Abstract null null Smart coatings with inhibitor loaded nanocontainers exhibit significant efficiency and durability in prolonging metal life-time and reducing catastrophic failure. However, scaling and further practical intelligent anticorrosion applications of such coatings are still greatly limited by time-consuming installation of various nanovalves. Herein, hybrid hollow mesoporous organosilica was obtained by facile selective etching and served as valve-free nanocontainer to prepare smart ...

Abstract Most of existing nanocontainers suffer from tedious, complicated and unsustainable assembly process which restricts their application in corrosion protection as smart inhibitor carriers. In this study, we adopted the framework-hybridization approach to prepare a smart anticorrosion system (MBT@Ph-HPMO), with MBT inhibitor as cargo and phenylene-bridged hollow periodic mesoporous organosilica (Ph-HPMO) as nanocontainer. Results reveal that the π-π stacking between MBT and framework of Ph...

Self-assembly of asymmetric block copolymers (BCPs) around active pore edges has emerged as an important strategy to produce smart membranes with tunable pathways for solute transport. However, thus far, it is still challenging to manipulate pore shape and functionality for directional transformation under external stimuli. Here, a versatile strategy by mesoscale simulations to design stimuli-responsive pores with various edge decorations in hybrid membranes is reported. Dopant BCPs are used as ...

Abstract The redox-responsive hollow mesoporous silica sphere (HMSS) as smart nanocontainer demonstrates great potential for active agent storage and controlled release. In the present work, HMSS was firstly prepared by surfactant assisted selective etching method. Then, target corrosion inhibitors, 2-mercaptobenzothiazole (MBT) molecules, were loaded and encapsulated with redox-responsive supramolecular nanovalves, ZnO quantum dots. Results reveal that obtained HMSS exhibits a hierarchical meso...

Abstract Density functional theory was used to investigate the adsorption of imidazole (IMD), benzotriazole (BTAH) and 2-mercaptobenzoxazole (MBO) on the grain boundary (GB) of Cu (100) surface. Results show that molecules prefer to adsorb on the grain boundary with the larger distortion degree and more adsorption sites. The main interaction of molecules and grain boundary is chemisorption through C, N, S Cu bonds in both perpendicular and parallel modes. Hydrogen bonds and the lateral dipole-di...

Multigeometry nanoparticles with high complexity in composition and structure have attracted significant attention for enhanced functionality. We assess a simple but versatile strategy to construct hybrid nanoparticles with subdivided geometries through the cooperative assembly of diblock copolymer blends with asymmetric architectures. We report the formation of multicompartmental, vesicular, cylindrical, and spherical structures from pure AB systems. Then, we explore the assemblies of binary AB...

Abstract We present a simple approach for the fabrication of a full-thickness super-hydrophobic composite coating consisted of modified TiO 2 nanoparticles and polysiloxane resin. Scanning electron microscope (SEM), fourier transform infrared spectrometer (FTIR), contact angle meter and a simple self-made device were employed to characterize the surface morphologies, chemical compositions, contact angle and sliding angle of the modified TiO 2 nanoparticles and composite coating, respectively.
