摘要:

文题释义:

热塑性弹性体:一类兼具橡胶和塑料性能的材料,其交联网络结构由纳米水平的软段(弹性)和硬段(结晶型或无定型)通过热力学驱动的相分离形成,为常温下具有橡胶弹性、高温下可塑化成型的一类弹性体。

背景:聚异丁烯嵌段共聚物及其交联产物是一类新型的热塑性弹性体,具有独特性质和优异的生物相容性,有望作为医用生物材料得到广泛应用。

目的:综述聚异丁烯及其热塑性弹性体的研究进展及应用,讨论聚异丁烯类材料作为可植入医疗器材的应用前景。

方法:应用计算机检索1958至2019年PubMed数据库、Web of science数据库、中国知网和万方平台收录的与聚异丁烯生物材料相关的文献。英文检索词为“polyisobutylene and block copolymer, polyisobutylene and thermoplastic elastomer,polyisobutylene and biomaterials,polyisobutylene and modification,polyisobutylene and medical application”,中文检索词为“聚异丁烯,嵌段共聚物;聚异丁烯,热塑性弹性体;聚异丁烯,生物材料;聚异丁烯,修饰;聚异丁烯,医学应用”,按纳入、排除标准最后共纳入文献65篇进行综述。

结果与结论:聚异丁烯嵌段共聚物及其交联产物具有良好的生物相容性和稳定性。在充分利用聚异丁烯类材料自身优势的基础上,通过与不同材料的结合,利用新技术对其进行改性和修饰,未来在诸如眼科植入材料、软生物材料和药物控释载体等医用植入材料方面将展现出更强的竞争力。

Abstract:

BACKGROUND: Polyisobutylene and block copolymer and its crosslinked product are a kind of novel thermoplastic elastomer. They have unique properties and excellent biocompatibility, which is a promising medical biomaterial and applied extensively.

OBJECTIVE: To review the research progress and applications of polyisobutylene and its thermoplastic elastomers, and to discuss the application prospect of polyisobutylene-based polymers as medical implant materials.

METHODS: A computer-based retrieval of PubMed, Web of Science, CNKI and WanFang databases was conducted for the articles about polyisobutylene published from 1958 to 2019. The key words were “polyisobutylene and block copolymer, polyisobutylene and thermoplastic elastomer, polyisobutylene and biomaterials, polyisobutylene and modification, polyisobutylene and medical application” in English and Chinese, respectively. In accordance with the inclusion and exclusion criteria, 65 eligible articles were included for review.

RESULTS AND CONCLUSION: Polyisobutylene and block copolymer and its crosslinked products have favorable biocompatibility and stability. By making full use of polyisobutylene-based materials’ advantages, with the combination of other biomaterials and usage of new technology for surface modification, the copolymer will be more competitive in the field of medical implant in the future, including eye implant materials, soft biomaterials and drug delivery systems.

Key words: polyisobutylene, block copolymer, crosslinked polyisobutylene, surface modification, biomedical materials, thermoplastic elastomer, biomaterials, medical application
