STUDY OF CHITOSAN PROTECTIVE PROPETIES IN COLLOIDAL SOLUTIONS OF CADMIUM SELENIDE QUANTUM DOTS
Abstract
In this paper, by a low-temperature colloidal aqueous method, without the use of toxic media, the quantum dots of cadmium selenide in the shell of chitosan were synthesized. Chitosan was used as a matrix for the growth of colloidal semiconductor particles, and it also stabilized the obtained particles.
The purpose of this work was studying the protective properties of chitosan in colloidal solutions of cadmium selenide quantum dots. The objective of the study was to analyze the protective effect of chitosan in colloidal systems by analyzing the optical and rheological properties of the obtained solutions.
The dependence of the light transmission of colloidal solutions of cadmium selenide quantum dots in the shell of chitosan on the concentration of polysaccharide was investigated.
It has been established that the light transmission of colloidal solutions decreases with time, the lower the content of chitosan in solution, which indicates that the protective action of colloidal solutions of quantum dots of cadmium selenide increases with increasing concentration of the polysaccharide.
A study was made of the kinematic viscosity of the obtained solutions with different concentrations of chitosan in time. It was established that when the quantum dots are formed in the chitosan matrix, the viscosity of the colloidal system decreases. The protective effect of chitosan increases with increasing concentration in the solution.Downloads
