Antibacterial and anti-inflammatory green nanocomposites

This work deals with the production of a green technology membrane to produce drinkable water from polluted fresh water resources disseminated in rural area, that is by using a small and compact water purification plant. The material adopted for this purpose is non woven-tissue based on green nanocomposites of Chitin Nanofibrils (CN) bonded with nano silver and electrospun with chitosan and polypeptides. Nonwoven materials obtained as electrospun of a blending of nanochitin fibrils and lignin, by using polyethylene oxide as solvent. The adopted blend was carefully prepared as sol-gel material at suitable temperature, mixing conditions and time of ageing. The non-woven tissue was produced by means of a pilot scale electrospinning machine model Nanospider NS LAB 500 supplied by Elmarco. Very uniform membrane with a diameter less than 150 nm were produced. Stress tests showed a good resistance of multiple layer samples.
