摘要
采用微分-积分法和裂解质谱研究了聚氯代对二甲苯膜(Parylene C膜)的非等温热降解行为。实验结果表明,Parylene C膜在N2中的热降解符合二级化学反应,其动力学模型方程式为dα/dt=Aexp(-E/RT)(1-α)2,平均表观活化能E=139kJ/mol,在N2中裂解产物主要为芳香烃和芳香醛。
The kinetic process of payrlene C degradation film was studied by combing the non-isothermal differential and integral methods. The components of decomposition were characterized by mass-spectrum. The experiment results indicated that the associated kinetic mechanism was second order chemical reaction： da/dt= Aexp（- E/RT）（1- α）^2 , The average activation energy E was 139kJ/mol , The components of decomposition were aromaticities.
