Abstract:
In this work, polyethylene terephthalate (PET) substrate was treated using KOH solution and was modified using hybrid O-I coating containing polycaprolactone (PCL) as organic phase and tetraethoxysilane (TEOS) as inorganic phase. The coating was prepared through sol-gel process andapplied on the surface by dip coater. Then, electrically conducting polythiophene (PTh) nanoparticles were deposited on the surfaces using chemical deposition method. A facile and rapid chemicaloxidative deposition method using a binary organic solvent system during 12 min of reaction time wasused and the effect of surface modification by hybrid coating on morphology of PTh nanoparticles were studied. The synthesized hybrid layer is transparent and its constitutes are tunable, so, the hybridlayer is susceptible for wide range of application. The optical transparency of PTh nanoparticles coatedon PET films characterized by UV-V is spectroscopy. Field-emission scanning electron microscopy (SEM) and laser particle-size analysis were used to study surface morphology, average size and sizedistribution of PTh nanoparticles. Electrical conductivity of PET substrate deposited by PTh nanoparticles was measured using four probe to be 1.7×10-5 S/cm
