Abstract

Non-isothermal crystallization of aluminum nanopowder-filled poly(3,3-bis-azidomethyl oxetane) (PBAMO) from melt at various constant cooling rates from 1 to 10°C min-1 was studied. Ozawa's approach was used to analyze non-isothermal crystallization kinetics. It was found that Ozawa's approach was effective at medium constant cooling rate. The crystallization activation energy derived from Kissinger's equation was 80.8 kJ mol -1. The experimental results showed that the aluminum nanopowder acted as a nucleating agent to raise the peak crystallization temperature and to accelerate the crystallization rate at higher constant cooling rates. Uniform crystals which showed one melting peak could be obtained at a constant cooling rate of 1°C min-1.
