Encapsulation of Inorganic Renewable Nanofiller

Property improvement of plasticized poly(vinyl chloride) by nano‐TiO2 and poly(methyl methacrylate)–encapsulated nano‐TiO2

“…Among the developments in nanotechnology, the encapsulation of inorganic nanoparticles, such as silica , calcium carbonate , antimony trioxide , halloysite , alumina , zinc oxide , ferric oxide , and titanium dioxide (TiO 2 ) , by polymers, such as polystyrene , poly(2‐hydroxyethyl methacrylate) , poly(methyl methacrylate) (PMMA) , and poly(butyl methacrylate)‐ block ‐poly(methyl methacrylate) , has been the object of intensive research in the field of materials science and has received interest in a wide range of industrial fields. Although inorganic materials exhibit a high rigidity, thermal resistance, and mechanical strength , polymers exhibit a higher degree of flexibility, toughness, and processability.…”

“…The modified nTiO 2 particles are then well dispersed in the MMA monomer, and the process is followed by in situ differential microemulsion polymerization to produce hybrid nanoparticles of less than 50 nm in diameter. These particles are much smaller than those obtained from the conventional emulsion polymerization, and the process requires a much lower amount of surfactant than that used in the pristine microemulsion polymerization . In this study, the MMA monomer was gradually fed dropwise into the polymerizing system so as to prevent its polymerization into micelles that do not contain nTiO 2 .…”

Vinyl acetate ethylene copolymer and nanosilica reinforced epoxidized natural rubber: Effects of sulfur curing systems on cure characteristics, tensile properties, thermal stability, dynamic mechanical properties and oil resistance

“…It is well established that many desirable properties of rubber products can be achieved through rubber/rubber blend , rubber/polymer blend and rubber composites . It has been reported that latex blending offers compatible or miscible blend without phase separation and flocculation .…”

“…However, it is more beneficial to add filler and/or reinforcement into rubber. With the advance of nanotechnology, an inclusion of inorganic nanofillers at a very low loading level into rubbers has recently received much attention . Among the inorganic nanofillers, nSiO 2 has been extensively used as a nonblack nanofiller in the rubber products .…”

“…With the advance of nanotechnology, an inclusion of inorganic nanofillers at a very low loading level into rubbers has recently received much attention . Among the inorganic nanofillers, nSiO 2 has been extensively used as a nonblack nanofiller in the rubber products . Moreover, the epoxide groups of ENR and acetate groups of VAE can effectively cause a specific interaction between nSiO 2 and the matrix via hydrogen bonding, leading to a reduction in the self‐aggregation of nSiO 2 particles and also an increase in their compatibility without the aid of any coupling agents or pretreatments .…”
