水性高分子溶液分别注入于同轴电纺丝的内部喷嘴、外部喷嘴或内部喷嘴及外部喷嘴来进行同轴电纺丝的步骤；以及对经过所述同轴电纺丝而成的纳米纤维进行水处理来去除亲水性高分子的步骤。
在本发明中，同轴电纺丝(coaxial electrospinning)将2种高分子溶液分别向所分离的内部喷嘴和外部喷嘴注入来进行电纺丝，2种溶液通过喷嘴出来并纺丝及延伸而形成芯鞘(core-sheath)型纳米纤维。若使用双重喷嘴，可适用互不相同的高分子来制备双重结构纳米纤维，尤其，具有可纺丝没有相容性的2种高分子溶液来制备共混的纳米纤维的优点。
本发明的特征在于，将所述亲水性高分子溶液及所述疏水性高分子溶液分别向同轴电纺丝的内部喷嘴和外部喷嘴注入，通过这种方式可制备亲水性高分子位于芯且疏水性高分子位于外壳的芯/外壳形态的亲水性/疏水性混合纤维。
本发明的特征在于，所述疏水性高分子为聚氨酯。聚氨酯为相对难以进行水分散的高分子，通过本发明的方法提供这种聚氨酯纤维具有相对的亲水性的方法。相对意味着相比于没有本发明的处理的方式的聚氨酯纳米纤维，得到提高的亲水性，并且，可意味着相比于混合有亲水性高分子的混合纤维，得到提高的亲水性。
所述有机溶剂可包含选自由二甲基甲酰胺(DMF)、二甲基乙酰胺(DMAc)、甲基乙基酮(MEK)及四氢呋喃(THF)组成的组中的一种以上的有机溶剂。
所述亲水性高分子可包含选自由聚乙烯醇(polyvinyl alcohol：PVA)、聚乙烯吡咯烷酮(polyvinyl pyrrolidone，PVP)、聚氧化乙烯(polyethylene oxide，PEO)、聚丙烯酸(polyacrylic acid，PAA)、聚丙烯酸钠(poly(sodium acrylate)、羧甲基纤维素、海藻酸钠(sodium alginate(海藻酸钠))、壳聚糖、普鲁兰多糖、淀粉、明胶及胶原蛋白组成的组中的一种以上的高分子。

对包含作为最具代表性的水溶性高分子的聚乙烯醇的各种水溶性高分子水溶液和溶解于有机溶剂的聚氨酯溶液进行同轴电纺丝来制备聚乙烯醇/聚氨酯共混纳米纤维，根据此对聚乙烯醇/聚氨酯共混纳米纤维进行热水处理来去除聚乙烯醇，从而可制备亲水性得到提高的聚氨酯纳米纤维。
因此，本发明可提供包括下述步骤的亲水性得到提高的聚氨酯纳米纤维的制备方法：步骤(a)，将包含聚乙烯醇的水溶性高分子溶解于蒸馏水来制备聚乙烯醇电纺丝溶液；步骤(b)，将聚氨酯溶解于有机溶剂来制备聚氨酯电纺丝溶液；步骤(c)，将所述水溶性高分子电纺丝溶液及聚氨酯电纺丝溶液向各自的注入机构注入；步骤(d)，向与所述各自的注入机构连接的电极施加电压，通过双重同轴喷嘴排出水溶性高分子及聚氨酯溶液来进行同轴电纺丝，从而制备水溶性高分子/聚氨酯纳米纤维；步骤(e)，将水溶性高分子/聚氨酯纳米纤维内的水溶性高分子成分溶解于水来去除；以及步骤(f)，对去除水溶性高分子的聚氨酯纳米纤维进行真空干燥。

以下，通过实施例对本发明进行了更详细的说明，但这仅为具体化本发明的内容的说明，本发明的技术范围并不限定于此。
实施例1
通过电纺丝制备聚乙烯醇纳米纤维
