Patent ID: 7943802

Claim:
A nanoparticle composite comprising: a host molecule including a chain oligomer section having a hydrophilic group and fluoroalkyl groups respectively at opposite terminals thereof and a three-dimensional silica network section, and the host molecule having a structure represented by the following formula (1): where X is the hydrophilic group and is selected from the group consisting of an OH group, an NCO group, an NH 2 group, an NHR group (where R is alkyl group) and an OCY group (where Y is a hydrophilic group); R F 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 independent O, independent O═C—O, independent NH—C═O or independent NR—C═O (where R is alkyl group); n is 1≦n≦10; and m is 1≦m≦n; and a guest molecule which is trapped by being confined in the three-dimensional structure of the host molecule.
