Description
  • Cílem práce bylo zhodnotit vliv nanoplniva Cloiste 30B na migraci změkčovadla DEHP (di-2-ethylhexylftalát) z nanokompozitu na bázi polyvinylchloridu v biotických podmínkách. Testovaným polymerem byl měkčený PVC (interkalární činidlo: DEHP) a nanokompozit z měkčeného PVC obsahující 10 hm% organicky modifikovaného montmorillonitu Cloiste 30. Biologická stabilita fólií PVC a PVC/Cloiste 30B byla sledována v aerobním vodném prostředí za přítomnosti směsné mikrobiální kultury (aktivovaný kal z městské čistírny odpadních vod) a v půdním aerobním prostředí (přírodní kompost dřevního původu). Hodnotícími kritérii biostability byly mikroskopická analýza povrchu, sledován byl váhový úbytek nanokompozitu a biologická spotřeba kyslíku indikující biologický rozklad změkčovadla. Sledovány byly také změny v tahových vlastnostech nanokompozitu. Z dosažených výsledků pak vyplývá jednoznačné zhoršení stability měkčeného PVC přídavkem nanoplniv na bázi Cloiste 30B ve vodném i půdním aerobním prostředí. Což je v rozporu (cs)
  • The aim of the work was to evaluate the influence of nanofiller Cloiste 30B on migration of plasticizer DEHP (di-2-ethylhexylftalate) from nanocomposite based on polyvinyl chloride under biotic conditions. Tested polymer was plasticized PVC (intercalated agent: DEHP) and nanocomposite from plasticized PVC containing 10hm% organically modified montmorillonite Cloiste 30B. Biological stability of PVC foils and PVC/ Cloiste 30B was tested: a) in an aqueous aerobic environment in the presence of mixed microbial culture (activated sludge from the municipal wastewater treatment plant), b) in a soil aerobic environment (a natural compost of wood origin). Biostability evaluating criteria was - a microscopic analysis of a surface - nanocomposite weight loss and a biological oxygen demand indicating biodegradation of plasticizer. Furthermore, the changes in nanocomposite tensile properties were observed. As it follows from the results addition of nanofillers based on Cloiste 30B in both aqueous and soil aerobic
