Surface acidity of solids (ZSM-5 zeolites, Y zeolite, mordenite and Ca-bentonite) were investigated with Fourier transform infrared spectroscopy (FTIR) and Hammett acidity functions; the n-butylamine titration method. In the amine titration method, acid strength of solids were found. The total acid amount of Y zeolite has the highest value among all others. The IR spectrums of all samples were recorded using diffuse reflectance infrared Fourier transform (DRIFT) technique. Pyridine adsorption and desorption processes have given some clues about the surface acidity of solids.
The surface characterization of 2-(dimethylamino)ethylmethacrylate (DMA) and 2-(N-morpholino)ethylmethacrylate (MEMA) homopolymers and DMA-MEMA diblock copolymer was studied using inverse-gas chromatography (IGC).The analyzed surface properties of (co)polymers were the dispersive component of the surface energy (γ
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
