Blends containing chitosan and poly(sodium-4-styrene sulphonate). Compatibility behavior

Characterization of surface properties of Chitosan, Polytetrahydrofuron and their blends

“…The values of roughness parameters of the investigated samples are given in the table 2.According to the observation, the roughness of the blends were increased with increase in Chitosan concentration. Similar types of directions for changes were also observed in other Chitosan blends [7][8][9] Table1. Different Values of contact angles, dispersive (ysd) and surface free energy (ys )and its polar(ysp )components for Chitosan, PTHF and their blends.…”

Heparin-Mimetic Chitooligosaccharides-Based Monoliths Obtained from C/W Emulsions: Hemocompatibility and Toxin Removal Ability

“…The peaks at 3432 and 3197 cm –1 in PAM were attributed to O–H and N–H stretching vibrations, respectively . The absorption peak at 1674 cm –1 in P 30 A 1 N 1 C 0 was attributed to the stretching vibration of the amide carbonyl group of PAM, the absorption peaks at 1531 and 1412 cm –1 were the backbone vibration peaks of the benzene ring, and 1178 cm –1 was the symmetric and asymmetric stretching vibration of the −SO 3 – group. , The absorption peaks at 833 cm –1 were attributed to 1,4-disubstituted benzene for P 30 A 1 N 1 C 0.4 , and the symmetric and asymmetric stretching absorption peak for the −SO 3 – group was 1190 cm –1 , which was attributed to the formation of hydrogen bonds between the sulfonate group in P 30 A 1 N 1 and the −NH 2 or −OH of chitosan …”

Optimization and characterization of taro starch, nisin, and sodium alginate-based biodegradable films: antimicrobial effect in chicken meat

“…Bands were found at 1,595 cm −1 , indicating a vibration of asymmetric tension of the COO–, and at 1,411 cm −1 , a symmetric vibration of COO– ( Petrova et al, 2022 ). On the other hand, bands at 1,081 and 1,022 cm −1 were related to the asymmetric stretching and flexing of C–O ( Castro et al, 2011 ), a band at 947 cm −1 was related to a type of C–O bond ( Xu, 2006 ), and finally, bands at 887 and 815 cm −1 were related to a C–C bond.
