用分子自组装技术和 Ｆ Ｔ Ｉ Ｒ Ａ Ｔ Ｒ 光谱方法研究非熔融聚丙烯复合的界面层分子相互作用，结果表明，随着自组装温度的升高， Ｐ Ｐ非晶态的９７２ 吸收峰出现了峰加宽并移向低波数的现象，说明在界面层与 Ｅ Ｖ Ａ 的乙烯链段具有相互作用，而 Ｐ Ｐ结晶态的 ９９７ 吸收峰变化不大。 Molecular self-assembly technique and F TI RATR spectroscopy were used to study the intermolecular interactions of non-melt polypropylene composites. The results show that with the increase of self-assembly temperature, P 9 amorphous 972 absorption Peak broadening and shifting to lower wavenumber indicates that there is an interaction between the ethylene layer of E V A at the interface layer and the 997 absorption peak of P P crystallizes little.
