An innovative experimental pathway for the synthesis of mesoporous silica particles as inhibitor containers for anticorrosive coatings

Description

ABSTRACT
Our novel experimental setup, which consists of a water re-circulator and high-speed disperser attached to a double-walled stainless-steel container, offers a fresh and efficient method for the regulated synthesis of mesoporous silica particles (MSPs). With the setup, we co-constructed inhibitor-bearing MSPs using the inhibitor benzotriazole (BTA) via a one-pot synthesis for use in anticorrosive coatings. A benefit of the experimental approach is the large amount of reactant solution that can be employed, while maintaining good control over the temperature of the solution and the conditions during stirring. This leads to higher yields and less laboratory time. The results obtained from the modified Stöber method show near-spherical nanometer-size (~ 310 nm) MSPs with high benzotriazole encapsulation capacity (46 wt.%). Moreover, the one-pot BTA encapsulated approach revealed spherical MSPs with mean diameter ~ 1.1 μm and BTA encapsulation of 23 wt.%, both showing smart anticorrosive potentials in waterborne epoxy coating for steel.
