The talk describes a bio-inspired approach to design and prepare proton conducting materials based on self-assembling short protein sequences (peptides). I will discuss proton transport mechanisms and design principles to improve the conductivity of these materials. I will then demonstrate post assembly processes to tune the proton conductivity further. Finally, I will show materials' stability, biocompatibility, and biodegradability and emphasize the effects of peptide sequence design on these properties. These studies demonstrate the remarkable opportunities of using artificial proteins in developing a new generation of sustainable electronic materials.
The talk describes a bio-inspired approach to design and prepare proton conducting materials based on self-assembling short protein sequences (peptides). The effect of amino-acid side-chain and backbone conformation on proton conductivity of the peptide fibrils will be discussed. We will show that the rational design of peptides can lead to fabrication of novel type of environmentally friendly, high performance, self-assembling, proton conducting materials.
