The Characterization of a New Antibacterial Polyurethane

Abstract

In this paper, Fe-OCAP/PU blends were prepared. The mechanical properties and thermal stability of the samples were studied by tensile tests and thermogravimetric analysis, respectively. Results showed that the mechanical properties and thermal stability of the samples were improved with the increase of Fe-OCAP content. The antibacterial property of Fe-OCAP and Fe-OCAP/PU films was investigated by agar diifusion method and shake flask method, respectively. Fe-OCAP and Fe-OCAP/PU films showed efficient antibacterial activity againstS.aureus.

Fabrication and Characterization of Antibacterial Polyurethane Acrylate-based Materials

“…Polyurethane (PU) is an important polymer, used in industry as adhesives, foams, coatings, rubbers and composites 15,19 . Moreover, shape memory and implant materials with their evident biocompatibility have been investigated and their structure and property correlations derived.…”

Preparation and characterization of Fe‐Tetranitro phthalocyanine/polyurethane blends

“…The percentage bacterial reduction toward S. aureus for Pc0.5 and Pc1 was 98.8% and 98.9%, while the percentage bacterial reduction toward E. coli for Pc0.5 and Pc1 was 87.4% and 90.9%. Compared with Fe‐OCAP/PU blends, where Fe‐OCAP/PU blends showed 96% bacterial reduction toward S. aureus when 5% Fe‐OCAP was added into PU, Fe‐TNPc/PU blends showed a higher efficiency toward bacterial inactivation. The modified samples had a high activity toward bacterial inactivation for both Gram‐positive bacteria and Gram‐negative bacteria and may have a potential industrial application in antibacterial fibers, coatings, etc.…”

“…In our previous reports, Fe‐octacarboxyl acid phthalocyanine (Fe‐OCAP)/polyurethane (PU) blends were prepared . Improved antibacterial property of the samples was obtained by the addition of Fe‐OCAP.…”
