Abstract
U ovom radu ispitivane su mješavine poli(metil-metakrilata) i celuloznog acetata, PMMA/CA. Pripremljeni su tanki filmovi čistih komponenata PMMA i CA te polimerne mješavine PMMA/CA sa različitim masenim udjelima CA: 5 % CA (CA5), 10 % CA (CA10) i 20 % (CA20) kako bi se ispitao utjecaj dodatka određene količine CA na svojstva dobivenih uzoraka. Korištene tehnike karakterizacije su termogravimetrijska analiza, diferencijalna pretražna kalorimetrija, infracrvena spektroskopija, pretražna elektronska mikroskopija; određen je kontaktni kut te barijerna i mehanička svojstva uzoraka. Rezultati su pokazali bolja toplinska i mehanička svojstva čistog CA u odnosu na PMMA, međutim, dodatak određene količine CA u polimerne mješavine nije pridonio značajnijem poboljšanju toplinskih i mehaničkih svojstava mješavina. Priređene folije pokazuju porast hidrofilnosti s porastom udjela CA što je vjerojatno posljedica razlika u hrapavosti površine, s obzirom da istovremeno folije mješavina ne pokazuju povećanje propusnost spram vodene pare.
Abstract (english)
In this study, blends of poly(methyl methacrylate) and cellulose acetate, PMMA/CA were tested. Thin films of pure PMMA, CA and PMMA/CA polymeric blends with different mass ratio of CA: 5 % CA (CA5), 10 % CA (CA10) and 20 % (CA20) were prepared to test the effect of adding a certain amount of CA on properties obtained samples. The used characterization techniques are thermogravimetric analysis, differential scanning calorimetry, infrared spectroscopy, scanning electron microscopy; the contact angle and the barrier and mechanical properties. The results showed better thermal and mechanical properties of pure CA compared to PMMA, however, the addition of certain amount of CA into polymer blends had no a significant effect on improving the thermal and mechanical properties of the blends. The hydrophilicity of blends increased with increasing ratio of CA, which most likely resulted from the difference regarding the surface smoothness, having in mind that foils prepared from blends did not show better barrier properties against water vapor, at the same time.
