A large amount of nano - crystals are found in the film when the sample was annealed for one hour at 500 ? with the crystallinity being increased to 50 % 研究结果发现,未经过退火处理的薄膜是纳米晶粒镶嵌于非晶介质的复合薄膜,薄膜中的结晶程度不是很高。
When anneal temperature is below 600 , the crystallinity can not be improved obviously for short anneal time , but the crystallization trend appear 退火处理后的薄膜结构分析表明,退火温度低于600时,短时间退火不能明显改善结晶状况,但结晶趋势明显。
In this paper , the crystallinity of pvc modified by homemade nucleating agent and heat treatment was increased . the maximum crystallinity reached 12 % 采用自制的成核剂对pvc进行喷液处理和热处理的各种改性,提高了pvc的结晶度,使pvc的结晶度达到了12 。
The crystallinity reach its peak when the content of epoxy is 1 % , with the increase of epoxy resin content , the crystallinity of nylon 11 alloy decreases 环氧树脂用量为1时,尼龙11共混合金体系的结晶度最大,此后随着环氧树脂的加入,尼龙11结晶度随之降低。
This structure results in very high levels of crystallinity to be achieved . these systems have been ideal models for polymer crystallization and morphological control 此外由于其高结晶度、高旋光纯度以及不含催化剂等特性,也是研究高分子结晶行为的良好模型对象。
