Abstract

Provided is an electronic microparticle, including a first copolymer copolymerized from a first monomer and a second monomer or a second copolymer copolymerized from the first monomer, the second monomer and a third monomer. The first monomer includes an alkenyl group and excludes a sulfonic group, a carboxylic group, a hydroxyl group and an amino group. The second monomer includes an alkenyl group and further includes a sulfonic group or a carboxylic group. The third monomer includes an alkenyl group and further includes a hydroxyl group or an amino group. Either the first monomer or the second monomer has a ratio of the repeating units of the first monomer to the repeating units of the second monomer between about 200:1 and 20:1. In addition, an addition agent and a filtering membrane which include the electronic microparticle illustrated above are provided.
