Abstract
A nanoparticle includes a chain oligomer section having a hydrophilic group and fluoroalkyl groups respectively at its opposite terminals, a three-dimensional silica network section, and an organic chain having fluorine or silicon, and is represented by the following formula (2): where R' is independent H or independent alkyl group; X is the hydrophilic group and is selected from the group consisting of an OH group, an NCO group, an NHgroup, an NHR group (where R is alkyl group) and a COY group (where Y is a hydrophilic group); Ris the fluoroalkyl group having a carbon number of 2 to 10 and a molecular weight of 119 to 1000; 3D-SN is the three-dimensional silica network section; B is selected from the group consisting of an O, O═C—O, NH—C═O and NR—C═O (where R is alkyl group); E is O, O═C—O, NH—C═O or NR—C═O (where R is alkyl group); L is (CHO)—[Si(CH)O]—(CHO)-α, (CF)j-α or (CFO)-α where α is COY group (where Y is hydrophilic group), NCO group, NHgroup, NHR group (R is alkyl group), R group (or alkyl group) or H; n is 1≦n≦10; m is 1≦m≦n; k is 1≦k≦500; l is 0≦1≦10; j is 0≦j≦20; and h is 1≦h≦20.
