Resumo
Anion exchange fuel cells (AEMFC) have attracted widespread attention in the last years
and are considered one of the most promising environmentally friendly power generations.
An auspicious way to produce well-controlled structures for applications as anion exchange
membrane is using the radiation-induced grafting method (RIG) with RAFT agents [1]. RAFT
consists of a reversible addition fragmentation chain transfer of free radicals and allows the
control over polymeric molecular weight and copolymer topology and other properties.
Ethylene tetrafluoroethylene (ETFE) is a type of fluoropolymer that can be applied in AEM
due to its lightweight, excellent chemical and thermodynamic stability, and greater
resistance to radiation ageing [2]. In this study, we investigated the beneficial outcomes of
performing the ETFE-AEM synthesis in a fully controlled manner by RAFT polymerization
using RIG. The influence of RAFT agent on physical (mechanical behavior, dimension),
chemical (such as IEC), thermal properties (TGA and DSC) were investigated in detail for
future and evaluated in AEMFCs. ETFE-grafting-Vinylbenzyl chloride (VBC) using RAFT
agent controlled grafting degree of membrane and improved mechanical properties
compared to conventional method of grafting.
