Commodity polymers are produced in large volumes, providing robust mechanical properties at relatively low costs. The products made from these commodity polymers typically offer only static functionalities. Over the past decade, however, in the scientific literature, stimuli-responsive additives and/or polymer coatings have been introduced to commodity polymers, yielding composites and bilayers that change shape in response to light, temperature, and/or humidity. These stimuli responsive commodity polymers allow the marketing and sales of these otherwise bulk products as "high-end" smart materials for applications spanning from soft actuators to adaptive textiles. This Spotlight on Applications presents an overview of recent intriguing works on how shape changing commodity polymer composite and bilayer actuators based on polyamide 6, poly(ethylene terephthalate), polyethylene, and polypropylene have been fabricated that respond to environmental stimuli and discusses their potential applications.
通用聚合物产量巨大，能以相对较低的成本提供强大的机械性能。由这些通用聚合物制成的产品通常仅具备静态功能。然而，在过去十年中，科学文献里已将刺激响应性添加剂和/或聚合物涂层引入通用聚合物中，从而产生了能响应光、温度和/或湿度而改变形状的复合材料和双层材料。这些刺激响应性通用聚合物使得这些原本普通的产品能够作为“高端”智能材料进行营销和销售，应用范围涵盖从软致动器到自适应纺织品等领域。本应用聚焦概述了近期一些有趣的研究工作，这些工作涉及如何制造基于聚酰胺6、聚对苯二甲酸乙二酯、聚乙烯和聚丙烯的形状可变通用聚合物复合材料及双层致动器，它们能够响应环境刺激，并探讨了其潜在应用。
