同轴聚氨酯传感复合纤维的制备及其性能研究
Preparation and Properties of Coaxial Polyurethane Sensing Composite Fiber
摘要
Abstract
In order to balance the mechanical and sensing properties of elastic sensing polyurethane fibers,TPU was taken as the core layer of coaxial fiber,TPU、GO、C2 AgF3 O2 composites as out layer,the fiber outer sensing layer was in-situ reduced with L-AA to form a sensing layer integrating TPU,rGO and AgNPs,and TPU-AgNPs-rGO-TPU sensing fibers were prepared.Tensile and sensing properties of the sensing fibers with differ-ent parameters were studied.The results showed that the optimal balance between mechanical and sensing proper-ties of the fiber was achieved with 30%TPU as core layer and AgNPs,1.5%rGO and 15%TPU composite as out layer.The tensile strength was 23.01 MPa and elongation at break was 576.23%.TPU-AgNPs-rGO-TPU fiber could effectively sense the external stimulation,possessing high sensitivity characteristics(highest GF was 44.61),and the electrical conductivity was 173.55 ms/cm.The fiber could sustainably detect human motions and physiological signals,demonstrating promising application prospect.关键词
