In this study, a commercial compressed-polyurethane (C-PU) mask was modified by applying a hydrophobic and anti-droplet coating using a silica sol, which was formed by the hydrolysis of tetraethoxysilane (TEOS) under alkaline conditions and hydrolyzed hexadecyltrimethoxysilane (HDTMS) to achieve hydrophobization. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 The methodology for fabricating a stable hydrophobic coating on a mask surface utilizing silica 202 sol as well as HDTMS is discussed in materials and methods section and summarized in 203 Scheme 1.	./cache/cord-347390-xz5a99cr.txt	./txt/cord-347390-xz5a99cr.txt
