Abstract
Ovaj rad opisuje karakteristike hidrofilno modificiranih silikona. Ukratko je opisano što su silikoni, kako se dobivaju i imenuju, te njihova svojstva i gdje se oni primjenjuju. Za izvođenje eksperimentalnog dijela korištena su dva uzorka silikona: LK-Ag-Platinum i LK- 7300 koji su dobiveni od tvrtke ELKAY SILICONES. Određivala se viskoznost otopina silikona različitih koncentracija. Analiza uzoraka izvršila se FTIR-spektroskopijom. Iako je FTIR analiza pokazala da su ispitivani uzorci gotovo identični, odnosno da posjeduju iste funkcionalne skupine, uočeno je da se viskoznost ispitivanih uzoraka značajno razlikuje. Pretpostavlja se da se radi o sličnim polimerima, a razlikuju se po molekulskoj masi ili u konformaciji.
Abstract (english)
This work describes the characteristics of hydrophilicaly modified silicones. It briefly describes what silicones are, how to make them and name them, their properties and application. For the experiments, two samples of silicones were used: LK-Ag-Platinum and LK-7300, which were supplied by ELKAY SILICONES. The tests included viscosity measurements for aqueous silicone solutions of different concentrations. Analysis of samples was carried out also by FTIR spectroscopy. Although FTIR analysis showed that the test samples are almost identical, and that they have the same functional groups, it was observed that the sample viscosity is quite different. It can be assumed that the polymers are similar, but they differ in molecular weight or in the conformation.
