Functional surfaces by plasma grafting of itaconic acid onto polypropylene mesh: synthesis and structural investigations

Abstract

AbstractPolypropylene (PP) is an unflinching element of biomaterials for human healthcare, leading to enormous possibilities for their functional development within a broad range of biocompatible and bioreceptive materials. Plasma grafting of itaconic acid was carried out on a PP surface by oxygen plasma activation. The variation of grafting parameters, such as monomer concentration, reaction temperature and reaction time, as a function of the degree of grafting was investigated. The graft distribution and surface homogeneity of the PP surfaces were evaluated using confocal microscopy, field emission scanning electron microscopy and atomic force microscopy. These surface characterizations led to information about the impact of grafts on the material surface. © 2023 Society of Industrial Chemistry.
