The development of environmentally friendly materials is an urgent area in agriculture and industry. New ecofriendly sorbent for cleaning the water surface from oil and oil products (KNOP) was developed. It is produced from a mixture of polyacrylonitrile, polyester and wool fibers, which are a waste of textile production. This sorbent doesn‘t have flowability, which almost excludes its elimination. KNOP structures the liquid hydrocarbon into a three-dimensional compact mass, which can be easily separated and practically does not retain water. Novel protective masks with high bacterial filtration efficiency have been developed. For their design, nonwoven polymeric materials from polypropylene produced by OJSC ―SvetlogorskKhimvolokno‖ (SpanBel, Aquaspan, Meltblown) was used. The developed masks are 3-layered nonwoven fabric (SpanBel – Aquaspan – SpanBel) with upper modified surface layer, which allows to achieve a bacterial filtration efficiency up to 98.6%. Biodegradable composites based on polylactide (PLA) are promising materials for various applications. The developed PLA-based 3D printing rod are of great interest for educational and medical purpose. PLA-based sheets and films with micro- and nano-fillers (thickness – 0.05 -0.6 mm, width – up to 60 cm) can be used for making biodegradable packaging and consumer goods (folders, boxes, etc.). Adding carbon fiber to PLAbased tape can strengthen the parts of complex shape, and adding lignin is important for the coatings exposed to direct sunlight. |
