摘要:

文题释义:
无机纳米填料:无机填料通常是一种颗粒状的材料形式,尺寸在纳米范围内的粒子或微粉称为无机纳米材料,它的微小尺寸特征提供了与常规填料不同的性质:①与聚合物基体的界面面积非常大;②与尺寸有关的物理特性。在生物材料应用领域,将无机纳米填料嵌入聚合物基体中可构成复合材料以改善生物相容性或构建具有特定功能的材料。
植入硅橡胶:一种用于外科治疗用途的硅橡胶,是制备用于人体组织、器官缺损或失功的修复重建的人工器官和假体,以及各种引流作用的管材、片材、型材的基本医用生物材料,主要化学成分为高分子质量聚二甲基和甲基乙烯基硅氧烷的共聚物。

背景:硅橡胶是人体组织、器官外科修复重建的常用生物材料,但其自身存在生物相容性缺陷,无机纳米填料为植入硅橡胶的生物相容性改良和构建具有特定功能的复合材料提供了新契机。
目的:综述植入硅橡胶添加无机纳米填料改性在生物相容改良研究方面已取得的成果及不足。
方法:在PubMed、Web of Science和Medline等英文生物医学数据库,输入“siloxane,silicone rubber,inorganic nano-filler,metal nano-filler,metal oxide nano-filler,carbon nanoparticles”关键词,在万方、CNKI和维普等中文数据库输入“硅橡胶、无机纳米填料、纳米金属、纳米金属氧化物、纳米碳”关键词,分别检索出与无机纳米填料改性硅橡胶的相关文献,时间跨度从2014年1月至2020年10月。
结果与结论:利用纳米金属及其氧化物和纳米新碳填料对植入硅橡胶本体或表面进行改性,增进了硅橡胶的生物相容性,可在细胞生长、抗凝血、表面特性、力学性能、耐久性、抗感染功能化等方面产生积极影响。未来需研究不同纳米填料对硅橡胶表面性质(如拓扑结构、电荷、湿润性)造成的细胞增殖移行机制、纳米金属杀菌剂在硅橡胶表面控释阳离子的细菌-纳米粒子相互作用调节策略,以及植入后潜在的纳米毒性。

Abstract: BACKGROUND: Silicone rubber is a common biological material for surgical repair and reconstruction of human tissues and organs. Due to the shortcomings of silicone rubber’s own biocompatibility, inorganic nano-fillers provide new opportunities for the biocompatibility improvement of implanted silicone rubber and the construction of composite materials with specific functions.
OBJECTIVE: To review the achievements and deficiencies in the research on biocompatibility of implanted silicone rubber by adding inorganic nano-fillers.
METHODS: To enter the keywords “siloxane, silicone rubber, inorganic nano-filler, metal nano-filler, metal oxide nano-filler, carbon nanoparticles” on English biomedical databases PubMed, Web of Science and Medline, and those in Chinese with same meaning as English on Chinese databases Wanfang, CNKI and VIP, to harvest the related articles on inorganic nano-filler modified silicone rubber. The time span was from January 2014 to October 2020 .
RESULTS AND CONCLUSION: Metal and their oxide nanoparticles as well as new carbon nano-fillers can improve the biocompatibility of the implanted silicone rubber by body or surface modification, which have a positive impact in the aspects of cell growth, anticoagulation, surface properties, mechanical properties, durability, anti-infective functionalization and so on. In the future, it is necessary to study the mechanism of cell proliferation and migration caused by different nano-fillers on the surface properties of silicone rubber, such as topological structure, charge, and wettability, the regulation strategies and planting of nano-metal bactericides to control the release of cations on the surface of silicone rubber, also the potential nano-toxicity after being implanted.

Key words: silicone rubber, inorganic nano-filler, nano metal, nano metal oxide, nano carbon, carbon ion, carbon nanotube, graphene
