Flexible acrylic-polyurethane based graft-interpenetrating polymer networks for high impact structural applications

Recycled polyethylene/polycarbonate blends compatibilized with oxidized polyethylene/CaCO3

“…The improved phase homogeneity, increased melt‐viscosity, and other associated key properties of the recycled blends are attributed to the presence of CaCO 3 in rLDPE, which in conjunction with OPE compatibilizer, facilitates the formation of the interpenetrating network in the blends 59,60 . It is reported elsewhere that calcite mineral has a rhombohedral crystal structure that can be cleaved and can produce a polar surface with alternating Ca 2+ and CO 3 2− ions.…”

Effect of nanofillers on polyurethane/polystyrene matrix nanocomposites: Characteristics and forthcoming developments

“…The 20 wt% polyurethane content in graft copolymer improved the fracture toughness to 2.2 ± 0.19 MPa.m 1/2 , relative to that of the simply blended polymers (1.61 ± 0.16 MPa m 1/2 ). Alizadeh et al 106 explored high impact structural applications for the polyurethane/polystyrene interpenetrating polymer. Energy to maximum load for the stimuli-responsive membrane was found as 131.10 ± 7.35 J.…”

Interpenetrating polymer network hydrogels using natural based dyes initiating systems: Antibacterial activity and 3D/4D performance

“…As previous studies of our group have demonstrated that some dyes derived from natural plants can be used as photoinitiator, which can not only initiate free radical polymerizations (of PEG-DA for instance) but also induce the cationic polymerization of epoxides such as EPOX under visible light irradiation [24][25][26][27]. EPOX is a commonly used flexible monomer that can be introduced into PEG-DA as a second network to prepare IPN hydrogels [28][29][30].…”
