Table 2. Advancing Contact Angle of DI Water and Hexadecane on All Surfaces^a.

	DI water	hexadecane	surface energy (mJ/m2)
Ti	92	19	27.75
A	98	24	25.85
Ti1	40	0	57.56
A1	63	0	42.07
Ti2	18	0	69.36
A2	30	0	63.07
Ti3	76	0	34.70
A3	65	0	40.81

^aThe values were rounded off to zero decimal places. There is a significant difference in surface energy (p < 0.05) between all surfaces except A1 and A3 and Ti and Ti3.
