Adhesion control of interface between cellulose and polypropylene by vapor-phase assisted surface copolymerization

Adhesion control of interface between cellulose and polypropylene by vapor-phase assisted surface copolymerization
Satoshi Gomi, Haruo Nishida
In order to achieve the effective interface bonding between biomass microfiller and commodity plastics, consecutive copolymerization of hydrophilic acrylic acid (AA) and hydrophobic butyl acrylate (BA) using vapor-phase assisted surface polymerization (VASP) technology was applied to prepare microcomposites consisting of cellulose microcrystal (CμC) and polypropylene (PP). After the copolymerization by VASP, CμC surfaces were covered by accumulated polymers: P(AA-co-BA) including block-type copolymer and homopolymers of 6.2–25.3 wt % versus CμC. Although structures of the products were unspecified, it was expected to be mixtures of block copolymers and homopolymers. Subsequently prepared P(AA-co-BA) on CμC/PP (5/95 wt/wt) composites expressed a superior mechanical toughness, which had increased threefold when compared to intact CμC/PP composite. This increase in toughness was mainly based on an increase in elongation rate, reflecting improvement of the adhesion strength at the interface between CμC surface and PP. The trace amounts: 0.31 wt % of accumulated P(AA-co-BA) on CμC surface must function as an effective adhesive/compatibilizer at the interface. © 2017 Wiley Periodicals, Inc. J. Appl. Polym.
