聚合松香辅助制备聚丙烯熔喷纤维膜及耐久超疏水改性
Polymerized rosin assisted preparation of polypropylene melt-blown fiber film and its durable superhydrophobic modification
摘要
Abstract
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%.关键词
