Abstract
Gelovi, aerogelovi i kserogelovi su tri različita stanja materijala, svako od kojih posjeduje jedinstvena svojstva i primjenu. Aerogel je vrsta posebno poroznog materijala, izuzetno niske gustoće te velike poroznosti. Ističe se po svojim iznimnim izolacijskim svojstvima te velikim specifičnim površinama pa se njegova primjena očituje u području optoelektronike, zrakoplovne industrije, svemirske opreme te u mnogim drugim područjima. Celuloza, prirodni biopolimer koji se nalazi u stjenkama biljnih stanica, ističe se kao izvrstan materijal za sintezu aerogelova. Zbog svoje obnovljivosti, biorazgradivosti te biokompatibilnosti celulozni aerogelovi privlače sve više pažnje, pogotovo u području biomedicine gdje se očituje njihov značajan potencijal. Ovaj diplomski rad daje pregled sinteze i karakterizacije kserogelova i aerogelova na bazi celuloze modificiranih ureom, natrijevim kloridom i magnezijevim kloridom. Karakterizacija ovih modificiranih materijala provedena je raznim analitičnim tehnikama, uključujući pretražnu elektronsku mikroskopiju (SEM), energijski disperzivnu spektrometriju (EDS) te rendgensku difrakcijsku analizu (XRD). Primarni cilj je bio istražiti utjecaj ovih modifikacija kao i metode pripreme gela na veličinu pora, poroznost i skupljanje volumena kako bi se dobio uvid u njihovu potencijalnu primjenu u različitim područjima.
Abstract (english)
Gels, aerogels, and xerogels are three distinct states of materials, each with unique properties and applications. Aerogel is a type of particularly porous material, with extremely low density and high porosity. It stands out for its exceptional insulating properties and high specific surface area, so its application is evident in the field of optoelectronics, the aviation industry, space equipment and many other areas. Cellulose, a natural biopolymer found in plant cell walls, is an excellent material for aerogel production. Due to their renewability, biodegradability and biocompatibility, cellulose aerogels are attracting more attention, especially in the field of biomedicine, where they have a significant potential. This thesis provides an overview of the synthesis and characterization of cellulose-based xerogels and aerogels modified with urea, sodium chloride and magnesium chloride. Characterization of these modified materials was performed using various analytical techniques, including scanning electron microscopy (SEM), energy dispersive spectrometry (EDS), and X-ray diffraction analysis (XRD). The primary objective was to investigate the influence of these modifications as well as the gel preparation method on pore size, porosity and volume shrinkage in order to gain insight into their potential application in different fields.
