| 1. A siloxane dispersant having a structure including a head part having affinity for nanoparticles and a tail part having
affinity for a polydimethylsiloxane resin,
wherein the siloxane dispersant contains the head part selected from the group consisting of:
 wherein each R is independently hydrogen or C1-C4 alkyl;
or a group represented by
 the tail part selected from the group consisting of:
 wherein n is an integer of 2 to 30, and x and y are independently an integer of 2 to 20; or
wherein the siloxane dispersant contains the head part selected from the group consisting of the formulas
 wherein each R is defined above, and the tail part is of the formula
 wherein x, and y are each defined above; or
wherein the siloxane dispersant contains the head part of the formula
 wherein each R is as defined above, and the tail part is
