<p>PURPOSE: A method for preparing a nanocrystal-polydimethylsiloxane composite is provided to prevent the composite from lumping together or oxidized by external factors. CONSTITUTION: Nanocrystal-polydimethylsiloxane bonded with polydimethylsiloxane derivative includes urea bonding on the surface of the nanocrystals. The polydimethylsiloxane derivative is represented by formula 1. In formula 1, R1 and R9 are independently C1-C20 aromatic or aliphatic amine groups; R2, R5, and R8 are independently C1-C20 aromatic or aliphatic groups; R3, R4, R6, and R7 are independently hydrogen, or C1-C20 aromatic or aliphatic groups; and n and m are integers between 2 and 10.</p> |
