A STUDY ON CRYSTALLINE STRUCTURE OF HDPE SURFACE LAYER in Al/HDPE/Al UNDER MICROWAVE IRRADIATION

采用衰减全反射傅里叶变换红外光谱 (ATR- FTIR)和薄膜 X射线衍射 (TF- XRD)方法 ,研究了微波辐照对聚乙烯 (HDPE)在 Al/HDPE/Al界面层结晶结构的影响。结果表明 ,微波辐照可实现 HDPE界面层晶区部分的正交晶形向六方晶形转变 ,增大正交晶形晶粒尺寸和无序程度。随界面层深度增加 ,微波对

The crystalline structure of HDPE surface layer was studied by attenuated total reflection FTIR(ATR-FT-IR) and thin film X-ray diffraction(TF-XRD). The experiment results show that the orthorhombic phase changes to the hexagonal phase in HDPE surface layer during microwave irradiation, the increment tendency is weaker in the deep layer than in the shallow layer. Through microwave irradiation, the orthorhombic phase of HDPE is disordered.
