使用近年来发展的构象弹性理论研究聚乙烯在不同应变下内能对弹性力的贡献fe/f,计算得到的fe/f值与实验值大体一致,结果表明fe/f主要由分子内相互作用力贡献,并且fe/f依赖于应变.
The Cone elastic theory developed in recent years has been used to study the contribution of internal energy to elastic force of polyethylene at various strains, fe / f. The calculated fe / f values are in good agreement with the experimental values. The results show that fe / f is mainly composed of intramolecular interactions Contributions, and fe / f are dependent on strain.
