Antimicrobial fibers based on chitosan and polyvinyl-alcohol
A series of antimicrobial fibers with different weight ratio of chitosan (CS) and polyvinyl alcohol (PVA) were fabricated via a primarily industrialized trail of wet-spinning method, and the morphology and structure of the resulting fibers were studied with the aid of scanning electron micrography (SEM), infrared spectroscopy (FTIR), and X-ray diffraction (XRD). The CP60 blend fiber (60 % chitosan...

1. Structural characterization and antimicrobial activity of chitosan/betaine derivative complex
关键字：Chitosan; Betaine derivative; Complex; Antimicrobial activity
Complex
of chitosan acetate (CSAC) with C12–C18 alkyl amido prophyl dimethylamine
betaine (AAPDB) was prepared and characterized by Fourier transform-infrared
(FT-IR), thermal analysis (TG, DTG and DSC), X-ray diffractogram. Results
showed that complex formed mainly by the electrostatic interaction between NH3t
of CSAC and COO2 of AAPDB. Minimum inhibitory concentrations (MICs) were
evaluated a...

Preparation and characterization of intercalated Ag/PVP-modified clay hybrids with good antimicrobial activity
关键字：Ag; clay; PVP; hybrid; antimicrobial activity
Intercalated Ag/PVP-modified clay hybrids have been prepared by in-situ reduction reaction using ascorbic acid as reductant in the presence of polyvinylpyrrolidone (PVP) which was used to increase the interlamellar space of Na+-montmorillonite&n...

Synthesis and antimicrobial activity of quaternized O-carboxymethyl chitosan assisted with ultrasonic irradiation
关键字：o-carboxymethyl chitosan; quaternization; ultrasonic irradiation; antimicrobial activity
O-carboxymethyl chitosan (OCMC) was synthesized by ultrasonic irradiation with chitosan and chloroaceticacid in NaOH-ethanol. The degree of substitution (DS) of carboxymethyl and amino retained amount (NH2%) were studied under the orthogonal exp...
