Multifunctional magnesium oxychloride based composite with stable superhydrophobicity, self-luminescence and reusability
Graphical abstract Multifunctional magnesium oxychloride (MOC) based composite with rough surface, which contains hydrophobic materials mixed and luminescent powder, can emit green light and endure mechanical and chemical damages. The waste products can be ground to powders, applying to superhydrophobic coating and directional water transport. Display Omitted
Highlights Superhydrophobicity can withstand mechanical and chemical damage. Enhancement of water-resistance based on hydrophobic modification. Ability of Self-luminescence is suitable for sign in darkness. Recycle waste materials for SHP luminous coating and directional water transport.
Abstract Magnesium oxychloride (MOC) based materials have attracted much concern because of the superior mechanical properties and environmental friendliness, however, the widespread application is limited by the poor water-resistance and the tedious function. Thus it is worthwhile devoting much effort to overcome the defects. Here, taking sandpaper as template and with the modification of fluorinated HPDMS and luminescent powder, an effective method is proposed to produce MOC based composite with superhydrophobicity, self-luminescence and reusability. The samples can keep superhydrophobic (SHP) after enduring mechanical and chemical treatments, and even the crushed sample is still superhydrophobic. Meanwhile, SHP modification is helpful for overcoming the poor water-resistance, because the main phases are protected by the hydrophobic layer. After excitation, the composite materials can emit green light, which will gradually decay with time. The superhydrophobicity makes the material endure to be used for buildings with self-cleaning and deicing ability. Moreover, the powders ground from waste samples exhibit superhydrophobicity, implying the potential recyclability of this material, which can be applied to SHP luminous coating for house decoration and traffic signs in darkness, and directional water transport as well.
