Modification of polyacrylonitrile (PAN) fiber by blending with N-(2-hydroxy)propyl-3-trimethyl- ammonium chitosan chloride

Abstract

propyl-3-trimethylammonium chitosan chloride (HTCC) was synthesized by the reaction of glycidyltrimethylammonium chloride (GTMAC) and chitosan. The reaction product was a water-soluble chitosan derivative, and showed excellent antimicrobial activity. HTCC was blended with polyacrylonitrile (PAN) using an NaSCN aqueous solution as a common solvent. The blend solution was transparent and stable up to 6 months without phase separation. The PAN/HTCC blend fibers were prepared via a wet spinning and drawing process. Thermal, electrical, and mechanical properties as well as antimicrobial activity were investigated. It was found that the antistatic property and antimicrobial activity of the blend fibers could be achieved by adding only a small amount of HTCC.

Copolymers of acrylonitrile with quaternizable thiazole and triazole side-chain methacrylates as potent antimicrobial and hemocompatible systems

“…Due to its importance in textile, water treatment or medicinal industries, many strategies are found to develop antimicrobial PAN materials in the latest years [9,[16][17][18][19][20][21][22][23][24]. For instance, recent research has focused on antimicrobial PAN nanofibers by adding silver nanoparticles [22,25,26], blends with other bioactive polymers [20,21,27], composites [19,23,28,29], chemical modification [30] or even adding antibiotics [18,22,25,31]. However, there exist only a few reported examples of antimicrobial PAN copolymers [32][33][34].…”

Preparation, Properties and Applications of Chitosan-Based Biocomposites/Blend Materials: A Review

“…It is expected that the antistatic properties and antimicrobial activity of hydrophobic PAN can be improved by introducing Cs as a co-polymer blend [259]. The Cs/PAN to blend composites was prepared by wet spinning and drawing process [260], and solution casting [261]. To increase the hydrophilicity of Cs/PAN blends, modified Cs; 2-hydroxypropyltrimethyl ammonium chloride chitosan (HACC) was used instead of native Cs [259,260,262,263].…”

The incorporation of PAN with native or/and modified Cs improved several performances of Cs filtration membranes, such as the reduction in swelling properties [261] while increasing the rejection of solute salt from waste water [263].…”

Electrospun PS/PAN fibers with improved mechanical property for removal of oil from water

“…Additionally, PS fibers had a poor mechanical behavior and could be easily destroyed in oil after oil sorption. Polyacrylonitrile (PAN) fibers Nam et al (1999) have been widely used in industry because of good conductivity, solvent resistance and high strength. However, PAN is hydrophilic and as a result is seldom used in oil sorption.…”
