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 NH2 group, an NHR group (where R is alkyl group) and a COY group (where Y is a hydrophilic group); RF is 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 (CH2O)l—[Si(CH3)2O]k—(CH2O)l-α, (CF2)j-α or (CF2O)h-α where α is COY group (where Y is hydrophilic group), NCO group, NH2 group, 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. |
