Abstract
- The aim of research was to develop biopolymer films based on natural polysaccharides. For the first time, biodegradable films were obtained on the basis of a furcellaran-chitosan polyelectrolyte complex. The conditions for its formation were determined by measuring the zeta potential as a function of colloid pH, the size of pure components and their mixtures. The structure and morphology of the prepared films were characterised by FT-IR and AFM analysis. The lowest WVTR values were observed for the FUR and the CHIT-FUR films at the ratio of 9:1. The mechanical, water and rheological properties depend on the weight ratio of furcellaran to chitosan in the mixture. The thermal stability has been improved in CHIT-FUR films at the 9:1 ratio. The results obtained create the possibility of successfully using CHIT-FUR films in the development of biodegradable packaging materials.<br /> (Copyright © 2021 The Authors.
