摘要
In this paper, the thermally stimulated depolarization current (TSDC) spectrum of methyl methacrylate (MMA)-grafted polypropylene is quantitatively analyzed by our TSDC peak separating algorithm. The separated trap peaks and extracted trap parameters are verified to be effective and credible by the experimental peak-separating method based on thermo-cleaning. The trap analysis on pristine and MMA-grafted polypropylene is carried out and indicates that grafting MMA can introduce a new high-depth trap peak at about 1.8 eV, meanwhile the intrinsic trap of polypropylene is deepened. This work would provide an opportunity to advance the understanding of trap characteristics in grafting-modified polypropylene.
