چکیده
Abstract Thermoresponsive hydrogels based on ionic cellulose/chitosan are widely used various fields, such as smart windows and tissue engineering, while the effect of carbohydrate backbones thermal response mechanical properties has received less attention so far. Herein, poly(2(dimethylamino)ethyl methacrylate) (PDMAEMA)-grafted cellulose sulfate (P-CS) PDMAEMA-grafted chitosan (P-CHS) research models successfully synthesized through multi-step reactions. The P-CS P-CHS polymers further applied in crosslinked polyacrylamide networks, resulting hydrogels. Compared to hydrogels, could obviously block transmission visible light when temperature is changed from 25 42 °C. In contrast change easily soft weak state stiff strong according their behaviors. These results indicate that different should have caused distinct aggregation behaviors corresponding which accompanied by transmittance properties. Graphical abstract using prepared. Distinct backbone displayed effects thermoresponsive
