Title of the PhD project:
Extraction of cellulose nanocrystals or nanofibers from waste lignocellulosic biomass with potential protective properties for textile and/or bio-composite applications
Abstract of the PhD project:
The aim of the project is to extract cellulose nanocrystals or nanofibres from waste lignocellulosic biomass (like hemp, asclepia, kapok, kenaf and others, including biomass co-products and by-products derived from their collection) and use the nanocrystals and nanofibres as coating for textiles. Combination of the nanocrystals with other bio-based active molecules to enhance protection properties of the coating is a goal of the project. The research activity will be carried out at the Department of Chemistry and Industrial Chemistry, Grenoble INP and Pangaia- Grado Zero srl.
