Abstrak

Synthesis of Fuel Cell Membrane: Copolymerization of Styrene on ETFE Film by Grafted pre-Irradiation. PreirradiationGrafting styrene monomer on ETFE film has been prepared. Research has been performed by γ-ray radiationat various total dose from 2.5 - 12.5 kGy and various dose rate from 1.3 - 1.9 kGy/hour. Irradiated copolymer is thengrafted by styrene monomer in various solvent: ethanol, 2-propanol, and toluene, various concentration from 20 - 70%volume, various temperature from 50 - 90oC, and various grafting time from 2 - 12 hours. The results showed thatpercent of grafting is increase with increase of total dose and decrease of rate dose. The optimum experiment conditionsare obtained at total dose 10 kGy, dose rate 1,9 kGy/hour, 2-propanol solvent, 40% volume styrene, 4 hours graftingtime, and 70oC grafting temperature.
