Description
技术领域
本发明属于高分子材料技术领域,具体涉及一种超疏液三维自支撑体及其制备方法。
背景技术
超疏液指对液态介质产生强烈排斥铺展行为,液态介质包括水性到油性、小分子到大分子、流体到非流体、单组份到多组份、非生物类到生物类。低表面能和多级微结构协同作用形成超疏液表面,在生活、医学、工业、海洋等领域具有广泛的应用前景,如自清洁服饰、防粘连医疗导管、油水分离、轨道交通防腐、船舶防污。在如上述的应用中,超疏液表面以二维涂层的形式依附于应用场景基底,但因基底结合力弱和耐磨性差等缺点制约着长期使用。为突破二维超疏液表面的难题,Chaohua Xue(Journal of Materials Chemistry A,2015,DOI:10.1039/c5ta01014d)和Shouwei Gao(Chemical Engineering Journal,2018,DOI:10.1016/j.cej.2017.10.006)两人发表的期刊论文涉及通过将低表面能物质聚硅氧烷的四氢呋喃溶液进行极性相(水或乙醇)分离的方法,涂覆在基底上自粗化形成具有一定结合力和耐磨性的超疏水涂层,并应用于油水分离。
Chaohua Xue和Shouwei Gao两人发表的期刊论文涉及通过相分离制备超疏液表面,该技术方案大量使用四氢呋喃非环保有机溶剂,且仍需依附于基底,基底结合力和耐磨性不理想的缺点并未从根本上解决,且只适用于超疏水表面的制备。
发明内容
鉴于此,有必要针对上述问题提供一种超疏液三维自支撑体及其制备方法。
本发明是通过以下技术方案实现的:
一种超疏液三维自支撑体的制备方法,包括:
分别配制连续相和分散相;将所述连续相和所述分散相混合形成乳液;将所述乳液注入容器;排气泡,固化,脱水,脱离容器后即得超疏液三维自支撑体。
进一步的,所述“分别配制连续相和分散相”中连续相的配制包括:
(1)将聚二甲基硅氧烷和其衍生物按质量比5:2~9混匀形成连续相;
(2)将步骤(1)所得的连续相与固化剂按100:5~15(优选9:1)的质量比混匀。
进一步的,所述的聚二甲基硅氧烷的封端为三甲基硅氧烷、乙烯基、甲氧基、氨丙基或羟基中的一种。
进一步的,所述的聚二甲基硅氧烷的衍生物为聚二甲基硅氧烷-异佛尔酮二异氰酸酯、聚二甲基硅氧烷-4,4'-二苯基甲烷二异氰酸酯、聚二甲基硅氧烷-聚芳醚或聚二甲基硅氧烷-聚乙酸乙烯酯中的一种。
进一步的,所述的固化剂为二丁基二月硅酸锡、含氢硅油、正硅酸乙酯、多烷氧基硅烷或多氨基硅烷中的一种。
进一步的,所述“分别配制连续相和分散相”中分散相的配制包括:将极性介质与纳米颗粒按质量比10:1~7混匀形成分散相。
进一步的,所述的极性介质为水、质量浓度为7~15%的阳离子型含氟聚丙烯酸酯水溶液、质量浓度为6~35%的阴离子型含氟聚丙烯酸酯水溶液或质量浓度为5~15%的非离子型含氟聚丙烯酸酯水溶液中的一种。
进一步的,所述的纳米颗粒为二氧化硅纳米颗粒、二氧化钛纳米颗粒或三氧化二铝纳米颗粒中的一种。
进一步的,所述的“将所述连续相和所述分散相混合形成乳液”具体操作包括:将所述分散相在搅拌下逐滴加入所述连续相中形成乳液。
进一步的,所述连续相和所述分散相的质量比20:3~15。
进一步的,所述的逐滴加入速度为10~120秒/滴。
进一步的,所述的乳化搅拌速度为500~3000rpm。
进一步的,所述乳液可根据自支撑体应用所需的形状注入对应形状的模具容器中。
进一步的,所述“排泡”操作包括:保持容器开放,室温下抽真空排泡。
进一步的,所述抽真空的操作时间为20~120min。
进一步的,所述“固化”操作包括:保持容器封闭,热固化乳液。
进一步的,所述的热固化的操作条件为:温度为50~80℃,热固化时间为30~150min。
进一步的,所述“脱水”操作包括:保持容器开放,热脱除分散相中的水。
进一步的,所述的热脱除水的操作条件为:温度为100~180℃,热脱除时间为1.5~5h。
一种由上述方法制得的超疏液三维自支撑体,具有多孔微结构,所述微孔结构的单个微孔直径小于20微米,可储存大量空气,降低与液体的接触面积,从而实现对水和油类液体优异的排斥铺展效果。
本发明有益效果:
本发明开发一种绿色方法制备超疏液三维自支撑体,克服了现有二维超疏液表面须依附于基底、不宜独立使用,且存在基底结合力弱和耐磨性差的缺点,无需基底,即无基底结合力问题,且可独立使用。本发明制得的超疏液三维自支撑体具有三维的柔性聚合物结构,使其具备了强耐磨性。
本发明的技术方案以聚二甲基硅氧烷/聚二甲基硅氧烷衍生物为连续相和环保型介质为分散相,通过乳化方式热固化/脱水后形成超疏液三维自支撑体。此方法易操作,非常适于工业应用,所制备的超疏液三维自支撑体无需基底,可独立使用,耐磨性强,对水和油类液体有优异的排斥铺展效果。
