摘要

Nylon 66/mesoporous molecular sieve (pore diameter: 2.7 nm) composites were prepared by annealing mixtures of nylon 66 and mesoporous molecular sieve (FSM) powders under high pressures and high temperature (FSM content:0-60 wt %;pressure:0.5-30 MPa;temperature: 300 deg C;time: 1 h).X-ray diffraction and TEM measurements indicated the presence of the pores of FSM in the composite.Above 2 MPa,nylon 66 was charged in the pores of FSM.The fraction of the charged nylon 66 increased with pressure and was independent of the FSM content (pressure:2-30 MPa;fraction of charged nylon 66:54-66%).The infrared spectrum of the composite showed the bands based on Si-O,C-H,N-H,C=O.DSC measurement indicated that the heat of fusion of nylon 66 crystallite in the FSMpores was low compared with that of nylon 66.The composites prepared above 2 MPa were found to be superior in storage modulus to nylon 66.The modulus increased with an increase in the fraction of charged nylon 66 and the amount of FSM.
