The shape shown is exemplary and the present invention is not limited thereto. For example, in the water system, the poly ion composite 30 may form a stable particle structure by self-assembly. In addition, the shape of the poly ion composite 30 may vary depending on the mixing ratio of the cationic monomer 20 to the water soluble anion polymer 10.

The hydrophobic cationic monomer 20 may include any one or a combination of lecithin, cocobetaine, cetyltrimethylammonium bromide, cetyltrimethylammonium chloride, dimethyldiooctadecyl ammonium chloride. The hydrophobic cationic monomer 20 increases the hydrophobicity of the poly ion composite 30 to assist in the formation of the self assembly of the poly ion composite 30 in the aqueous solution.
