Abstract

Examination of mechanical and solvent transport properties of π-conjugated polymers (PCPs), viz;poly(2-nitro-p-phenylene-1,3,4-oxadiazole) [PNPO], poly(p-phenylenevinylene-1,3,4-oxadiazole) [PPVO], poly(p-(nitrophenylene)vinylene-1,3,4-oxadiazole) [PNPVO], poly[(2-N,Nʹ-dibutylaminophenyl)1,3,4-oxadiazole] [PNAPO], poly[pyridine(2-nitrophenyl)-1,3,4-oxadiazole] [PPNO] and poly[2-(o-nitrophenyl)-5-phenyl-1,3,4-oxadiazole] [PNPPO] has been done in flexible film form after blending them with poly(methylmethacrylate) or polystyrene. All six PCPs, in blended form, showed good mechanical properties with tensile strength in the range of 11.45 MPa - 22.89 MPa. Loading of TiO2 nanoparticles onto selected polymer matrices has been found to contribute to a quantum enhancement in tensile properties. Solvent transport studies of blended polymer films and selected TiO2 loaded matrices were carried out. Surfaces of films have been found to be predominantly hydrophobic ensuring a long service life for the appliances derived from them in moisture rich ambience.
