物理交联 meaning in English
physical crosslinking
Examples
- When the content of vermiculite minerals was about 10 % , the impact strength ( nick ) and the flexural strength had maximum value , but those of the polybenzoxazine ( bisphenol a type ) / phlogopite composites had been going down . as the content of vermiculite minerals was over 5 % . hdt of the polybenzoxazine ( bisphenol a type ) / vermiculite hybrid nanocomposites was higher than that of the polybenzoxazine ( bisphenol a type )
4几插层状分散的10蛙石含量的纳米复合材料的物理交联作用表现较为明显，力学性能处于峰值； hdt高于纯树脂，并随含量的增加而提高，含金云母的复合材料的hdt则不随其含量变化而变化。 - It also has stronger hydrogen bond which can result in partly physical crosslinkage in polymers , which can fasten orienting of chromophore . all these benefit to obtain high nlo coefficient . in chapter one , some basic conceptions about lc and the advance in lcpu are described , especially the synthesis methods on lcpu and the influence factors of lcpu formation liquid crystalline phase
聚氨酯液晶是分子排列具有一定取向的聚合物材料，可为非线性光学聚氨酯提供一种较好的非对称取向的介质环境，聚氨酯中还存在较强的氢键作用，使得聚合物材料有部分物理交联，能固定发色团的取向，这些因素有利于获得较大的非线性光学效应。 - Nano - al2o3 particles which are embedded in the matrix can impart additional strength to the composite and act as bearing of stress . furthermore , these organically - treated particles can effectively link the molecular chains of pa6 , and this state is similar to physical crosslinking joints . all these together contribute to the improvement of mechanical properties and hardness
硬度试验表明，随纳米al _ 2o _ 3填充粒子量的增加，材料的硬度呈现增加趋势，这主要是因为纳米al _ 2o _ 3在尼龙6中类似于“物理交联” 、充当刚性支撑点作用，从而使尼龙6的硬度提高。