将聚乙烯醇(Mw 88，000，99+％hydrolyzed，OCI，Korea)在蒸馏水以10％(w/v)在80℃的温度中搅拌4小时来完全溶解，从而制备聚乙烯醇电纺丝溶液之后，对其在12kV的电压、15cm的距离、0.2ml/h的排出速度的条件下进行电纺丝来制备了聚乙烯醇纳米纤维。
实施例2
通过电纺丝制备聚氨酯纳米纤维
将聚氨酯(polyester-based thermoplastic polyurethane，Lubrizol，USA)在二甲基甲酰胺以13重量百分比在常温中搅拌4小时来完全溶解，从而制备聚氨酯电纺丝溶液之后，对其在12kV的电压、15cm的距离、0.3ml/h的排出速度条件下进行电纺丝来制备了聚氨酯纳米纤维。
实施例3
制备热水处理的聚氨酯纳米纤维
将在所述实施例2中制备的聚氨酯纳米纤维放入80℃的第三次蒸馏水并缓慢地搅拌24小时之后，在常温中真空干燥24小时来制备了热水处理的聚氨酯纳米纤维。
实施例4
通过同轴电纺丝制备聚乙烯醇/聚氨酯共混纳米纤维
将聚乙烯醇(Mw 88,000，99+％hydrolyzed，OCI，Korea)在蒸馏水以10％(w/v)在80℃的温度中搅拌4小时来完全溶解，从而制备了聚乙烯醇电纺丝溶液，将聚氨酯(polyester-based thermoplastic polyurethane，Lubrizol，USA)在二甲基甲酰胺以13重量百分比在常温中搅拌4小时来完全溶解，从而制备了聚氨酯电纺丝溶液。对2种纺丝溶液在20kV的电压、15cm的距离、0.2ml/h的聚乙烯醇(core)的排出速度及0.3ml/h的聚氨酯(shell)的排出速度得到条件下进行同轴电纺丝来制备了聚乙烯醇/聚氨酯共混纳米纤维(参照图1)。
实施例5
制备热水处理的聚乙烯醇/聚氨酯纳米纤维
将在所述实施例4中制备的聚乙烯醇/聚氨酯共混纳米纤维放入80℃的第三次蒸馏水并缓慢地搅拌24小时之后，在常温中真空干燥24小时来制备了热水处理聚乙烯醇/聚氨酯纳米纤维。
形态上的观察结果
对通过所述方法制备的纳米纤维进行铂涂敷之后，使用扫描电子显微镜观察了外部形态上的结构。图2的(a)部分和(b)部分分别为聚乙烯醇及聚氨酯纳米纤维的扫描电子显微镜照片，图3为聚乙烯醇/聚氨酯共混纳米纤维的扫描电子显微镜照片，当与聚乙烯醇和聚氨酯纳米纤维的扫描电子显微镜照片进行比较时，聚乙烯醇/聚氨酯共混纳米纤维的厚度有所增加。
图4为将聚氨酯(a)及聚乙烯醇/聚氨酯共混(b)纳米纤维在80℃的蒸馏水中进行24小时的热水处理并在真空状态下干燥12小时之后所拍摄的扫描电子显微镜照片。热水处理前后虽没有显著的纤维厚度的变化，整体上呈弯曲的形态，这应该是当进行热水处理时通过残留溶剂及聚乙烯醇成分的脱离和加热的聚氨酯的热收缩引起的。
通过如上所述的结果可预估对聚氨酯及聚乙烯醇/聚氨酯共混纳米纤维进行热水处理时引起纳米纤维的微细结构上的变化，经预测，其程度同时进行残留溶解和分子量大的聚乙烯醇的脱离时产生的聚乙烯醇/聚氨酯共混纳米纤维的情况较大。
红外线分光分析结果
