NOVELTY - A coating agent comprises 0.01-1 wt.% graphene solution, 0.1-5 wt.% titanium dioxide, 0.01-0.9 wt.% platinum, 1-30 wt.% silica, 30-50 wt.% carnauba wax or 5-30 wt.% ladder-type silsesquioxane polymer resin (I), 1-30 wt.% ethanol, and 1-10 wt.% or 1-20 wt.% water. The graphene solution is obtained by mixing 10 g potassium persulfate, 10 g phosphorus pentoxide and 50 ml sulfuric acid, heating to 90 degrees C in hot water bath, cooling to 80 degrees C, adding 12 g graphite, reacting for 4-5 hours, diluting the mixture with 2 L distilled water, stirring for 12 hours, filtering the diluted solution using 0.2 mu m-nylon filter, pretreating the graphite particles with 460 mL sulfuric acid, adding 60 g potassium permanganate, stirring at 35 degrees C for 2 hours, adding 20-30 mL distilled water, maintaining at 40-50 degrees C, adding hydrochloric acid and distilled water in ratio of 1:2, stirring, adding 2.8 L distilled water, diluting, stirring for 3 hours, adding hydrogen peroxide, and stirring at pH of 5-7. USE - Agent is used for coating glass (claimed). ADVANTAGE - The coating agent has excellent removal effect with respect to volatile organic compound from room, durability, antifouling property, transparency, adhesiveness with respect to house dust which is a cause of pollen allergy, atopic dermatitis and asthma.
