Preparation and characteriz ation of po ly(۳- methylthiophene)/SiO۲ na nocomposites: Chemical oxi dative met hod in bi nary organic solvents

Poly(۳ -methylthio phene) (P۳MTh),due to the pre sence of la teral CH۳ group, shows a significant increas e in solubility, fusibility, and lumi nescence compared to polythiophene [۱].In ۲۰۱۰, the idea of utilizing binary miscible organic solve nts was proposed for pure polythiophene by S.S. Jean et al. [۲]. This succes sful route can be generalized toP۳ MTh synthe sis as well. In thepre sent work,this new st rategy has been employed to prepare P۳MTh/SiO۲nanocomposites using chloroform/acetonitrile binary solvents. At first, a homogenized an d stabilized nanofluidis prepared with nan o-SiO۲pow der and so dium dodecylbenzenesulfonate (SD BS) or so dium poly(s tyrene sulfonate) (SPS S) stabilize rs in chloroform by sonication. N ext, ۳-meth ylthiophene and the highly concen trated solution of oxida nt in acetonitrileare adde d to this na nofluid.
