Abstract:
1. An electronic microparticle, comprising: a first copolymer polymerized from a first monomer and a second monomer or a second copolymer polymerized from the first monomer, the second monomer and a third monomer, wherein the first monomer comprises an alkenyl group and excludes a carboxyl group, a sulfonic group, a hydroxyl group and an amino group, the second monomer comprises an alkenyl group and further comprises a carboxyl group or a sulfonic group, and the third monomer comprises an alkenyl group and further comprises a hydroxyl group or an amino group, wherein either the first copolymer or the second copolymer has a ratio of the repeat units of the first monomer to the repeating units of the second monomer between 200:1 and 20:1.
