Abstract

Poly(lactic acid) (PLA) as shape memory material has gained attention due to its biocompatibility, biodegradability, and ease of processing by 3D printing. PLA’s environmentally friendly nature makes it an attractive candidate for sustainable and recyclable shape memory applications. However, PLA’s slow shape recovery rate and low shape fixation percentage hinder its applicability as shape memory material. In the present study, we report MXene-modified PLA (PLA/Mx) nanocomposite with enhanced shape memory effect. Solution processing methods mediated the loading of the MXene in the PLA matrix. Different samples were prepared by varying the weight% of the MXene in the PLA matrix. The structure and morphology of samples were analyzed by XRD and TEM characterization. Thermogravimetric analysis was performed to measure the thermal stability of the composite. Compared with pure PLA, with MXene loading, the PLA/Mx composites show an increase in thermal. The shape recovery study on PLA/Mx samples used temperature as an external stimulus. The PLA/Mx composite exhibited a significantly improved shape memory effect than the PLA alone. The study exhibits that a shape memory effect can be improved by tuning the MXene additive loading in the PLA matrix. The material shape recovery effect was validated by fabricating the spiral structure. The fast shape recovery time 3s and shape fixation/recovery of > 95% was observed for 1 wt% of PLA/Mx. The PLA/Mx composite is expected to contribute significantly to implementing innovative shape memory applications, particularly in the biomedical field for sutures, controlled drug release, and minimally invasive devices.

具有均衡力学性能的聚乳酸-二甲苯纳米复合材料工程,可增强形状记忆效果
聚乳酸(PLA)作为形状记忆材料,因其生物相容性、生物可降解性和易于三维打印加工而备受关注。聚乳酸的环保特性使其成为可持续和可回收形状记忆应用的理想候选材料。然而,聚乳酸的形状恢复速度慢、形状固定率低,阻碍了其作为形状记忆材料的应用。在本研究中,我们报告了具有增强形状记忆效果的 MXene 改性聚乳酸(PLA/Mx)纳米复合材料。溶液加工方法有助于在聚乳酸基体中添加 MXene。通过改变聚乳酸基体中 MXene 的重量百分比制备了不同的样品。通过 XRD 和 TEM 表征分析了样品的结构和形态。热重分析用于测量复合材料的热稳定性。与纯聚乳酸相比,随着 MXene 的加入,聚乳酸/Mx 复合材料的热稳定性有所提高。聚乳酸/Mx 样品的形状恢复研究使用温度作为外部刺激。聚乳酸/Mx 复合材料的形状记忆效果明显优于单独的聚乳酸。该研究表明,通过调整聚乳酸基体中的 MXene 添加剂含量,可以改善形状记忆效果。通过制造螺旋结构验证了材料的形状恢复效果。当聚乳酸/Mx 的含量为 1 wt% 时,形状恢复时间为 3 秒,形状固定/恢复率为 95%。聚乳酸/Mx 复合材料有望为实现创新的形状记忆应用做出重大贡献,尤其是在生物医学领域的缝合、药物控释和微创设备方面。

期刊介绍: Journal of Polymer Research provides a forum for the prompt publication of articles concerning the fundamental and applied research of polymers. Its great feature lies in the diversity of content which it encompasses, drawing together results from all aspects of polymer science and technology. As polymer research is rapidly growing around the globe, the aim of this journal is to establish itself as a significant information tool not only for the international polymer researchers in academia but also for those working in industry. The scope of the journal covers a wide range of the highly interdisciplinary field of polymer science and technology, including: polymer synthesis; polymer reactions; polymerization kinetics; polymer physics; morphology; structure-property relationships; polymer analysis and characterization; physical and mechanical properties; electrical and optical properties; polymer processing and rheology; application of polymers; supramolecular science of polymers; polymer composites.
