摘要

聚乳酸（PLA）由于其可负担性，易用性和生物基成分而成为3D打印中的热门材料。PLA的一个显著特点是，当加热到玻璃化转变温度（Tg）以上时，它能够进行自变形，变形行为可以通过打印和结构参数进行调节，使其成为智能夹持应用的有希望的候选者。本研究定量评估了通过焦耳加热激活的电响应PLA复合材料的自变形性能。在两种场景下，使用3d打印u型样本的测试框架；材料表现出有效的自弯曲，在第一种情况下实现超过70%的变形，在第二种情况下温度升高到80°C。这些发现支持了在智能抓取应用中使用电响应PLA的潜力。

Joule Heating-Induced Self-Deformation of 3D-Printed Electrically Conductive PLA for Smart Gripping Applications

Poly(lactic acid) (PLA) is a popular material in 3D printing due to its affordability, ease of use, and bio-based composition. A notable feature of PLA is its ability to undergo self-deformation when heated above its glass transition temperature (T_g), with deformation behavior adjustable through printing and structural parameters, making it a promising candidate for smart gripping applications. This study quantitatively assesses the self-deformation performance of an electrically responsive PLA composite activated via Joule heating. Using a testing framework with 3D-printed U-shaped samples in two scenarios; the material demonstrates effective self-bending, achieving over 70% deformation in the first scenario, and a temperature increase up to 80 °C in the second. These findings support the potential of using electro-responsive PLA in smart gripping applications.
