Dual responsive polymeric nanoparticles prepared by direct functionalization of polylactic acid-based polymers via graft-from ring opening metathesis polymerization.
Polylactic acid (PLA) has found widespread use in plastics and in biomedical applications due to its biodegradability into natural benign products. However, PLA-based materials remain limited in usefulness due to difficulty of incorporating functional groups into the polymer backbone. In this paper, we report a strategy for PLA functionalization that establishes the preparation of highly deriva...
متن کاملDevelopment of novel nanocomposite adsorbent based on potassium nickel hexacyanoferrate-loaded polypropylene fabric
A nanocomposite adsorbent based on potassium nickel hexacyanoferrate-loaded polypropylene fabric was synthesized for selective removal of Cs ions from contaminated waters by a two-stage synthesis: radiation-induced graft polymerization of acrylic acid monomer onto the nonwoven polypropylene fabric surface with subsequent in situ formation of potassium nickel hexacyanoferrate (KNiHCF) nanopartic...
متن کاملPreparation of Polylactic Acid Graft Polyvinyl Acetate Compatibilizers for 50/50 Starch/PLLA Blending
Polylactic acid-g-polyvinyl acetate (PLLA-g-PVAc) was used as a compatibilizer for 50/50 starch/PLLA blend. PLLA-gPVAc with different mol% of PVAc contents were prepared by grafting PVAc onto PLLA backbone via free radical polymerization in solution process. Various conditions such as type and the amount of initiator, monomer concentration, polymerization time and temperature were studied. Resu...
متن کاملPreparation of polymer decorated graphene oxide by γ-ray induced graft polymerization.
Herein, we report a facile approach to decorate graphene oxide (GO) sheets with poly(vinyl acetate) (PVAc) by γ-ray irradiation-induced graft polymerization. The content of PVAc in the obtained sample, i.e., PVAc grafted GO (GO-g-PVAc) is calculated by the loss weight in thermogravimetric analysis (TGA) curves. A GO-g-PVAc sample with a degree of grafting (DG) of 28.5% was well dispersed in com...
متن کاملPreparation and Characterization of Nonwoven Polypropylene Fabric Irradiation-grafted with Acrylic Acid as Weakly Acidic Cation Exchange Fiber
Graft polymerization of acrylic acid onto nonwoven polypropylene (PP) fabric was carried out by a preirradiation method using a Co gamma radiation source. Results showed that 2.2'-Azobisisobutyronitrile (AIBN), its concentration was 0.2%, was very important during the grafting polymerization without removal of polymerization inhibitor of AA. The most favorable grafting polymerization conditions...
