Hydrophobic cellulose fiber surfaces modified with 2,2,3,3,3-pentafluoropropylmethacrylate (FMA) by vapor-phase-assisted photopolymerization

Abstract

We report a simple method to produce a hydrophobic surface created by continual vapor-phase-assisted surface photopolymerization (photo-VASP) of 2,2,3,3,3-pentafluoropropylmethacrylate (FMA), which affords control over the chemical and physical properties of unique substrate surfaces without inducing any morphological changes. The photo-VASP approach was able to modify the surface of cellulose fiber substrates such as a typical, complicated, flexible and soft substrate while maintaining their original properties, imparting superior water repellency without compromising the original tactile nature of the material. The substrate surface was consecutively exposed to the vaporized initiator and monomer FMA under ultraviolet irradiation to start photopolymerization, resulting in selective coating of the irradiated surface with polymer chains. The cellulose fibers coated by the thin polymer layer retained their original tactile nature and demonstrated superior water repellency, with a controlled static contact angle 41301.

Surface modification for nano‐lignocellulose fiber through vapor‐phase‐assisted surface polymerization

“…The vapor phase‐assisted surface polymerization (VASP) method has been developed to coat many substrate surfaces with polymers, resulting in the prominent achievements of hydrophobic/hydrophilic controlling and surface grafting . It is an excellent method to preserve the delicate surfaces of materials due to the advantages of VASP process . Basically, this polymerization procedure is a solvent‐free method, taking place by gas–solid interface interaction, and provides higher grafting rate when compared to the commonly used liquid processes.…”

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

“…Vapor‐phase assisted surface polymerization (VASP) causes polymer molecules to cover over such things as nano–micro scale gaps and holes in the complex surfaces of a biomass . Moreover, VASP shows its living nature in having a proportional relation between number average molecular weight and polymer yield, and in the production of block copolymers by consecutive copolymerization.…”
