Green Preparation and Sensing Properties of Stretchable Elastic Fibers Mechanically Enhanced by Feather Microfibers
摘要
Abstract
With the rapid development of artificial intelligence technology,conductive elastic fiber has attracted more attention of researchers.However,there is a lack of green,efficient preparation and mechanical performance improvement strategies of tensile conductive fiber,which seriously restricts its wider application.Polymerizable deep eutectic solvent(PDES)is a good way for preparing ionic conductive gel materials due to its good dissolution ability to a variety of polymers.A new polymerizable deep eutectic solvent system based on calcium chloride-choline chloride-acrylic acid(CaCl2-PDES)was designed for the green preparation of conductive fibers for enhanced mechanical properties of protein microfibers.The results show that when the concentration of CaCl2 is 2 wt.%and the dissolution temperature is 120℃,feathers can be decomposed into micron scale(about 5 μm in diameter),and the presence of protein staple fibers enhanced the mechanical properties of PAA-ChCl based conductive fibers(1.7 times higher fracture strength,0.62 MPa).While protein microfiber gives fiber good mechanical properties,it also maintains good sensing properties and fatigue resistance and elasticity.The prepared feather ion gel fiber has fast and timely electrical signal response(133 ms and 172 ms respectively)and good sensitivity(GF 0.78～1.44).This work has effectively alleviated the problem of high-value reuse of waste biomass feathers,and provided a new horizon for the green preparation of biomass elastic conductive fiber.关键词
