摘要
硅橡胶凭借其诸多优异性能在国防与民用领域获得了越来越广泛的应用,成为其他材料所不能相比和替代的高分子材料,但力学性能差严重制约其发展,因此硅橡胶改性一直是科技工作者关注的焦点。重点从化学改性、添加功能填料两个方面阐述了国外在硅橡胶改性方面的研究进展,并综述了近几年国外在硅橡胶材料性能评估方面开展的研究工作,提出硅橡胶材料未来的发展方向。
Silicone rubbers are of broad appeal due to their chemical and mechanical properties.However,a major drawback of pristine silicone rubber is that it exhibits very low mechanical properties as a result of their very weak intermolecular forces between polymer chains.In order to reach reasonable mechanical properties,silicone rubber must be modified and filled with reinforcing fillers.Moreover,recent progress in the performance evaluation for silicone rubber materials and ultimately come up with future directions are concerned.
