| dc.description.abstract | A number of nanoclay/poly(methyl methacrylate) (PMMA) composite films were prepared with three different clay concentrations (0.5 %, 1 % and 2 % (w/%)) via a solution-casting process. The nanoclay was modified by applying different compatibilization techniques: mere silane surface treatment and surfactant application with the addition of a silane agent. The interlayer distances of the clay galleries were determined using X-ray diffraction (XRD) and the modifications were verified with Fourier-transform infrared spectroscopy (FTIR) analysis. The dynamic mechanical analyses (DMA) were performed to clarify the viscoelastic properties of the produced films. Morphological characterizations were carried out with a scanning electron microscope (SEM). The neat clay/PMMA composites and pure PMMA film were also used to compare the effects of the compatibilization methods. The silane-modified clay/PMMA composites exhibited the best performance, as compared to neat PMMA, by considering the storage modulus (17.7 % increase) and the glass-transition temperature (20 % increase). However, in terms of the dynamic mechanical properties, the joint implementation of these two modification techniques did not satisfy the expectations, probably due to the excess modifier and the plasticizing effect. © 2019 Materials and technology.; Avtorji so s tako imenovanim raztopno-ulivnim procesom pripravili {tevilne kompozitne filme (tanke prevleke) na osnovi nanogline/polimetil metakrilata (PMMA) s tremi razli~nimi koncentracijami gline (0,5, 1 in 2 masnih dele`ev). Nanoglino so modificirali z razli~nimi kompatibilizacijskimi tehnikami: s povr{insko obdelavo s silanom (SiH4) ter z aplikacijo povr{insko aktivne snovi z dodatkom za tvorbo silana. Razdalje med galerijami plasti gline so dolo~ili z rentgensko difrakcijo (XRD) in modifikacije so verificirali z infrarde~o spektroskopijo s Fourierjevo transformacijo (FTIR). Dinami~ne mehanske analize (DMA) so izvedli, da bi razjasnili viskoelasti~ne lastnosti izdelanih filmov. Morfolo{ke lastnosti filmov pa so okarakterizirali z vrsti~nim elektronskim mikroskopom (SEM). Med seboj so primerjali izdelane kompozite glina/PMMA in ~isti PMMA ter s tem ugotavljali u~inkovitost kompatibilizacijskih metod. S silanom modificirani kompoziti glina/PMMA ka`ejo bolj{e lastnosti v primerjavi s ~istim PMMA; meritev modula shranjene energije je pokazala 17,7 % izbolj{anje in temperatura prehoda v steklasto stanje se je povi{ala za 20 %. Vendar pa implementacija obeh tehnik modifikacije z vidika dinami~nih lastnosti ni izpolnila pri~akovanj, verjetno zaradi prebitka modifikatorja in u~inka plastificiranja. © 2019 Materials and technology. | |
