Structure and Property of Cationic Hydroxyethyl Cellulose

Ductile nanocellulose-based films with high stretchability and tear resistance

“…CHEC retained these characteristic peaks, however a prominent, sharp peak emerged at 1447 cm À1 . This was attributed to the stretching vibration of CAN on the quaternary ammonium ion [21]. The peak corresponding to adsorbed water at 1645 cm À1 has almost completely diminished, appearing as a faint shoulder of the main peak at 1447 cm À1 , while the AOH peak at 3378 cm À1 experienced a similar reduction in intensity.…”

Preparation and characterization of hybrid cationic hydroxyethyl cellulose/sodium alginate polyelectrolyte antimicrobial films

“…In addition to the characteristic band of hydroxyethyl cellulose, the band of C─N stretching vibration at 1475 cm −1 is seen. But, the band of epoxy ether vibration at 1264 cm −1 in the FT‐IR spectrum of GTAC is not observed . These results demonstrate that the desired reaction between hydroxyethyl cellulose and GTAC is achieved and cationic hydroxyethyl cellulose is successfully synthesized.…”

Thermal Comparison of Montmorillonite / HEC and Sepiolite / HEC nanocomposites

“…HEC can be characterized by a low Tg, a long biphasic region and a broad mesophase to isotropic phase transition peak because of the size distribution of partially crystalline phase in amorphous phase (Bheda, Fellers, & White, 1980a, 1980bV. E. Gul, Khanchich, & Savchenko, 1996;Wang & Ye, 2010). In this study, HEC was not used in very concentrated form for film casting, so glass transition temperature can not be determined precisely for pure polymer.…”

“…The main peaks of HEC; the strong absorption peak at 3435 cm -1 shows of the presence of hydroxyl groups (-OH), besides of the absorption peaks at 2971 cm -1 and 2873 cm -1 are saturated alkyl (-CH3-, -CH2-), and the absorption peak at 900-1200 cm -1 are ether linkage peaks (C-O-C) (Wang & Ye, 2010) .…”
