具有疏水性表面的智能调温纺织品的制备及其性能
Preperation of an intelligent thermo-regulatory textile with hydrophobic surface and its performance study
摘要
Abstract
Intelligent thermo-regulatory textiles are able to buffer and regulate the changes in ambient temperature.In this study,an intelligent thermo-regulatory textile with an obvious core-shell structure that could effectively overcome the leakage of paraffin wax was prepared using coaxial electrospinning technology with paraffin wax of a phase change temperature of 18℃as the core layer and polyvinylidene fluoride-hexafluoropropylene/nano SiO2 as the shell layer.The smart textile had a latent heat of up to 70.08J/g and showed good stability as it did not show significant change in latent heat after 400 heating-cooling cycles.This smart textile had a hydrophobic surface and the contact angle of water on the surface was increased by 16.1° compared to the textile without SiO2 nanoparticles,which can be attributed to the formation of nano-protrusions due to the exist of nano SiO2.Besides,the contact angles of acid,alkali and salt solution on the textile reached 129.4°,133.3° and 135.6°,respectively,which enabled its application in different harsh environments.The infrared imaging experiment indicated that compared with the textile without phase change materials,the time the temperature maintained above 10℃can be prolonged by 83.3%by the intelligent thermoregulated textile during the cooling process,while the time the temperature maintained below 20℃during the heating process can be prolonged by 204.76%,providing remarkable temperature regulatory capabilities.These results established a foundation for the further research on thermo-regulatory fibers with paraffin wax as phase change materials and had guiding significance for similar research on intelligent thermo-regulatory fibers.关键词