为了分析聚氨酯及聚乙烯醇/聚氨酯纳米纤维的成分，实施了红外线分光分析。图5为水处理之前(a)·之后((b)的聚氨酯纳米纤维和热水处理之前(c)·之后(d)的聚乙烯醇/聚氨酯共混纳米纤维的红外线分光分析结果。聚氨酯纳米纤维在3400～3200cm-1和1800～1630cm-1中产生了聚氨酯特性吸收峰值，没有产生根据热水处理有无的峰值的变化。经确认，由于聚乙烯醇的影响，聚乙烯醇/聚氨酯共混纳米纤维与聚氨酯特性吸收峰值一同产生了在3650～3000cm-1中的-OH基的强特性吸收峰值，从进行热水处理之后消失的情况去除聚乙烯醇，仅剩余聚氨酯。
13C-固体核磁共振分光分析结果
为了分析聚氨酯及聚乙烯醇/聚氨酯纳米纤维的成分，实施了13C-固体核磁共振分光分析。在图6可发现聚氨酯纳米纤维的热水处理之前(a)、之后(b)的在24～41ppm、65ppm、120～136ppm、154ppm中的聚氨酯特性峰值。聚乙烯醇/聚氨酯共混纳米纤维的热水处理之前(c)可确认45ppm、70ppm左右的聚乙烯醇特性峰值，但是在热水处理之后(d)并未产生，由此可确认，聚乙烯醇被去除并仅剩聚氨酯。
接触角检测结果
为了评价聚氨酯及聚乙烯醇/聚氨酯纳米纤维的亲水性，使用接触角检测器检测了在21℃的温度及25％±20的湿度条件下的水-纳米网表面之间的接触角。
当纯聚乙烯醇纳米纤维与水分接触时被溶解，因此并未检测。图7的(a)部分为热水处理之前的聚氨酯纳米纤维，初始接触角为133.1°，5分钟之后的接触角为130.4°。热水处理之后的聚氨酯纳米纤维的接触角为126°，5分钟之后的接触角为78.2°。图7的(b)部分为热水处理之前的聚乙烯醇/聚氨酯共混纳米纤维，初始接触角为109.8°，5分钟之后的接触角为19.8°。热水处理之后的聚乙烯醇/聚氨酯共混纳米纤维的初始接触角为82.0°，30秒之前被水完全吸收，从而没有更多的检测结果。
经预测，在聚氨酯纳米纤维中，通过热水处理的残留溶剂的脱离在纳米纤维的内侧产生微细的空间，由此引起的毛细管现象水的吸收增加。聚乙烯醇/聚氨酯共混纳米纤维基于作为水溶性高分子的聚乙烯醇的存在接触角大幅减少。如图8所示，可确认，通过作为水溶性高分子的聚乙烯醇的溶解接触角急速减少，并聚乙烯醇被溶解规定量之后接触角的减少变得缓慢。
在热水处理的聚乙烯醇/聚氨酯共混纳米纤维中，即使聚乙烯醇被去除并仅剩聚氨酯，初始接触角最小且吸收速度最快，在30秒之前完全被吸收，从而无法检测接触角，经预测，这是基于通过热水处理的聚乙烯醇及残余溶剂的脱离的微细空间产生及毛细管现象深化而水的吸收大幅增加引起的。
通过同轴电纺丝共混作为疏水性高分子的聚氨酯和如没有相容性的聚乙烯醇的水溶性高分子为可赋予亲水性的改性方法，当用作水处理基血浆过滤器或润湿性创伤覆盖材料等时，水溶性高分子成分被溶解来被处理液或血液、皮肤吸收，从而产生其导致的副作用，为防止此，附随地需要额外的交联或结晶化等水溶性高分子的不溶化工序。
根据本发明，将与聚氨酯共混的水溶性高分子通过水的溶解排他性地去除，来在纳米纤维内产生物理变化，从而相比于简单地与水溶性高分子共存，使亲水性显著提高。
所述本发明的说明仅为例示，需要理解的是，本发明所属技术领域的普通技术人员可在不变更本发明的技术思想或必要特征的情况下简单地变形为其他具体形态。因此，以上所记述的实施例在所有方面仅为例示，而不限定本发明。
