| Abstract Scope |
Biological materials offer molecularly encoded structures that can be repurposed as sustainable precursors for functional materials. This talk will discuss the conversion of silk fibroin, a renewable protein-based biopolymer, into ultrathin carbon nanosheets for flexible transparent conducting electrodes. By controlling silk concentration, spin-coating rate, β-sheet stabilization, and pyrolysis temperature, precursor films can be transformed into smooth carbon layers with tunable thickness, graphitic ordering, optical transparency, and electrical conductivity. Structural characterization reveals how thermochemical conversion progressively removes heteroatoms and promotes pseudo-graphitic domains, linking processing conditions to optoelectronic performance. The resulting silk-derived carbon nanosheets combine high transparency, mechanical flexibility, and conductivity while using a bio-derived precursor and catalyst-free processing route. More broadly, this work illustrates how biological polymers can serve not only as structural biomaterials, but also as programmable feedstocks for bioenabled manufacturing of flexible electronic and optoelectronic materials. |
