Abstract

Polymers can be prepared into textiles via electrospinning. However, high overall property of outdoor clothing is necessary. In this work, hybridization and electrospinning were employed to fabricate fluoropolymer@bentonite hybrid textiles. Compared with fluoropolymer textile, hybrid textiles exhibit a surface superhydrophobicity ascribed to the significantly improved surface roughness of hybrid fibers, and they display high thermal stability attributed to inorganic bentonite. After acid/alkali immersion, ultraviolet radiation, or mechanical abrasion, hybrid textiles still show high water resistance, indicating strong weathering resistance. Rational material selection and electrospinning result in low surface energy, high surface roughness, and binary micro/nano hierarchical structure. Hybrid textile (with 10 wt% bentonite) shows high overall property (water contact angle of ~ 155°; thermal stability up to ~ 400 ℃; superhydrophobicity after 48 h exposing to acid, alkali, or radiation; hydrophobicity after 100 abrasion cycles). This work might pave a road for large-scale preparation of high-performance textiles for waterproof garments.

静电纺丝法制备防水服装用耐候超疏水聚合物/膨润土纳米复合材料

摘要静电纺丝可将聚合物制备成纺织品。然而，户外服装的高综合性能是必要的。本研究采用杂化和静电纺丝法制备fluoropolymer@bentonite杂化纺织品。与含氟聚合物纺织品相比，混杂纤维表面粗糙度的显著提高使其具有超疏水性;无机膨润土的加入使其具有较高的热稳定性。混纺纺织品经酸/碱浸泡、紫外线照射或机械磨损后，仍具有较高的耐水性，表明其耐风化性较强。合理的材料选择和静电纺丝使表面能低，表面粗糙度高，具有二元微纳分层结构。混合织物(含10 wt%膨润土)综合性能高(水接触角~ 155°);热稳定性可达~ 400℃;暴露于酸、碱或辐射48小时后具有超疏水性;100次磨损后疏水性)。这项工作为大规模制备高性能防水服装纺织品铺平了道路。
