摘要
Abstract
In this study, a polyurethane(PU) and polyvinyl butyral(PVB) three-dimensional(3D) nanofiber porous sponge structure was prepared. Its morphology and structure were characterized by SEM, XRD and FTIR, and the mechanical properties were investigated by tensile and compressing tests. SEM results revealed that for the three-dimensional structure of different PU︰PVB ratios, there existed differences in fibre morphology and the interfibrous crosslinking. As proved by XRD and FTIR results, PU and PVB polymeric molecules existed in the 3D nanofiber sponge, and it was clarified that there exited crosslinking between PU molecules and PVB molecules. Experiments showed that when the mass ratio of PU and PVB was 7︰3, the fiber morphology of the 3D nanofiber sponge was good, the structure was stable, a breaking strength of 2. 2 MPa, and a breaking elongation of 175. 5％. The porous fiber lightweight sponge has excellent compression and resilience performance, and it can be applied in different fields.关键词
