Table 1. Water Contact Angles and BET Surface Area (SA_BET) Measurements for Chemically Treated Samples^a.

sample	water contact angle [deg]	SA_BET [m² g^–1]
nylon-12		–2.37 ± 2.06
TiO₂ “sol”	134 ± 5.31	6.22 ± 0.133
titanium(IV) butoxide	134 ± 5.08	4.13 ± 0.143
Titanium(IV) butoxide–TEOS mix	99.3 ± 16.9	5.93 ± 0.314
TEOS	70.0 ± 2.82	4.82 ± 0.212
(3-aminopropyl)triethoxysilane	124 ± 5.02	–0.142 ± 0.00

Note that the untreated nylon-12 sample was hydrophilic and absorbed the water droplet.
