Effects of poly-（p-phenylene terephthamide） powder coated with polydopamine on ethylene-propylene-diene-terpolymer grafted maleic anhydride

In this paper, we report a technique for the surface modification of poly-（p-phenylene terephthamide） （PPTA） powder coated with polydopamine （PDOPA）. We used air oxidation to self-polymerize dopamine （DOPA） to ensure that the PPTA powder was coated. Our results indicate that the modified surface of...

Summary:In this paper, we report a technique for the surface modification of poly-（p-phenylene terephthamide） （PPTA） powder coated with polydopamine （PDOPA）. We used air oxidation to self-polymerize dopamine （DOPA） to ensure that the PPTA powder was coated. Our results indicate that the modified surface of PPTA powder enhances compatibility with the polymer matrix without damaging its structure. Additionally, it is possible to control the coating thickness of PDOPA by regulating the reac- tion time. The modified PPTA powder improved the comprehensive property of ethylene-propylene-diene-terpolymer grafted maleic anhydride （EPDM-g-MAH）, and it proved that this method can enhance the strength and electric insulativity of EPDM-g-MAH.
