| titleOfInvention | Preparation method of perylene-3,4,9,10-tetracarboxylic dianhydride graft modified polypropylene film |
| abstract | Disclosed is a preparation method of perylene-3,4,9,10-tetracarboxylic dianhydride grafted modified polypropylene film, in the method, the first predetermined mass fraction of perylene-3,4,9,10-tetra Carboxylic acid dianhydride, be dissolved in the non-polar organic solvent under continuous first stirring condition and obtain long-term stable PPDI solution at room temperature; Weigh the 2-methallylamine of the second predetermined mass fraction, in continuous Under the second stirring condition of being dissolved in PPDI solution to react to obtain PPDI alkenylation solution; Weigh the PPDI powder, initiator and polypropylene of the alkenylation of the third predetermined mass fraction, be dissolved in non-polar organic solvent; Add a predetermined amount of acetone solution to the perylene-3,4,9,10-tetracarboxylic dianhydride grafted polypropylene solution under ice-water bath conditions to separate out solid product crystallization; Form a thin film sample to obtain an N-type molecular semiconductor graft-modified polypropylene film. |
