Degradability of organic-inorganic cellulose acetate butyrate hybrids in sea water

Abstract

Environmental degradability of novel organic-inorganic cellulose acetate butyrate hybrids obtained via solgel process was investigated. The degradation of hybrids was studied under marine exposure conditions in the Baltic Sea for a period of 25 weeks. The influence of characteristic parameters of sea water on the degree of degradation monitored by changes of weight and optical microscopy was discussed. The degraded samples were also examined by FT-IR spectroscopy. It has been established that the CAB/silica hybrids are more susceptible to biodegradation in sea water environment than pure cellulose acetate butyrate.

The Effect of Concentration and Type of Plasticizer on the Mechanical Properties of Cellulose Acetate Butyrate Organic-Inorganic Hybrids

“…In our previous work we examined the effect of inorganic phase amount and diethyl phthalate and citrate plasticizer on the degradability of organic-inorganic cellulose acetate butyrate films in sea water [34]. The results of our study showed that the higher the amount of silica incorporated into the CAB with the DEP plasticizer, the higher degradability of the samples.…”

Degradation of Cellulose Derivatives in Laboratory, Man-Made, and Natural Environments

“…After 25 weeks of incubation in seawater, organic−inorganic hybrid CAB with 6% TEOS and 25% DEP or 12% TEOS and 25% DEP lost 17% and 18% of their weight, respectively, while CAB modified with only DEP lost 12%. 75 The incorporation of CNF in polylactide films increased the otherwise slow degradation of polylactide in the simulated marine environment at 25 °C with periodic fluorescent illumination. 76 916 seawater samples illustrated that oceanic microfibers in a large part consisted of cellulosic fibers.…”

“…Siła wzajemnych oddziaływań jest istotna ze względu na potencjalne kierunki zastosowań funkcjonalnych materiałów oraz ich trwałość. Obecność silnych i trwałych połączeń powinna ograniczyć ryzyko migracji czy dekompozycji, co ma najistotniejsze znaczenie dla utrzymania jakości, a także zapewnienia bezpieczeństwa ich stosowania (Drisko i Sanchez, 2012;Kickelbick, 2007;Krasia--Christoforou, 2015;Romero i Sanchez, 2004;Wojciechowska i Foltynowicz, 2009;Wojciechowska, Heimowska, Foltynowicz i Rutkowska, 2011;Wojciechowska, Foltynowicz i Nowicki, 2013a;Wojciechowska, Foltynowicz i Nowicki, 2013b;Wojciechowska, Pietras i Maciejewski, 2014).…”
