Abstract: The application describes a polymer matrix that features a polymer mixed with an antimicrobial agent (e.g., a pathogen inactivating material). The polymer can be an ablative or a sacrificial polymer that will degrade over time in either a surface or bulk degradation method. In some embodiments, the polymer matrix can also include a labile molecule built into the backbone of the polymer.

Abstract: A biodecomposable film material includes: a biodecomposable material which is one or more selected from the group consisting of polylactic acid, poly(butylene adipate-co-terephthalate) and poly butylene succinate and which has a mass percentage of 60-70%; a food grade agricultural waste having a diameter smaller than 50 μm and a mass percentage of 10-30%; a modifier which is calcium carbonate powder or magnesium silicate salt powder and which has a diameter smaller than 8 μm and a mass percentage of 7-29%; and an organic decomposing bacterium which is Bacillus amyloliquefaciens. The organic decomposing bacterium is heat resistant bacillus capable of withstanding a temperature of 100° C. and has a mass percentage of 1-3%. The biodecomposable material, the food grade agricultural waste, the modifier, and the organic decomposing bacterium are subjected to compounding and blowing to form a film having a thickness of 40-60 μm.

Abstract: In the present invention, biodegradable nanocomposites are introduced which include nanoclay particles, titanium dioxide nanoparticles, polyethylene, polypropylene, starch as a biopolymer, maleic anhydride and glycerol. The obtained nanocomposites have very high physical, mechanical and antimicrobial properties. Proper dispersion and distribution of nanoparticles in composite substrate would help in improving the quality of the product to a great extent. The presence of polypropylene next to polyethylene would eliminate the weak points of polyethylene/biopolymer composite as polypropylene helps to modify the physical and engineering properties of nanocomposites in the presence of nanoclay. Titanium dioxide nanoparticles have antimicrobial properties and would result in products which are useful for food and pharmaceutical industries. Another important aspect of this invention is the production of samples in one step by reaction extrusion method.
