A coating composition containing an aqueous suspension based on a polycarboxylic acid, preferably phosphocitric acid, micro-and/or nano-sticks of zinc oxide, is described. Moreover, it is described a process for its preparation, comprising the preparation of an aqueous suspension by dispersing the zinc oxide micro-sticks and/or the zincoxide nano-sticks into an aqueous solution containing a polycarboxylic acid, preferably phosphocitric acid. The coating composition according to the present invention is particularly suited to coat porous materials and has high antimicrobial and antisaline activities. |
