There are many advantages to using guar gum-chitosan film. Researchers discovered that even after 240 hours, a synthetic cross-linked film remained impermeable to water. When compared to chitosan-only films, it showed a low water vapour permeability.
Key Highlight:
- Scientists in Guwahati have created a polymer that is tough, water-repellent, and durable.
- The cross-linked guar gum-chitosan has greater mechanical strength, water repellency, and resistance to extreme environmental conditions.
Scientists in Guwahati have created a polymer that is tough, water-repellent, and durable.
Scientists at the Indian Institute of Advanced Study in Science and Technology, Guwahati, have created a biodegradable polymer from guar gum and chitosan, both of which are polysaccharides (sugars) derived from guar beans and the shells of crabs and shrimp. This polymer is an excellent packaging material because it is robust, water-repellent, and durable.
Even after 240 hours, the cross-linked film created by the scientists did not dissolve in water, according to the study’s findings.. The mechanical strength of the cross-linked guar gum-chitosan composite film was superior to that of other biopolymers, as well.
Due to its high contact angle of 92.8 degrees, the cross-linked guar gum-chitosan composite film was extremely water-repellent or hydrophobic as well. It. It was less permeable to water vapour than chitosan-based films.
The cross-linked guar gum-chitosan has greater mechanical strength, water repellency, and resistance to extreme environmental conditions, according to an Indian government news release.
