Double-Layer Films Based on Furcellaran/Chitosan Complex-Structural and Functional Characteristics of Packaging...

Area of Science:

• Materials Science
• Polymer Science
• Biomaterials

Background:

• Chitosan (CHIT) films are well-documented, but double-layer CHIT-FUR membranes with enhanced properties are less explored.
• Developing advanced biomaterials is crucial for sustainable packaging and drug delivery systems.

Purpose of the Study:

• To create and characterize novel double-layer films using furcellaran (FUR) and CHIT-FUR complexes.
• To investigate the physicochemical, mechanical, thermal, structural, and morphological properties of these films.
• To evaluate the potential of these films for food packaging and pharmaceutical applications.

Main Methods:

• Fabrication of double-layer films using FUR and CHIT-FUR complexes.
• Characterization using Fourier-Transform Infrared (FTIR) spectroscopy and Atomic Force Microscopy (AFM).
• Assessment of physicochemical, mechanical, and thermal properties.

Main Results:

• Successful production of distinct double-layer films confirmed by FTIR and AFM.
• The 9:1 ratio (complex_9:1) demonstrated superior uniformity and performance.
• Films exhibited promising physicochemical, mechanical, and thermal characteristics.

Conclusions:

• The developed double-layer CHIT-FUR films offer unique properties not commonly found in single-layer counterparts.
• The 9:1 complex shows significant potential as a high-performance biomaterial.
• These films could serve as eco-friendly alternatives to conventional plastics in food packaging and as novel materials for medical capsules.
