Development Of New Green Chitosan-Natural Rubber And Chitosan-Banana Trunk Fibres Biocomposites As Release Matrices

A new class of green biocomposites comprising of (i) acidified chitosan (CTSAC) dispersed in partially cross-linked NR matrices ( AC-d-NR) = 2.5, 5, 10, 20 and 40-phr, and (ii) banana trunk fibres (BTF) immobilized in CTSAC (BTF-i-CTSAC) were prepared and characterized by means of Fourier Transform...
