According to the North Carolina State University website on December 11, the United States North Carolina State University (North Carolina State University, NCSU) researchers from the crustaceans and seaweeds with reinforced structure of the material synthesized biobased polymer composite film, which can be used as an alternative to petroleum-based plastic film.
The researchers used soft dendritic colloids (fibrous colloidal scale materials) made from fibrous chitosan (a bio-based polymer that hardens crab shells) reinforced with agarose membranes (bio-based polymers extracted from seaweed) to prepare high-strength bio-based polymer composite membranes.
The film is approximately four times stronger than ordinary agarose film and also has biodegradable, waterproof, transparent, and antimicrobial properties, allowing it to be used as a sustainable packaging film for food and consumer products.
The researchers said they will further improve the structure of the bio-based polymer composite film as an alternative to chemically synthesized polymer films and achieve large-scale mass production. The findings were published in the journal Cell Reports Physical Science.
This composite film is an alternative to traditional petroleum-based plastic films and is made from bio-based materials that are environmentally friendly. It is characterized by high strength, waterproof, transparency and antimicrobial properties, and is suitable for packaging of food and consumer products.
The development of this composite film is also of great significance in reducing the generation of plastic waste, protecting the environment and promoting sustainable development. If large-scale mass production can be realized, it is expected to be widely used in packaging, medical and other fields, further promoting the process of sustainable development.
