Cellulose phosphorylation optimisation for a transparent flexible substrate for battery-free antennas
Fedrigoni’s role in the MADRAS project is to produce a transparent flexible substrate for the development of a geotracking battery-free flexible tag. Fedrigoni opted to produce the substrate based on cellulose materials and, more precisely, phosphorylated cellulose nanomaterials. According to literature, cellulose phosphorylation is mainly carried out by reacting cellulose with urea and phosphoric acid.…
