Claim:
A surface modifier comprising an organosilicone compound represented by General Formula (A): F—(CF 2 ) q —(OC 3 F 6 ) m —(OC 2 F 4 ) n —(OCF 2 ) o (CH 2 ) p XX″Si(X′) 3-a (R 1 ) a wherein q is an integer from 1 to 3; m, n, and o are independently integers from 0 to 200; p is 0, 1 or 2; X is oxygen (—O—), an amide group (—C(═O)—NH—), or an ester group (—C(═O)—O—); X″ is a bivalent organosilicone spacer group comprising —R 3 Si(R 2 ) 2 (OSi(R 2 ) 2 ) b O— or —R 3 Si(R 2 ) 2 (OSi(R 2 ) 2 ) b R 3 —, where R 2 is independently a C 1-22 hydrocarbon group, R 3 is independently a C 1-22 linear or branched optionally substituted alkylene group, and b is an integer from 1 to 100; R 1 is a C 1-22 linear or branched hydrocarbon group; a is an integer from 0 to 2; and X′ is a hydrolysable group selected from an alkoxy or alkoxy substituted alkoxy group, an acyloxy group, an alkenyloxy group, an iminoxy group, a substituted amino group, an amido group, a substituted aminoxy group, or halogen.
