Cross-linked chitosan/tannin extract as a biodegradable and repulpable coating for paper with excellent oil-resistance, gas barrier and UV-shielding

A new study shows chitosan-/tanninextract based epoxy as biodegradable and recyclable coating for paper - with excellent water, oil and UV-aging resistance

A series of cross-linking copolymers of chitosan and tannin extract-based epoxy (CS/xTE, x = 0.125, 0.25, 0.5 and 1) were designed and synthesized…
