Ethanol soluble complexes of cationic polyelectrolyte-anionic surfactant were obtained. The properties of complexes in solution were studied by viscometry and dynamic laser scattering. Structure, morphology and surface properties of complexes in condensed... see more

Electrostatic interactions play important roles in the assembly, the structureand the functions of many biological as well as soft matter systems. In the presence of a macro-ion in aqueous solution, oppositely charged molecules mobilize around it to ... see more

Phase states of monolayers of organosoluble stoichiometric polycomplex based on cationic polyelectrolyte and anionic surfactant has been studied. Formation of mixed monolayers consisting of polyelectrolyte-surfactant complex (PSC) and dye molecules at wat... see more

Preparation of PEC chitosan-alginate films incorporated by eugenol has been investigated. Incorporation of eugenol in chitosan-alginate films was conducted by using the different concentration of eugenol including 0.25% 0.5%, and 1% (% w/v). The effect of... see more

This paper is dedicated to 70th anniversary of the prominent Kazakh chemist – professor Sarkyt Elekenovich Kudaibergenov. The information of biographical nature, showing the development of S.E. Kudaibergenov as a scientist, as well as his main research co... see more

A study of eugenol release and its kinetics model from chitosan-alginate polyelectrolyte complex (PEC) films has been conducted. Some factors that affected the eugenol release were also studied, including the composition of chitosan-alginate PEC and the c... see more

a wood residue – sawdust of the mechanical processing of aspen (Populus tremula) wood – was used to obtain a short fibre filler in the form of the modified microparticles < 250 µm for polymeric composite materials. To reduce energy input for ... see more

Chitosan is known as an antibacterial agent. The effective surface area ratio of chitosan can be increased by modification into nanoparticles. Nano-chitosan can be prepared with several simple methods, i.e. precipitation, ionic gelation, or the polyelectr... see more

The physico-chemical and complexing properties of the sorbent based on chloromethylated styrene and divinylbenzene copolymer with nicotinamide groups and copolymers based on metacryloilaminobenzene acids with 2-methyl-5-vinylpyridineisomers are studied. B... see more
