Preparation and properties of nanocomposites based on acrylonitrile–butadiene rubber, styrene–butadiene rubber, and polybutadiene rubberAbstract Nanocomposites were prepared with different grades of nitrile rubber with acrylonitrile contents of 19, 34, and 50%, with styrene–butadiene rubber (23% styrene content), and with polybutadiene rubber with Na‐montmorillonite clay. The clay was modified with stearyl amine and was characterized by X‐ray diffraction (XRD), Fourier transform infrared (FTIR) spec... ... hiện toàn bộ

Modelling of water transport in ionic hydrophilic polymersAbstract Water and ion transport in thin sheets of initially dry, ionic, hydrophilic crosslinked polymers was modelled throughout the dynamic swelling process. The water transport was expressed in terms of a non‐Fickian equation with a diffusion term containing a Fujitatype concentration‐dependent diffusion coefficient coupled with a pseudoconvective term arising fr... ... hiện toàn bộ

FTIR analysis of hydrogen bonding in amorphous linear aromatic polyurethanes. II. Influence of styrene solventAbstract Fourier‐transform infrared (FTIR) spectral studies were carried out on a polyurethane in styrene solutions at styrene concentrations from 30 to 90% (w/w). NH vibrations were studied in the stretching and bending regions. The results demonstrated that the NH groups of the polyurethane can hydrogen bond not only with the CO groups but also with other group... ... hiện toàn bộ

Hole‐growth instability in the dewetting of evaporating polymer solution filmsAbstract We investigate the dewetting of aqueous, evaporating polymer [poly(acrylic acid)] solutions cast on glassy hydrophobic (polystyrene) substrates. As in ordinary dewetting, the evaporating films initially break up through the nucleation of holes that perforate the film, but the rapidly growing holes become unstable and form nonequilibrium patterns resembling ... ... hiện toàn bộ

The equation of state and heat of fusion of poly(ether ether ketone)Abstract The pressure‐volume‐temperature properties of poly(ether ether ketone) (PEEK) were studied experimentally at temperatures of 400°C and pressures to 200 MPa. Specific volume data were fitted successfully to the empirical Tait equation for T < T g and T >... ... hiện toàn bộ

Gravimetric study of high‐pressure sorption of gases in polymersAbstract A gravimetric method for determining precisely the solubility of gases in polymers at high pressure is described. The solubilities of N2 and CO2 in low‐density polyethylene (LDPE); CO2 in polycarbonate (PC); and N2 , CH4 , C2 H... hiện toàn bộ

Sorption and dilation in poly(ethyl methacrylate)–carbon dioxide systemAbstract Sorption and dilation in the system poly(ethyl methacrylate) (PEMA) and carbon dioxide are reported for pressures up to 50 atm over the temperature range 15–85°C. The sorption isotherms were obtained gravimetrically. The dilation accompanying sorption was measured directly with a cathetometer. At low temperatures the sorption and dilation isotherms were con... ... hiện toàn bộ

Sorption and swelling of semicrystalline polymers in supercritical CO2Abstract The equilibrium sorption and swelling behavior of four different polymers—poly(methyl methacrylate), poly(tetrafluoroethylene), poly(vinylidene fluoride), and the random copolymer tetrafluoroethylene–perfluoromethylvinylether–in supercritical CO2 —are studied at different temperatures (from 40 to 80 °C) and pressures (up to 200 bar). Swe... ... hiện toàn bộ

Electronic structure and electrical properties of interfaces between metals and π‐conjugated molecular filmsAbstract The field of organic thin films and devices is progressing at an extremely rapid pace. Organic–metal and organic–organic interfaces play crucial roles in charge injection into, and transport through, these devices. Their electronic structure, chemical properties, and electrical behavior must be fully characterized and understood if the engineering and contr... ... hiện toàn bộ
