Material Porosity

The surfaces of building materials are constantly exposed to the actions of environmental factors, pollutants of inorganic and organic origin as well as to microorganisms, which significantly contribute to corrosion phenomena.The application of coatings decreases the negative action of the pollutants minimizing their direct contact with the substrate. Different types of coatings with additional functions have been developed. A specific problem of these applications is the lack of compatibility of the photocatalysts with the surface of the building materials and the detachment of potentially toxic TiO2nanoparticles. In the present study, this problem was solved by the proper immobilization of TiO2nanoparticles onto the photocatalyst support, layered double hydroxides (LDHs). The newly formed coating possesses acceptable porosity for a porous building material (porosity within the range of 30-46 %) and satisfied photocatalytic activity, as well as mineralogical compatibility with the substrates (mortars, renders, bricks). Additionally, a positive effect considering the self-cleaning phenomenon was attained.

Antibacterial Factor

Due to their biocompatibility, nanomaterials type layered double hydroxides (LDHs) development has attracted many researchers attention especially in medical area using them as drug delivery vectors. Their efficiency is due to the drug controlled release from the interlayer space of LDHs matrices. The controlled drug delivery characteristic is due to the reduction of drug concentration variations and maintains the desired level of drug concentration for long time. Furthermore, this action limits adverse effects and reduces the therapy duration, enhancing bactericidal activity and leading to an effective treatment. This work highlights the synthesis and characterization of hybrid structures type LDHs- tobramycin having application as antibacterial factor against Pseudomonas aeruginosa. The obtained self-assembled structures were morphologically characterized in order to point out the drug-interlayered products. Results indicate superior properties of MgAlLDHs and ZnAlLDHs behaving as host for a wide variety of molecules generally and, in our case, for tobramycin as guest.
