Abstract

Cilj magistrske naloge je bil izdelava in testiranje vseceluloznih kompozitov iz celuloznih vlaken in nanofibrilirane celuloze. Za izdelavo kompozitov smo uporabili tri unikatne metode, ki so bile plod preliminarnih testov. Pri papirniški metodi, smo celulozno maso in nanofibrilirano celulozo zmešali in iz zmesi formirali kompozit, med tem ko smo pri metodi z lijem in metodi s filmi nanocelulozo nanašali na že narejene celulozne liste. Pri papirniški metodi je šlo torej za izdelavo homogenega kompozita, med tem ko smo pri drugih dveh metodah nanocelulozo nanesli le na površino. Z vsako metodo smo izdelali kompozite z različnimi dodatki nanoceluloze ter tako preverili vpliv dodatka na mehanske lastnosti in poroznost kompozita. V analitskem laboratoriju smo kompozitom izmerili gramaturo, debelino, utržno jakost, poroznost in permeabilnost ter raztržno odpornost. Rezulate smo premerjali glede na dodatek nanoceluloze in med samimi metodami.

Secondary title: Mechanical properties and porosity of biobased composite from woody cellulose fibers and nanofibrills
Secondary abstract: The goal of this research was to produce and test all cellulose composites from cellulose fibres and nanofibrilated cellulose. For the production of the composites we used three unique methods which were the result of extensive preliminary tests. The papermaking method was based on mixing cellulose fibres with nanofibrilated cellulose and forming a composite on the mesh, while the funnel and film method used already made cellulose sheets and coated them with nanofibrilated cellulose. For every method we made composites with different contents of nanofibrilated cellulose and tested its impact on the mechanical properties and porosity. We measured the grammage, thickness, tensile strength, porosity and tear resistance. The results were compared based on the amount of additive and method used.
