Facile approach to the green synthesis of novel ternary composites with excellent superhydrophobic and thermal stability property: An expanding horizon

In present study, a novel and facile strategy of electrophoretic deposition (EPD) with following perfluorodecyltriethoxysilane (FAS-17) modification is successfully introduced to fabricate superhydrophobic ternary composites-AlxNiy(Bi2O3)(z) with excellent superhydrophobic and thermal stability property. The chemical composition, morphology and heat-release performance of the products were analyzed by XRD, FESEM, FT-IR, EDX, DSC and a high-speed camera, respectively. The stable suspension consisted of isopropyl alcohol and additive-polyethyleneimine. The deposition mechanism of ternary composite coating was firstly given, and EPD kinetics were investigated in detail. Moreover, the water contact angle and roll-off angle of superhydrophobic AlxNiy(Bi2O3)(z) with as well as significant water bouncing properties can reach to 169 +/- 2 degrees and ca. 1 degrees, respectively. In addition, superhydrophobicity and internal chemical energy (ca. 2 MJ kg(-1)) of products all keep almost stable after 300 days, exhibiting a high value of practical application. Thus, this study provides a promising and low cost method for the synthesis of various superhydrophobic composites with long-term storage stability in different humidity environments and zones, even underwater.
