Graft copolymerization of glass fiber and its application

Abstract

Modified glass fibers, containing unsaturated hydrocarbon surface groups, were prepared by a hydrothermal treatment, with allylglycidylether in excess as reagent. Graft polymerization of the treated glass fiber with styrene and methylmethacrylate was carried out in sealed tubes, under nitrogen, using benzoyl peroxide (BPO) and cumene hydroperoxide (CHPO) as initiators. When BPO was used as the initiator, the grafting efficiency was extremely low, but the graft copolymerization behavior was similar to that of usual organic polymers. With CHPO, both grafting ratio and grafting efficiency were very high. Various properties of composite materials containing grafted glass cloth were studied. Flexural strength, flexural modulus, and interlaminar shear strength increased proportionally to the increase of the grafting ratio; the same values were decreased only in a small extent after the boiling test.

Graft polymerization of styrene initiated by covalently bonded peroxide groups on silica

“…Indeed, the corresponding author and the Festschrift celebrant pioneered the aerosol method. On the one hand, coating of polymers on a solid inorganic surface is a subject of great interest in, e.g., biomolecule immobilization [19][20][21], colloid stabilization [22], adhesion in composite materials [23,24] and catalysis [25]. On the other hand, these particles are among the most widely used stationary phases in chromatography.…”

RAFT “grafting-through” approach to surface-anchored polymers: Electrodeposition of an electroactive methacrylate monomer

“…Another straightforward technique for the attachment of polymers to surfaces is to carry out a polymerization reaction in the presence of a substrate with tethered monomers [13][14][15][16][17][18]. In such polymerization reaction, the surface-attached monomers are incorporated into the growing polymer chains in a "grafting-through" manner, where the polymers are eventually bound to the surface after removal of excess physically adsorbed polymers.…”

Grafting of poly(acrylic acid) onto nonporous glass bead surfaces

“…Using these two methods, polymers have been grafted onto silica or porous silica surfaces. However, only a limited amount of grafting data on nonporous substrates has been reported [16][17][18][19].…”
