摘要 4D打印是将科学与工程技术相结合的一门新兴技术。自2013年首次被提出后.由于其可以响应外部刺激,具备随时间的推移有结构或功能变化的独特能力.引起了广泛关注。而智能响应材料是4D打印中最重要的因素。该文综述了近年来国内外4D打印用水凝胶和相关新技术在植入性医疗器械领域的研究进展。然后指出了目前4D打印用响应材料的局限问题。最后,展望了4D打印技术在植入性医疗器械领域的发展方向。 Four-dimensional(4D)printing is an emerging technology that combines science and engineering techniques.The term,“4D printing”was coined in 2013 and since then it has attracted a lot of interests due to its unique ability to have structural or functional transformations over time in response to external stimuli.The most important element of 4D printing is the responsive material.The recent progress research of hydrogels and related new technologies for 4D printing was summarized in the field of implanted medical devices at home and abroad in this paper.Then,it was pointed out the problems of responsive materials for 4D printing.Finally,it was prospected that the development of 4D printing technology in the field of implantable medical devices.
