在本文中,用在火棉胶薄膜上、流体介质表面上和在玻片上蒸发聚乙烯的二甲苯溶液的方法,研究了在不同温度(由30到135℃)和不同浓度(0.1,0.01,0.001%)下得到的聚乙烯的各种结晶形态。依赖于不同温度和浓度,可以得到有规则外形的晶体、树枝晶、球晶、纤维晶和由规则晶体向球晶的过渡形态以及大小不均一的球粒等。 根据实验所得的结果,作者对这些不同的结晶形态及其与结晶条件的相互关系进行了讨论。
In this paper, the effects of different temperatures (from 30 to 135 ° C) and different concentrations (0.1, 0.01, 0.001%) obtained under the various crystalline forms of polyethylene. Depending on the temperature and the concentration, crystals with regular shapes, dendrites, spherulites, fibrous crystals and transitional forms from regular crystals to spherulites and spherulites of non-uniform size can be obtained. Based on the experimental results, the authors discuss these different crystalline forms and their relationship to the crystallization conditions.
