摘要

Nano-modified glycidyl azide polymer (GAP) energetic binder films were prepared using hydroxylation carbon nanotubes (CNT-OH) as crosslinking agent, GAP as prepolymer and toluene diisocyanate (TDI) as curing agent. Optimization of curing process parameters and relative characterization were carried out at the same time. The tensile strength of binder film rises to 7.2 MPa and the breaking elongation is 375% with w(CNT-OH) of 1%, and R of 1.4. The results of thermal gravimetric analysis (TGA) show that the decomposition temperature of azide group and polymer backbone are both increased when carbon nanotubes was introduced into crosslinked network. Therefore the thermal stability of binder film is improved as well. Differential scanning calorimetry (DSC) results show that glass transition temperature (T_g) is below -40°C when w(CNT-OH) equals 1%.
