Raw Data
Fig 1. Contact angles was measured on the bare siuz suosurate anu nuviDS-treated SiO2 substrate with using DI water -41.4 and 66.6(left and right, respectively), while using Diodomethane -32.0 and 41.1
2. Discussion
2(1+cos)=21d2d2+21p2p2 Owens-Wendt-geometric mean
2=2d+2p,3=3d+3p
2d=22.0mJm2 DI water Surface energy - dispersion term
2p=50.2mJm2DI water Surface energy - polar term
3d=48.5mJm2 DilO Surface energy - dispersion term
3p=2.3mJm2 DIIO Surface energy - polar term
Under the Condition of Phase; 1= Solid 2= Water 3= Diiodomethane
2(1+cos2)=21d2d2+21p2p2
3(1+cos3)=21d3d2+21p3p2
With the value of ,2d,2d,3d,3d, we can know s=1d+1d
2-1) Calculate the surface energy of each substrate (SiO2, HMDS) with Owens-Wendt geometric mean.
(a) Surface Energy polar term of Bare SiO2 substrate (1p)
(b) Surface Energy dispersion term Bare SiO2 substrate (1d)
(c) Surface Energy of Bare SiO2 substrate (1)
(d) Surface Energy polar term of HMDS-treated SiO2 substrate (1p)
(e) Surface Energy dispersion term HMDS-treated SiO2 substrate (1d)
(f) Surface Energy of HMDS-treated SiO2 substrate (1)
