TLDR
There was amide formation between chitosan and organic acids after treatment especially in chitOSan acetate and propionate films, and change in the degree of crystallinity from powder X-ray diffractogram and thermal characteristic from DSC thermogram were related to the water sorption and dissolution of films.About:

Chitosan-starch composite film: preparation and characterization.
TL;DR: In this article, a chitosan/starch composite film was used to evaluate the tensile strength (TS), elongation-at-break (E ), and water vapor transmission rate (WVTR) of the composite film.
Journal ArticleDOI
Characterization of quinoa protein–chitosan blend edible films
TL;DR: In this paper, a solution casting of blends of quinoa protein extract (PE) and chitosan (CH) was used to obtain quinoa proteins and CH, forming a new material with enhanced mechanical properties.

FTIR studies of chitosan acetate based polymer electrolytes
Zurina Osman,Abdul Kariem Arof +1 more
TL;DR: In this paper, when chitosan and ethylene carbonate (EC) are dissolved in acetic acid to form a film of plasticized chiton acetate, the infrared spectrum of the films do not show any significant shift indicating that EC does not interact with chitonsan.
Journal ArticleDOI
Preparation and properties evaluation of chitosan-coated cassava starch films
TL;DR: In this paper, chitosan-coated cassava starch films were prepared and X-ray patterns of the coated dry film showed that the reflection of B-type starch crystalline shifted to slightly higher degrees at about 17.2° (2θ).

Molecular and crystal structure of the anhydrous form of chitosan
TL;DR: In this article, the molecular and crystal structure of chitosan, a (1→4)-linked 2-amino-2-deoxy-β-D-glucan, has been determined by combined X-ray diffraction analysis and stereochemical model refinement.

Chitosan carboxylic acid salts in solution and in the solid state
S. Demarger-Andre,Alain Domard +1 more
TL;DR: In this paper, Fourier transform infra-red (FTir) spectroscopy and potentiometric techniques were used to characterize the nature of such interactions, in aqueous solutions and in films.
Journal ArticleDOI
Effect of Heating an Aqueous Suspension of Chitosan on the Crystallinity and Polymorphs.
TL;DR: In this paper, changes in the crystallinity and polymorph of chitosan, which may affect its functionality, by heating (up to 200°C) its water suspension were studied by X-ray diffraction measurements.
Journal ArticleDOI
Chitin derivatives. I. Kinetics of the heat-induced conversion of chitosan to chitin
TL;DR: The thermally-induced conversion of chitosonium acetate in film form into a water-insoluble chitin film was examined by thermal analysis (DMTA, TGA, DSC, and TMA) and by solid state 13C-NMR spectroscopy as mentioned in this paper.
