Again 190 DEG C are warming up to from 160 DEG C with the heating rate of 2 DEG C/min, and 2h is incubated in the case where temperature is for 190 DEG C;
Again 230 DEG C are warming up to from 190 DEG C with the heating rate of 2 DEG C/min, and 1h is incubated in the case where temperature is for 230 DEG C;
Finally room temperature is cooled to as 230 DEG C from temperature with the rate of temperature fall of 2 DEG C/min, obtains the substrate containing polyimides;
5th, demoulding:Substrate containing polyimides is placed in distilled water, makes polyimides come off from substrate, reuse steaming Distilled water rinses well polyimides, then is dried 2h in the case where temperature is for 120 DEG C, obtains optically transparent light-coloured high temperature resistant shape note Recall polymer.
