Superhydrophobic sponges and sponge-like materials have attracted great attention recently as potential sorbent for oil spill cleanup due to their excellent sorption capacity high selectivity. A major challenge broad use is the fabrication of superhydrophobic with superior recyclability, good mechanical strength, low cost, manufacture scalability. In this study, we demonstrate a facile, cost-effective, scalable method fabricate robust, through silanization commercial melamine via...
This report describes methods to produce large-area films of graphene oxide from aqueous suspensions using electrophoretic deposition. By selecting the appropriate suspension pH and deposition voltage, negatively charged sheets can be produced with either a smooth "rug" microstructure on anode or porous "brick" cathode. Cathodic occurs in low application relatively high which facilitates gradual change colloids' charge negative positive as they adsorb protons released by electrolysis water....

Alternating layer, carbon nanotubes-nanocrystal composite films, comprising multi-walled nanotubes (MWCNTs) and iron oxide (Fe(3)O(4)) nanocrystals, have been fabricated via electrophoretic deposition (EPD) on stainless steel gold substrates. Low field-high current high field-low EPD schemes were integrated to produce the films. The low approach produced porous mats from an aqueous suspension of MWCNTs, while tightly packed nanocrystal films a dispersion nanocrystals in hexane. Large...
