Surface contact angles of different filters, including (a) filters with 0.3, 0.9, and 1.2 mg MWCNT loadings; (b) filters with 1.2 mg MWCNT loading and 0.2, 0.3, or 0.5 mg nisin loading. Different letters above the bars indicate significant differences (P < 0.05). Different letters on the columns indicate a significant difference; the same letters on the columns indicate no significant difference
