Chinese researchers synthesized 1H-benzotriazole (BTA) loaded hollow silica nanocapsules with magnesium hydroxide precipitate in the shells (HSNs-M/BTA) through inverse microemulsion (W/O) polymerization.

It was shown that by the changing of pH in the corrosion solution, the release of BTA can be triggered. Water contact angle results showed that the anticorrosive SiOx/ZrOx coatings embedded with hydrophobically modified HSNs-M have a contact angle value of 140°.

The corrosion performance of this developed system was enhanced and this method  is promising as an intelligent element in protective coatings in the future.
