Resumo(s): | The development of multifunctional sustainable polymer composites is an increasing need in the scope of the Internet of Things (IOT) and the circular economy paradigm. In this context, nanocomposites based on Silk Fibroin (SF) and Indium Tin Oxide (ITO) (up to 40%wt) were produced by solvent casting to improve the mechanical and dielectric properties of the protein and develop capacitive touch sensing devices. Samples with good fillers dispersion, compact morphology and optical transparency were obtained, independently of the filler content. The structural conformation of ITO/SF nanocomposites, mechanical and dielectric properties are dependent on ITO content, the dielectric constant reaching values up to 10 for an ITO content of 40 wt.%. On the other hand, the samples thermal transitions are independent of the filler amount. ITO/SF nanocomposites with 10 wt.% ITO content were used for a capacitive touch sensor development. The excellent sensing behavior and reproducibility of the device demonstrates the suitability of the developed silk fibroin-based nanocomposites for sustainable electronic approaches |
