| Abstract: | The forming technics of interpenetrating polymer networks and its gradient systems based on polyurethane matrix are determined using IR techniques by simultaneous polymerization.The TEM results show that the phase range of materials thus obtained are in nanometer scale.Furthermore,the composites of IPNs blends with Barium Titanate fibers are gained and the conductive and mechanical properties are studied in details. |
