摘要

随着人工智能高度发展，新技术对新材料的需求日渐迫切，开发新型高分子力学传感材料具有重要的科学研究意义. 本研究采用静电纺丝技术，制备聚乳酸/聚苯胺(PLA/PANI)杂化纤维膜材料，探讨了静电纺丝工艺参数，包括纺丝电压、PLA浓度对纤维形态的影响，获得最佳纺丝条件，进一步研究了添加了聚苯胺的纤维膜力学传感材料. 实验结果表明，当纺丝电压为15 kV、在溶液中PLA质量分数为7.50%、PANI质量分数为0.12%时，所得纤维形态较完整. 比较PLA及PLA/PANI纤维膜电学性能发现，PANI加入显著提升了PLA纤维膜的导电性能. 研究材料应力传感性能发现，PLA/PANI复合材料具有显著的力电传感现象，这是利用聚乳酸/聚苯胺构筑柔性应力传感器的首次报道，为后期制备聚合物力电传感器件提供了可行方案.

Abstract

With the rapid advancement of artificial intelligence

the demand for new materials driven by emerging technologies has become increasingly urgent making the development of novel high-performance polymer mechanical sensing materials of significant scientific research importance. In this study

poly(lactic acid)/polyaniline (PLA/PANI) hybrid fibre membrane materials were prepared using electrospinning method. The effects of various electrospinning process parameters

including spinning voltage and PLA concentration

on fibre morphology were investigated to determine the optimal spinning conditions. Furthermore

we examined the preparation of PLA/PANI fibre membrane mechanical sensing materials by incorporating polyaniline. The results showed that the well-defined fiber morphology was obtained at a spinning voltage of 15 kV

a PLA mass fractions solution of 7.50% and a PANI mass fraction of 0.12% of the solution. Comparing the electrical properties of PLA and PLA/PANI fibre membranes showed that adding PANI significantly increased the electrical conductivity of the PLA fibre membrane. Research the stress-sensing properties of the material has revealed that PLA/PANI composites exhibit significant piezoelectric behavior. This is the first reported instance of using PLA and PANI to construct a flexible stress sensor

providing a viable approach for the future fabrication of polymer piezoelectric sensor devices.
