Abstract
Naizmjeničnom adsorpcijom pozitivnih i negativnih polielektrolita (tzv. sloj-po-sloj metodom) na nekoj površini nastaju višeslojevi. Svojstva dobivenih filmova ovise o eksperimentalnim parametrima poput korištenih polielektrolita, vrste supstrata, ionske jakosti te vrste pozadinske soli. U ovom diplomskom radu je istraženo kako vrsta dvovalentnog kationa utječe na svojstva višesloja pripravljenog od poli(dialildimetilamonijeva klorida) i poli(natrijeva 4-stirensulfonata). Izabrani kationi su Mg2+, Ca2+, Sr2+, Ba2+, Ni2+, Zn2+ i Cu2+ . Elipsometrijom je praćen rast filmova do deset slojeva, a morfologija i površinska hrapavost određeni su mikroskopom atomskih sila. Tenziometrijom je praćena promjena močivosti površine prilikom adsorpcije svakog polielektrolitnog sloja. Dobiveni rezultati ukazuju da kod kationa zemnoalkalijskih metala postoji ion-specifični efekt koji nije uočen kod kationa prijelaznih metala. Tako su debljine, hrapavosti i močivosti filmova priređenih uz katione prijelaznih metala slične, dok se ova svojstva međusobno razlikuju za višeslojeve priređene uz katione zemnoalkalijskih metala.
Abstract (english)
Polyelectrolyte multilayers are formed by alternating adsorption of polycations and polyanions on a surface (layer-by-layer method). The properties of the film depend on the experimental parameters such as used polyelectrolytes, type of substrate, ionic strength and type of the background salt. In this thesis it was investigated how the type of divalent cation affects the multilayer prepared from poly(diallyldimethylammonium chloride) and poly(sodium 4- styrenesulfonate). Selected cations are Mg2+, Ca2+, Sr2+, Ba2+, Ni2+, Zn2+ and Cu2+ . The growth of films up to ten layers was monitored by ellipsometry, while morphology and surface roughness were determined by atomic force microscopy. The change in surface wettability during adsorption was monitored by tensiometry. Ion-specific effect was observed for alkaline earth metal cations, while in the case of transition metal cations it was not. The thicknesses, roughness and wettability of films prepared with transition metal cations are similar, while these properties differ for multilayers prepared with cations of alkaline earth metals.
