Researchers in the UK have developed a thin, 30 μm, flexible, robust low-density polyethylene (LDPE) film loaded with 30 wt% P25 TiO2 and subsequently rendered highly active photocatalytically by exposing it to UVA (352 nm, 1.5 mW cm−2) for 144 h. The film was tested for anti-viral activity using two strains of influenza A virus, a highly stable picornavirus called EMCV and SARS-CoV-2, exposing it to either UVA radiation or with light from a cool white light fluorescent lamp. The film was effective at killing all the viruses—even in a room lit with just white fluorescent tubes. The film is degradable, low cost to produce, and can be readily scaled. It can be useful in medical setting and food industry…read more. Open Access TECHNICAL ARTICLE
