Abstract:V zadnjem času se vedno bolj poudarja pomembnost različnih naravno obnovljivih materialov. Eden pomembnejših je celuloza, ki jo najdemo v različnih rastlinskih virih. Poleg konvencionalnih virov celuloze se v zadnjem času raziskujejo tudi nekonvencionalni, ki so pogosto stranski produkti prehrambnih rastlin v kmetijstvu. V okviru diplomske naloge smo raziskali nekaj rastlin kot potencialnih virov tekstilnih vlaken. Proučili smo koprivo, vrbo, brnistro, velecvetno mrtvo koprivo, lucerno in konopljo. Najprej smo iz stebel izolirali vlakna, ki smo jih okarakterizirali. Izolirana vlakna so imela ustrezne tekstilno tehnološke lastnosti. Izolirana vlakna smo uporabili za pripravo nanokristaline celuloze. Opazovali smo morfološke značilnosti delcev nanokristaline celuloze in določili njihovo velikost. Delci so bili paličaste oblike velikosti med 205nm do 569nm. Določili smo še zeta potencial dispergiranih delce, ki kaže na stabilnost delcev v disperziji.

Title:Preparation and characterization of nanocellulose from different origins
Abstract:Lately is more and more important to go back to nature, to go back to naturally renewable materials. One of the most important natural renewable sources is cellulose, which can be found in many plants. In addition to conventional sources of cellulose recently there are explored also unconventional sources, which are often waste of food crops in agriculture. Within the thesis we studied some plants as potential sources of fibres. We examined the nettle, willow, Spanish broom, big dead nettle, alfalfa and hemp. We first isolated fibres from stems which we characterize. We got relevant textile mechanical properties. Isolated fibres were used to prepare nanocrystalline cellulose. We observed morphological characteristics of nanocellulose particles and determine their size. The particles had rod shape and their size were from 205nm to 569nm. We also determined zeta potential, which showed us that we have stability of particles in dispersion.
Keywords:natural renewable materials, retting of fibres, properties of fibres, nanocellulose
