Fig. 5: Super antifouling performance of GAH in polluted raw sewage.
From: Multifunctional solar water harvester with high transport selectivity and fouling rejection capacity
a, Images of oil contact angle in water formed by fish scale (left) and GAH (right). Inset is the image of soybean oil on GAH. b, Mechanism of GAH’s anti-oil-fouling capacity by forming a stable solid/water/oil system on the patterned surface. c, Contact angle of methylbenzene, n-hexane, benzene, petroleum ether and hexamethylene on GAH surface under water. d, Mechanism of antibiosis of GAH based on rGO sheets on its patterned surface. Chemical sterilization of oxygen-containing functional groups and physical sterilization of nano-defects and edges contributes to antibiosis capacity. e, Regrowth test result of diluted raw lake water, control group and GAH-treated group. Images on the right refer to the culture dishes of control group and GAH-treated group.
