title: Preparation of the poly(arylene sulfide sulfone)/multi-walled carbon nanotubes composites via in situ polymerization.
abstract: The nanocomposites of Multiwall carbon nanotubes (MWNTs) and poly(arylene sulfide sulfone) (PASS) were prepared via in situ polymerization. The compounds were found to distribute uniformly and had excellent thermal properties with glass transition temperatures (T(g)) of 222-224 degrees C and initial degradation temperature (T(d)) of 437.7-445 degrees C. They had better solubility and could dissolve in strong aprotic solvents such as N-methyl-2-pyrrolidone (NMP), dimethylformamide (DMF), dimethyl sulfoxide (DMSO) and so on. After acidification and fluobenzene-functionalization treatment, the MWNTs and polymer matrix via in situ polymerziation showed better compatibility than the composite mixing directly. Additionally, the composites prepared via in situ polymerization had good electrical conductivity of 10(14)-10(7.6) omega x m and mechanical properties with Young's modulus of 0.63-1.08 GPa.
