Waste created by technology products increases more and more and, unfortunately, it is very polluting. To solve this issue, a team of researchers at the University of Missouri-Columbia led by Professor Suchismita Guha, in collaboration with scientists at the Federal University of ABC in Brazil, focused their attention in the research of natural materials that can replace the traditional ones. The goal is to get biodegradable displays on the basis of some organic structures consisting of peptides or proteins which can be assembled into particular nanostructures to be used as models for other materials.
To reach the realization of displays for smartphones and tablets these structures must then be combined with polymers that emit blue, green and red light. When the study will be completed it will be possible to buy 'green' devices with biodegradable components.
The research, called 'Self-Assembled Peptide-Polyfluorene Biodegradable Nanocomposites for Organic Electronics', has been financially supported by the National Science Foundation and by CNPq (Conselho Nacional de Desenvolvimento Científico and Tecnológico).
