摘　　要：超疏水材料因其卓越的防腐蚀、防覆冰和自清洁等性能,在日用纺织、生物医学和建筑涂料等领域具有巨大的发展前景。为了满足实际应用的需求,开发低成本的超疏水表面结构显得尤为重要。本文采用聚合松香(PR)作为辅助材料与聚丙烯(PP)进行熔喷纺丝,然后去除PR组分,得到多孔纤维膜,并进行十八烷基三氯硅烷改性,获得具有耐久性的超疏水材料。结果表明,PR的辅助加入可以诱导纤维变细、增加纤维膜的孔隙率,制备出的7PP/3PR纤维膜比10PP/0PR纤维膜的接触角提高了20°左右,疏水物质溶液的均匀分散增加了纤维膜的耐磨损和自清洁性能。7PP/3PR纤维膜的超疏水材料性能最佳,接触角为159.8°,历经5次摩擦循环后的接触角仍有152.6°,保留率在95.27%,而10PP/0PR纤维膜的超疏水材料的接触角保留率仅在87.46%。Superhydrophobic materials hold great promise in areas such as daily textiles,biomedicine and architectural coatings due to their excellent anti-corrosion,anti-icing and self-cleaning properties.In order to meet the demands of practical applications,it is particularly important to develop low-cost superhydrophobic surface structures.In this paper,polymerized rosin(PR)was used as an auxiliary material for melt-blown spinning with polypropylene(PP),and then the PR component was removed to obtain porous fibrous membranes,which were modified with octadecyltrichlorosilane to obtain durabe superhydrophobic materials.The results showed that the auxiliary addition of PR could induce fiber thinning and increase the porosity of the fiber membrane,and the contact angle of the prepared 7PP/3PR fiber membrane was increased by about 20°compared with that of the 10PP/0PR fiber membrane.The homogeneous dispersion of the hydrophobic substance solution increased the abrasion resistance and self-cleaning performance of the fiber membrane.The best performance of the superhydrophobic material was obtained for the 7PP/3PR fiber membrane with a contact angle of 159.8°.After 5 friction cycles,the contact angle was still 152.6°with a retention rate of 95.27%,while the superhydrophobic material of 10PP/0PR fiber membrane had a retention rate of only 87.46%.
