Abstract
U ovom radu pripremljene su polimerne mješavine polilaktida (PLA) i polietilena visoke gustoće (HDPE) bez i s dodatkom nanopunila cinkova oksida (ZnO) u različitim omjerima. Zamješavanje polimera i punila provedeno je u Brabender gnjetilici. Na pločicama PLA/PE, PLA/PE/ZnO mješavina pripravljenim na hidrauličkoj preši provedena su ispitivanja površinskih svojstava primjenom metode kontaktnog kuta, toplinskih svojstava primjenom diferencijalno pretražne kalorimerije (DSC), termogravimetrijske analize (TGA), i određivanjem toplinske vodljivosti, mehanička svojstva na mehaničkoj kidalici, i morfologija primjenom pretražnog elektronskog mikroskopa (SEM). Rezultati su pokazali da su PLA i PE nemješljivi polimeri, te da dodatak nano-ZnO ne doprinosi poboljšanju mješljivosti. PE doprinosi porastu toplinske stabilnosti i toplinske vodljivosti PLA/PE mješavina dok nano-ZnO smanjuje toplinsku stabilnost mješavina PLA/PE/ZnO. Sniženje prekidne čvrstoće ukazuje na slabu adheziju između PLA i PE polimera.
Abstract (english)
In this work, polymer blends of polylactide (PLA) and high density polyethylene (HDPE) were prepared without and with the addition of nanofillers of zinc oxide (ZnO) in different ratios. Mixing of polymers and fillers was carried out in a Brabender kneader. Surface properties were tested on PLA/PE, PLA/PE/ZnO blends prepared on a hydraulic press using the contact angle method, thermal properties using differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), and by determining thermal conductivity, mechanical properties on mechanical tearing, and morphology using a scanning electron microscope (SEM). The results showed that PLA and PE are immiscible polymers, and that the addition of nano-ZnO does not contribute to the improvement of miscibility. PE contributes to the increase in thermal stability and thermal conductivity of PLA / PE mixtures while nano-ZnO reduces the thermal stability of PLA / PE / ZnO blends. Decreased tensile strength indicates poor adhesion between PLA and PE polymers.
