Abstract
U ovom radu je istražen utjecaj molarne mase polielektrolita na formiranje i svojstva polielektrolitnog višesloja poli(alilamin-hidroklorida) i poli(akrilne kiseline). U te svrhe filmovi su pripravljeni s različitim kombinacijama molarnih masa polielektrolita sloj po sloj metodom na površini silicijeva supstrata pri različitim eksperimentalnim uvjetima kako bi se utjecalo na konformaciju polimernih lanaca. Elipsometrom je praćena debljina filma tijekom njegove priprave, a mikroskopom atomskih sila je određena morfologija, hrapavost i poroznost površine filma. Iz dobivenih podataka utvrđeno je da se povećanjem molarne mase polielektrolita povećava debljina filma ako je barem jedan polielektrolit u globularnoj konformaciji. Pokazano je da molarna masa polielektrolita nema značajni utjecaj na debljinu i hrapavost filma ako su oba polielektrolita u izduženoj konformaciji. Otkrivena su i dva nova načina priprave ultra-tankih filmova (d ≈ 2 nm) s poli(akrilnom kiselinom) male molarne mase.
Abstract (english)
In this study the influence of the polyelectrolyte molar mass on the formation and properties of poly(allylamine hydrochloride)/poly(acrylic acid) polyelectrolyte multilayer was investigated. For these purposes, films were prepared on the silicon substrate using layer by layer method with different combinations of polyelectrolyte molar masses under different experimental conditions in order to influence the conformation of the polymer chains. The thickness of the film was monitored during its preparation with an ellipsometer and the morphology, roughness, and porosity of the film surface were determined with an atomic force microscope. From obtained data, it was established that by increasing the polyelectrolyte molar mass, the thickness of the film increases if at least one polyelectrolyte is in globular conformation. On the other hand, if both polyelectrolytes are in an elongated conformation, the polyelectrolyte molar mass has no significant influence on the thickness and roughness of the film. Also, two new ways of preparation of ultra-thin films (d ≈ 2 nm) were discovered by using poly(acrylic acid) of low molar mass.
