Microwave Assisted Preparation of Antimicrobial Chitosan with Guanidine Oligomers and Its Application in Hygiene Paper Products
Guanidinylated chitosan (GCS) was prepared by grafting guanidine oligomers onto chitosan under microwave irradiation. The structure of GCS characterized by FT-IR and 1H NMR verified the covalent bonding between the guanidine oligomers and chitosan; the effects of molar ratio, reaction temperature, and time were investigated and the degree of substitution of GCS reached a maximum of 25.5% under ...
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 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 کاملMicrowave-assisted preparation and antimicrobial activity of O-alkylamino benzofurancarboxylates
ABSTRACT A series of derivatives of 2 and 3-benzofurancarboxylates were synthesized under microwave-assisted conditions. Their in-vitro antimicrobial properties were assessed. Inhibition by the compounds of the growth of antibiotic-susceptible standards and clinically isolated strains of Gram-positive and Gram-negative bacteria, yeasts, and a human fungal pathogen was moderate to significant. M...
