ENGINEERED HYBRID ORGANIC-INORGANIC THERMOPLASTIC MATERIALS: CRYSTALLIZATION KINETICS AND TENSILE PROPERTIES

摘要

The nonisothermal and isothermal crystallization kinetics of low-density polyethylene (LDPE) and polypropylene (PP) in phosphate glass (Pglass)-polymer hybrid materials were studied by way of differential scanning calorimetry (DSC). The kinetics was described using the Avrami equation. The percent crystallinity decreased with increasing Pglass concentrations. The half time for crystallization decreased significantly while the propagation rate constant increased with increasing Pglass concentrations in the hybrids. Tensile modulus increased and the energy to break decreased with increasing Pglass concentrations up to 40% Pglass in the hybrids.
