Abstract

Highlights: MNP-CDP nano-inhibitor system was prepared by grafting β-CDP to Fe3 O4 nanoparticle. MNP-CDP loading DEHP (DMCPs) were used for preparation of safe P-PVC (PVC/DMCPs). DEHP Migration, thermal and mechanical properties of PVC/DMCPs were studied. Abstract: The easy migration of di(2-ethylhexyl) phthalate (DEHP) from the plasticized PVC (P-PVC) poses a serious threat to human health and the ecosystems. Thus, its control migration from the P-PVC products is very important. In this work, a poly(β-cyclodextrin-ester) network (β-CDP) was synthesized via reaction of β-cyclodextrin with 3, 3′, 4, 4′-benzophenone tetracarboxylic dianhydride. As a potential inhibitor for reduction of the DEHP migration, the β-CDP was grafted to Fe3 O4 nanoparticles. Poly(β-cyclodextrin-ester) functionalized Fe3 O4 nanoparticles (MNP-CDP) has been used in PVC/DEHP system as a reactive nano-inhibitor to reduce DEHP migration. Thermal stability and mechanical properties of obtained films were investigated. DEHP migration tests of the P-PVC films were also carried out by using Gas chromatography. It was found that by incorporating the small amounts of nano-inhibitor in PVC/DEHP system, the migration of DEHP effectively reduced from the P-PVC samples about 65% without any serious changes in mechanical and thermal properties of the P-PVC films.
