Abstract
Svrha ovog rada je pripremiti kompozite polilaktid/klinoptililot metodom izlijevanja filma i istražiti utjecaj klinoptilolita na svojstva polilaktida (ponašanje u vodi i toplinska razgadnja). Pripremljeni su filmovi kompozita PLA/klinoptilolit u kloroformu s 0, 2, 4, 6, 8 i 10 % klinoptilolita. Analizom FT-IR spektara potvrđen je zaostatak otapala u kompozitima. Primjenom neizotermne termogravimetrije istraživan je utjecaj klinoptilolita na toplinsku postojanost PLA. Rezultati su pokazali da dodatak klinoptilolita poboljšava toplinsku postojanost polilaktida. Kompoziti PLA/klinoptilolit su držani u vodi 5 dana kako bi se utvrdilo dolazi li do procesa apsorpcije vode ili hidrolize polilaktida. Pretpostavlja se da je kod svih kompozita došlo do hidrolize polilaktida, a kod kompozita sa 6 i 8 % klinoptilolita došlo je i do apsorpcije vode.
Abstract (english)
The purpose of this thesis is to prepare polylactide/clinoptilolite composites by the film casting method and to investigate the influence of clinoptilolite on the properties of polylactide (water behavior and thermal decomposition). Films of PLA/clinoptilolite composites in chloroform with 0, 2, 4, 6, 8 and 10 % clinoptilolite were prepared. Solvent residue in the composites was confirmed by FT-IR spectrum analysis. The influence of clinoptilolite on thermal stability of PLA was investigated using non-isothermal thermogravimetry. The results showed that the addition of clinoptilolite improves the thermal stability of polylactide. PLA/clinoptilolite composites were kept in water for 5 days to determine whether a process of water absorption or hydrolysis of the polylactide occurred. It is assumed that polylactide hydrolysis occurred in all composites, and water absorption occurred in composites with 6 and 8 % clinoptilolite.
