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 (1):where R′ is independent H or independent alkyl group; X is the hydrophilic group and is independent OH group, independent NCO group, independent NH2group or the like; RFis 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 independent O, independent O═C—O or the like; E is O, O═C—O, NH—C═O or the like; G is [(CH2O)1—[Si(CH3)2O]k—(CH2O)1] or the like.
