Quaternary ammonium salt of chitosan: preparation and antimicrobial property for paper
A series of 2-hydroxypropyltrimethyl ammonium chloride chitosan (HACC) was prepared by the reaction of chitosan with glycidyl trimethyl ammonium chloride. Structure of HACC was characterized by FT IR and 1H NMR spectroscopies, and it was proved that substitution reaction mainly occurs on the N element. Antimicrobial activities of HACC was examined against S. aureus, E. coli, and A. niger. Resul...
متن کاملPreparation of Antimicrobial Paper Sheets Using Chitosan
The purpose of this study was the antimicrobial functionalization of paper pulp with natural biopolymer chitosan. Laboratory paper sheets were prepared for this purpose from paper pulp with incorporated chitosan. The prepared paper sheets were analysed regarding amino group content, mechanical properties and hydrophilicity. All of these parameters are important for hygienic applications of pape...
متن کاملHDPE/Chitosan Blends Modified with Organobentonite Synthesized with Quaternary Ammonium Salt Impregnated Chitosan
In this study, blends based on a high density polyethylene (HDPE) and chitosan (CS) were successfully prepared by melt processing, in a laboratory internal mixer. The CS biopolymer content effect (up to maximum of 40%), and, the addition of bentonite clay modified with quaternary ammonium salt (CTAB) impregnated chitosan as a compatibilizing agent, on the properties of the blends was analyzed b...
متن کاملPreparation of Chitosan-Copper Nanoparticles Coated Kraft Paper, Characterization and its Antimicrobial Activity
In this paper, Chitosan-copper nanoparticles were successfully coated onto the Kraft paperusing a dip coating process. First, chitosan-copper nanoparticles solution was prepared byreduction method and the use of ultrasonic radiation. It was employed copper sulphate pentahydrateas precursor salt, NaOH as a reducing agent and Chitosan as capping agent to prepareChitosan-copper nanoparticles solut...
متن کاملPreparation, characterization and antimicrobial property of ag+- nano Chitosan/ZSM-5: novel Hybrid Biocomposites
Objective(s): Binary hybrids of chitosan-zeolite have many interesting applications in separation and bacteriostatic activity. Materials and Methods: Template free ZSM-5 zeolite was synthesized by hydrothermal method, physical hydrogels of nano chitosan in the colloidal domain were obtained in the absence of toxic organic solvent and then nano chitosan/ZSM-5 hybrid composites with nano chitosan...
