具有优良的力学和疏水性能的复合薄膜在惯性约束物理实验中具有重要作用.在本文中,我们使用简单的溶液混合的方法合成了低聚倍半硅氧烷/聚酰亚胺(POSS/PI)复合薄膜.结果表明由于POSS的引入,力学性能和疏水性能显著增强.力学测试结果显示,当POSS质量分数为10%时,弹性模量和硬度分别达到29.29 GPa和29.29 MPa,相比纯的PI薄膜为14.9 GPa和0.64 MPa.同时,当POSS质量分数为20%,复合薄膜的接触角为83.59°,明显高于纯的PI薄膜(66°).因此,POSS/PI复合膜比纯PI薄膜显示了强大的生命力和极其广阔的应用前景在惯性约束聚变(ICF)物理实验中.
Composite membranes with excellent mechanical and hydrophobic properties play an important role in inertial confinement physics experiments.In this paper, we synthesized oligosilsesquioxanes / polyimides (POSS / PI) using a simple solution mixing method ) Composite film.The results show that the mechanical properties and hydrophobicity of POSS are significantly enhanced.Mechanical test results show that when POSS mass fraction is 10%, the elastic modulus and hardness reach 29.29 GPa and 29.29 MPa respectively, PI films were 14.9 GPa and 0.64 MPa, respectively.The POSS mass fraction was 20%, the contact angle of the composite films was 83.59 °, which was significantly higher than pure PI films (66 °) Films show great vitality and extremely broad application prospects in inertial confinement fusion (ICF) physics experiments.
