PREPARATION AND CHARACTERIZATION OF THREE-COMPONENT INTERPOLYELECTROLYTE COMPLEXES OF CHITOSAN

Khudoyberdiyev Sh.Sh., Vokhidova N.R., Rashidova S.Sh.


Three-component interpolyelectrolyte complexes based on Bombyx mori chitosan were synthesized, and their compositions and hydrodynamic dimensions were characterized. It was established that, at pH 6.3, binary chitosan/collagen complexes interact with sodium carboxymethylcellulose in a mass ratio of 1:0.2:0.65. Additionally, ... Read More

CONCENTRATION DEPENDENT RHEOLOGICAL BEHAVIOR OF PAN COPOLYMER SOLUTIONS AND STRUCTURAL CHARACTERIZATION OF ELECTROSPUN FIBERS

Turayev J.I., Ashurov N.Sh., Abdurazokov M., Shakhabutdinov S.Sh., Atakhanov A.A.


This study establishes a direct quantitative link between rheological parameters and nanofiber structure. As the concentration increased, a significant transition from viscous to elastic-dominant behavior was observed, indicating the formation of a more interconnected polymer network. Electrospinning was subsequently ... Read More
