采用静电纺丝技术制备了聚DL-乳酸（PLA）纳米纤维，研究了这种纳米纤维的类压电响应和波导特性。由夹在电极之间的随机取向的PLA纤维组成的片材随着施加电压的增加而呈现出厚度的线性增加。这表明纤维的作用类似于压电材料。通过单向排列光纤，研究了掺杂有机染料后光纤的波导特性。来自染料的光致发光在纤维内传播，在590-670 nm处具有<44 dB cm-1的衰减。
Electrospun nanofibers are fabricated from poly(DL-lactic acid) (PLA), and the piezoelectric-like response and waveguiding properties of these nanofibers are demonstrated. A sheet composed of randomly orientated PLA fibers sandwiched between electrodes exhibits a linear increase in thickness with increasing applied voltage. This indicates that the fibers act like a piezoelectric material. The waveguiding properties of the fibers when doped with an organic dye are investigated by aligning the fibers unilaterally. Photoluminescence from the dye propagates within the fibers, with an attenuation of <;44 dB cm-1 at 590-670 nm.
