Chitosan, the polymer of the future

Nowadays it’s hard to imagine human life without polymer compounds. Currently, they’re obtained from petroleum products and at the same time, due to the instability of chemical and biological influence, it causes ecological problems. Biodegradable polymers are being created to solve those problems. Our work is dedicated to the creation of biodegradable polymers from renewable supplies such as chitin. We have prepared a membrane from it and studied the properties of the membrane and its biodegradation under the influence of external factors. A chitosan membrane can be used for food packaging, because it has antibacterial and antifungal properties, meaning it extends the shelf life of food.
