Recently, researchers at Pennsylvania State University in the United States have developed a cheap biomaterial that can be used in the packaging of renewable and alternative plastic packaging insulation, the researchers also developed many other applications of the material, they predict that this New materials will significantly reduce pollution.
The fully degradable polysaccharide electrolyte composite consists of almost equal amounts of cellulosic pulp and chitosan treated with wood, cotton, chitosan, etc. Chitosan is derived from chitin, which is an arthropod and carapace The main component of the exoskeleton; chitin is mainly derived from lobster, crabs and residual shell after people eat shrimp.
The material is unexpectedly powerful. Its insoluble adhesion is useful for product packaging and other applications, such as making better-performing, completely natural lignocellulosic composites, even on the floor. " Jeffrey Catchmark, a professor and principal investigator of agricultural and biological engineering at the Pennsylvania State University, said the eco-friendly barrier coatings range from waterproof papers to ceiling tile and wall coatings to food coatings for preservation.
He explained that the sturdy, long-lasting bond between carboxymethylcellulose and chitosan is key to the performance of the material. The two very cheap polysaccharides have different kinds of molecules that stick together Charge, which is the composite manufacturing impermeable film, coating, adhesives, etc. laid the foundation.
A recent study published in "Green Chemistry" showed that the polysaccharide electrolyte composite coating performed well and that the board made of nanostructured fiber particles of carboxymethylcellulose and chitosan has a strong oil-water barrier property The coating not only resists toluene, n-heptane and salt solutions, but also enhances mechanical properties in dry and humid environments as well as barrier properties to water vapor.
