| Abstract: | Water‐resistant polymeric biocide poly(hexamethylene guanidine) dodecylbenzenesulfonate (PHMG‐DBS) was synthesized by anion metathesis between poly(hexamethylene guanidine) hydrochloride and sodium dodecylbenzenesulfonate and subsequently characterized using elemental analysis, Raman spectroscopy and thermogravimetric analysis. It is found that PHMG‐DBS is thermally stable to at least 350 °C, which makes it suitable for melt blending with polyamide (PA) resins. An antifungal PA‐12 composition was prepared by compression moulding of PA‐12 and PHMG‐DBS powder mixture at 240 °C. The characteristics of the prepared films were investigated: surface roughness and hydrophobicity using atomic force microscopy and contact angle measurements, respectively. No significant change in the material characteristics is observed compared to pure PA‐12 films. PA‐12 films containing 2 wt% of the PHMG‐DBS biocide are found to be highly resistant against Trychophyton mentagrophytes fungus. Copyright © 2012 Society of Chemical Industry |
