Chemical structure and compatibility of chitosan and nylon - 6 blends

Nowadays, polymer blending is one of the most effective ways of providing a new and desirable polymers materials. Modification of chitosan by blending with another polymer can be explored further due to its functional groups. In this study, solution blending technique is used to blend chitosan and n...
