Nanocomposites with polymer matrix offer excellent opportunities to explore new functionalities beyond those of conventional materials. TiO, as a reinforcement agent in polymeric nanocomposites, is a viable strategy that significantly enhanced their mechanical properties. The size of the filler plays an essential role in determining the mechanical properties of the nanocomposite. A defining feature of polymer nanocomposites is that the small size of the fillers leads to an increase in the interfacial area compared to traditional composites. The interfacial area generates a significant volume fraction of interfacial polymer, with properties different from the bulk polymer even at low loadings of the nanofiller. This review aims to provide specific guidelines on the correlations between the structures of TiO nanocomposites with polymeric matrix and their mechanical properties. The correlations will be established and explained based on interfaces realized between the polymer matrix and inorganic filler. The paper focuses on the influence of the composition parameters (type of polymeric matrix, TiO filler with surface modified/unmodified, additives) and technological parameters (processing methods, temperature, time, pressure) on the mechanical strength of TiO nanocomposites with the polymeric matrix.
具有聚合物基体的纳米复合材料为探索超越传统材料的新功能提供了绝佳机会。二氧化钛作为聚合物纳米复合材料中的增强剂,是一种显著提高其机械性能的可行策略。填料的尺寸在决定纳米复合材料的机械性能方面起着至关重要的作用。聚合物纳米复合材料的一个显著特征是,与传统复合材料相比,填料尺寸小导致界面面积增加。界面面积产生了显著体积分数的界面聚合物,即使在纳米填料低负载量时,其性能也不同于本体聚合物。本综述旨在提供关于二氧化钛纳米复合材料与聚合物基体的结构及其机械性能之间相关性的具体指导方针。这些相关性将基于聚合物基体与无机填料之间实现的界面来建立和解释。本文重点关注组成参数(聚合物基体类型、表面改性/未改性的二氧化钛填料、添加剂)和工艺参数(加工方法、温度、时间、压力)对二氧化钛与聚合物基体纳米复合材料机械强度的影响。
