Abstract

Damage to the highly pathogenic avian influenza virus(H5N1) continues to increase, but there is a lack of antiviral research. In this study, we analyze antiviral properties on H5N1 by coating Cu/TiO2 photocatalyst on polyethylene films. The specimen was manufactured a photocatalyst master batch and coated both sides of the 3-layer polyethylene fabric at 280℃ from the extrusion coating machine. The results showed a 99.9% decrease in the Staphylococcus aureus and Escherichia coli. In particular, H5N1 type highly pathogenic avian influenza viruses, which is capable of human infection, has been found to decrease 99.9% within five minutes of contact with Cu/TiO2 films. Antibacterial effects of films coated with photocatalyst are known, but this study also confirmed the antiviral effects.

고병원성 조류독감 바이러스(H5N1)에 대한 피해가 지속적으로 증가하고 있으나, 이에 대한 항바이러스성 연구는 부족한 상황이다. 본 연구에서는 폴리에틸렌 필름에 Cu/TiO2 광촉매를 코팅하여 H5N1에 대한 항바이러스 특성을 분석하였다. 시료는 광촉매 마스터배치를 제조하여 압출코팅기에서 280℃로 3중 레이어 폴리에틸렌 원단의 양면을 코팅하였다. 그 결과 황색포도상구균과 대장균의 균수가 99.9% 감소되는 것으로 나타났다. 특히 인체감염이 가능한 H5N1형 고병원성 조류인플루엔자는 Cu/TiO2계 필름에 접촉 5분 이내 99.9% 감소하는 것으로 확인되었다. 광촉매를 코팅한 필름의 항균성에 대해서는 알려져 있지만 본 연구를 통해 항바이러스성에 대해서도 확인이 가능하였다.
