- Abstract
The nonisothermal crystallization investigation on different contents of graphene filled PEEK nanocomposites by ball milling and solution dispersed was performed on differential scanning calorimetry. Jeziorny and Mo's methods were selected to evaluate the result, so as to investigate the nonisothermal crystallization kinetics of pure PEEK and two kinds of PEEK/GE nanocomposites. Mo's method was demonstrated to be the most appropriate model to represent the crystallization behavior for neat PEEK and PEEK/GE nanocomposites under nonisothermal condition. The result showed that the absolute degree of crystallinity of both PEEK/GE nanocomposites decreased with increasing the content of graphene, but increased the nucleation activity for the nanocomposites. When the addition of graphene was 1 wt%, the dispersed method affected the crystallization mechanisms obviously, either promoting or hindering the polymer matrix crystallization. Overall, the method that filling graphene to PEEK matrix had influence on the nonisothermal crystallization process, hence affected the properties of nanocomposites.
