The estimation of environmental degradability of different ramie fibre reinforced biocomposites in Baltic Sea water and in compost with activated sludge under natural conditions is the subject of this paper. The characteristic parameters of environments were monitored during incubation time and their influence on the rate of degradation of biocomposites was discussed. The degradation processes of...
Przedstawione badania obejmowały degradację środowiskową materiałów polimerowych (skrobi termoplastycznej, celulozy modyfikowanej oraz dwóch typów kompozytów skrobiowo-celulozowych) w Morzu Bałtyckim przy Nabrzeżu Norweskim w Gdyni. Degradację prowadzono również w warunkach laboratoryjnych w wodzie morskiej z dodatkiem eliminującego działanie mikroorganizmów azydku sodu (NaN3), co umożliwiło ocenę...
Przedstawiono wyniki badań degradacji środowiskowej niemodyfikowanego i modyfikowanego za pomocą amorficznego poli[(R,S)-3-hydroksymaślanu] (a-PHB) poli(D,L-laktydu) (PLA), w warunkach naturalnych - w pryzmie kompostowej z osadem czynnym bądź w wodzie Morza Bałtyckiego. Podczas degradacji kontrolowano zmiany kilku ważnych charakterystycznych parametrów obydwu tych środowisk. Proces degradacji PLA...
The comparison of degradation of modified poly(e-caprolactone) film in different environments is presented. Poly(e-caprolactone) was incubated in a natural environment ± sea water (the Baltic Sea), in buffered salt solution, in liquid medium containing sea water with NaN3 and in compost with plant treatment activated sludge (under natural and laboratory conditions). The characteristic parameters of...
The subject of this work is the degradation of pure polyethylene and modified polyethylene films containing 5% and 8% starch, and polyethylene with pro-degradant additives in the form of "master batch" in amounts of 20%. The degradation of polymer samples was studied under marine exposure conditions in the Baltic Sea. The experiment was also performed in laboratory at the ambient temperature,...
