摘要

摘要采用静电纺丝技术制备了KNN/P(VDF-HFP)基纳米纤维复合材料。XRD和FTIR分析表明，加入KNN后，β相含量显著提高。FE-SEM显微图显示，纳米填料致密致密的形成及其在聚合物基体中的嵌入使纳米纤维均匀、光滑、均匀，无团聚现象。通过在基体中加入KNN，提高P(VDF-HFP)的诱导电荷和β相含量，改善了纳米纤维垫的压电响应，这对提高压电纳米发电机的自发电性能具有很大的潜力。

Synergistic effect of self-poled fibre based flexible lead-free KNN/P(VDF-HFP) nanofiber mat for scavenging piezoelectric energy

Abstract KNN/P(VDF-HFP) based nanofiber composite was developed by using the electrospinning technique. The significant enhanced value of β-phase content on addition of KNN is evident from the XRD and FTIR spectrum. FE-SEM micrographs reveal the formation of dense and compact nanofillers and their embedment within polymer matrix results in homogenous, smooth and uniform nanofibers without any agglomeration. The piezoelectric response of the nanofiber mat was improved by enhancing the induced charge of P(VDF-HFP) and β-phase content on incorporating KNN within the matrix, which holds great potential to improve the self-power generation performance of piezoelectric nano-generators.
