Durable superhydrophobic and superoleophilic filter paper for oil–water separation prepared by a colloidal deposition method

Facile preparation and characterization of modified magnetic silica nanocomposite particles for oil absorption

“…In recent years, nano composite materials used for oil removal can be broadly divided into two categories: nano hierarchical structure for the purpose of oil-water separation, such as stainless steel mesh [16], nano film [17,18], foam [19][20], etc. [21][22][23][24][25][26][27], and oil M a n u s c r i p t absorption materials e.g., nano hole fiber [28,29], polymer nanocomposite [30][31][32][33] and porous graphene [34][35][36][37][38]. These oil absorbents have promising performances but still possess certain limitations, for instance poor recyclability, environmental incompatibility, harsh reaction conditions, expensive cost and so on.…”

Functionalized Cellulose Networks for Efficient Oil Removal from Oil–Water Emulsions

“…Numerous efforts have been made in order to turn these materials into water-resistant multifunctional systems, thus expanding their applicability in diverse technological fields [17][18][19][20]. To this end, studies have been conducted on the surface modification of cellulosic FP, which is commonly used for particle separation/filtration processes [9], in order to be utilized as an oil-water separator [5][6][7][8][9][10][11]. However, the majority of the proposed treatments demand complex preparation processes, some of the treatments have a high cost, the materials utilized limit the recyclability of the final system, and in some cases is difficult to scale up the fabrication process [6,7].…”

“…Such materials present advantages due to the large surface-to-volume ratio, but also due to the synergistic effect of the properties of the individual components such as the mechanical properties of the polymeric support and the functionalities of the developed organic or inorganic layers. In particular, hydrophobic-oleophilic or hydrophilic-oleophobic functionalities are introduced on filter paper (FP), polymer films, foams, and textiles [2][3][4][5][6][7][8][9][10][11][12][13][14][15] upon the utilization of macromolecular layers, nano or micro-particles, nanofibers, etc., making these materials able to separate floating oils on water or water-oil emulsions.…”

Superhydrophobic surface on steel substrate and its anti-icing property in condensing conditions

“…A c c e p t e d M a n u s c r i p t 11 condensed water on SHS, the diameter could be very small, and therefore a very large ܲ value could be obtained. As known, such small droplets with high vapor pressure is not easy to contain; thus the amount of water condensed on SHS was not so much compared to that on the bare substrate.…”

“…Inspired by lotus [1][2][3], rose [4,5] and gecko's feet [6], surface with water contact angle (CA) above 150°, has attracted tremendous interest due to the wide application in, for instance, self-cleaning [7,8], anti-corrosion [9,10], oil/water separation [11,12], anti-icing [13] and microfluidic devices [14], etc. Among them, the superhydrophobic surface (SHS) with CA>150° and sliding angle (SA) below 10° is recognized as "lotus effect", on which the droplets maintain a spherical shape and roll off easily.…”
