3. Cellulose Nanofibril-based Hybrid Materials : Eco-friendly design towards separation and packaging applications
Abstract : Nanocellulose has been lately considered as the “Holy-Grail” in the design of sustainable materials due to its bio-origin and an unprecedented combination of prominent features, including good mechanical properties, anisotropy and versatile surface chemistry. In addition, nanocellulose in the form of cellulose nanofibrils, can adopt variable structures and morphologies depending on the processing technique, such as aerogels, films and monoliths. READ MORE

5. Functional Layer-by-Layer films and aerogels of cellulose nanofibrils
Abstract : This thesis deals with the preparation of functional Layer-by-Layer (LbL) films of cellulose nanofibrils (CNFs) and polyelectrolytes. LbL films ranging in thickness from 10 nm to 5 μm were deposited onto both solid surfaces and porous nanocellulose aerogels in order to prepare functional surfaces and materials. READ MORE
