Abstract
Abstract
In this study, poly(2-ethyl aniline)/graphene composites were prepared by a mechanochemical method, through in-situ polymerization of 2-ethyl aniline in the presence of graphene at different concentrations. Vickers microhardness, elastic modulus and electrical conductivity measurements were carried out as a function of the graphene concentration in the composite. Increasing the graphene content of the composite resulted in an increase in the conjugation length and carrier mobility of the polymer, and thus in the electrical conductivity of the composites. However, thermogravimetric analysis showed that the thermal stability of poly(2-ethyl aniline) increased with increasing graphene concentration. This study suggests the potential of graphene concentration to efficiently modify the morphological, electrical, mechanical, and thermal properties of poly(2-ethyl aniline).
