Cw. Nam et al., Modification of polyacrylonitrile (PAN) fiber by blending with N-(2-hydroxy)propyl-3-trimethylammonium chitosan chloride, J APPL POLY, 74(9), 1999, pp. 2258-2265
N-(2-Hydroxy)propyl-3-trimethylammonium chitosan chloride (HTCC) was synthe
sized by the reaction of glycidyltrimethylammonium chloride (GTMAC) and chi
tosan. The reaction product was a water-soluble chitosan derivative, and sh
owed excellent antimicrobial activity. HTCC was blended with polyacrylonitr
ile (PAN) using an NaSCN aqueous solution as a common solvent. The blend so
lution was transparent and stable up to 6 months without phase separation.
The PAN/HTCC blend fibers were prepared via a wet spinning and drawing proc
ess. Thermal, electrical, and mechanical properties as well as antimicrobia
l activity were investigated. It was found that the antistatic property and
antimicrobial activity of the blend fibers could be achieved by adding onl
y a small amount of HTCC. (C) 1999 John Wiley & Sons, Inc.
