Flexural strength of experimentally filled resins made of electron beam irradiated silica fillers

Influence of ionizing radiation on the mechanical properties of BisGMA/TEGDMA based experimental resin

“…With regards to the silica used as filler in the preparation of the experimental composites, Behr et al (2009) reported that the flexural strength of experimental composites filled with silanized silica could be improved by irradiation. The coupling agent poly (methylphenylsilane), when submitted to radiation, undergoes intermolecular crosslinking and forms a three-dimensional network (Herden et al, 1998).…”

Improvement of thermal stability of polypropylene using DOPO-immobilized silica nanoparticles

“…As the polymer coating formed, the surface of silica nanoparticle is altered from hydrophilic to hydrophobic and therefore, the aggregations of silica nanoparticles are dramatically decreased. Surface modification with silane coupling agents has also been actively investigated to decrease the aggregation of the nanoparticles as well as improve interaction between filler and matrix [5, 9–18]. It was found that surface modification with vinylsilanes could decrease the secondary agglomerate structures.…”

“…Methacryloxypropyltrimethoxysilane was used to improve the interaction of the silica nanoparticles and matrix. The mechanical strength of filled resins could be enhanced by advance preparation of silica fillers with silane coupling agents followed by electron beam irradiation [18]. …”
