Microemulsion Encapsulated into Halloysite Nanotubes and their Applications for Cleaning of a Marble Surface
Halloysite nanotubes were used Blade Guards to incorporate anionic surfactant micelles and an organic solvent to generate a cleaning system to be applied in Cultural Heritage restoration.The targeted adsorption is driven by electrostatic interactions based on the nanotubes peculiar charge separation.Namely anionic species are driven to the positive
