Synthesis and characterization of new arylamine chitosan derivatives
(WILEY-BLACKWELL, 2004)
The synthesis of new chitosan derivatives and their complete characterization by elemental analysis, Fourier transform infrared, thermogravimetric analysis, and cross-polarity/magic-angle-spinning (13)C NMR is described. ...
Ftir and tga studies of chitosan composite films
(SOC CHILENA QUIMICA, 2004)
The synthesis of chitosan and resulting chitosan composite films was carried out using glycerol, tween, and beeswax as additives to prepare the composites films, after which a complete study by FTIR was carried out for all ...
Retention capacity of chitosan for copper and mercury ions
(SOC CHILENA QUIMICA, 2003)
Chitosan, was obtained from red lobster shells (Pleuroncodes monodon). The <(M)over bar v> of chitosan prepared was 54.000 g/mol with a deacetylation degree of 80%. The retention capacity of chitosan for copper and mercury ...
Hydrogels Based On Alkylated Chitosan And Polyelectrolyte Copolymers
(2018)
Hydrogels formed by alkylated chitosan with N-(3-chloro-2-hydroxypropyl) trimethylammonium chloride and synthetic copolymers forming polyelectrolyte complexes are presented. The copolymer polyelectrolytes were synthesized ...
Synthesis and unisual swelling behavior of combined cationic/non-ionic hydrogels based on chitosan
(2003)
Hydrogel-forming copolymers based on chitosan grafted with different amounts of polyacrylamide were synthesized and its swelling capacity determined in distilled water, sodium chloride solutions, as well as in buffer ...
Porous silica derived from chitosan-containing hybrid composites
(2003)
In this paper, we report the preparation by the sol-gel technique of organic–inorganic hybrid composites containing the biopolymer chitosan incorporated in a siloxane-based inorganic network. The hybrid xerogels were ...
Study of the effect of reaction variables on grafting of polyacrylamide onto chitosan
(2002)
The biopolymer chitosan was chemically modified by grafting polyacrylamide in a homogeneous aqueous phase by using potassium persulfate as redox initiator system and in the presence of N,N-methylene-bis-acrylamide as a ...
