This work focuses on the development and evaluation of different methods to increase durability through the development of a highly heterogeneous membrane system comprising a reinforcing component, radical scavenger and/or hydrogen peroxide decomposition catalyst and in which the architecture of the membrane is designed at the nano- to micro-metric length scales, the latter facilitated by the use of solution casting processes. Electrospun nanofibres provide mechanical strength, ensure low membrane swelling when exposed to humidity cycles, and also provide an appropriate distribution medium for radical scavenging species. This presentation will discuss benefits and remaining challenges associated with efficiency and stability of mechanical and chemical reinforcements.
