Description
David Castro and co-authors tune the charge balance in films made from chitosan and a modified cassava starch, in work from twenty twenty-five. Such plant based films could shield food with less plastic waste. Plain mixes are weak and soak up water, which limits use.
Pairing the two oppositely charged polymers forms a tighter complex with smoother structure. Films were cast at a mild acidity and checked by microscopy, spectra, heat tests, and stretch tests. The complex films proved two to four times stronger than plain mixes and stretched a bit farther. They also dissolved far less in water, gut like fluid, and salt buffer. The best mix sat near a charge ratio of one.
