A glucose modified filter paper for effective oil/water separation

Abstract

Toluene/water emulsion cannot be separated by the un-treated filter paper. In comparison, toluene/water emulsion could be efficiently separated by the glucose (GLC) treated filter paper.

Facile Fabrication of a Mechanical, Chemical, Thermal, and Long‐Term Outdoor Durable Fluorine‐Free Superhydrophobic Coating

“…[ 1,2 ] The easy roll‐off of water droplets on super‐hydrophobic surfaces is called the “lotus effect.” A super‐hydrophobic surface is a surface with a water contact angle (WCA, θ) greater than 150° and a rolling or sliding angle smaller than 10°. [ 3 ] Due to their special properties, super‐hydrophobic surfaces can become self‐cleaning, [ 4 ] anti‐reflective, [ 5,6 ] microfluidic transmissive, [ 7,8 ] corrosion resistant, [ 9,10 ] oil–water separating, [ 11,12 ] antibacterial, [ 13 ] and anti‐icing. [ 14,15 ] The preparation methods of super‐hydrophobic coatings mainly include hydrothermal, [ 16 ] template, [ 17 ] sol–gel, [ 18 ] etching, [ 19 ] magnetron sputtering, [ 20 ] electrodeposition, [ 21 ] self‐assembly, [ 22 ] chemical vapor deposition, [ 23 ] etc.…”

Wood‐Derived Systems for Sustainable Oil/Water Separation

“…It is organized by microsized pulp fibers. Paper such as filter paper is generally used as a substrate for integration with active components such as glucose, [42] polyvinyl alcohol (PVA), [40] and tunicate CNC, [77] to fabricate hydrophilic composite paper with ultrafine pores that allowing water to pass while retaining oil. PVA hydrogel-coated filter paper can be produced by crosslinking the paper with PVA (Figure 3a).…”

“…Because they contain numerous hydroxyl groups and comprise chemical components with relatively high carbon contents, these wood-derived materials can be further processed into novel bulk materials of specific wettability and roughness, and with pore structures that are useful for oil/ water separation. Thanks to the efforts of numerous research groups, a series of wood-derived materials-such as delignified wood blocks, [37,38] wood pulps, [39] filter papers, [40][41][42] films/membranes, [43,44] aerogels/foams/sponges, [45][46][47] and carbon-based bulk materials [48,49] -have been produced and used in oil/water separation systems. The separation speed, separation efficiency, antifouling performance, and reusability of such systems are critical for practical and sustainable applications.…”

Biodegradable Filter Paper Based Broad-Band Photodetection by Chemical Bath Deposited SnS2 2D-Nanosheet Array Film

“…Using a technique that can easily yield an active semiconducting film over a large area of a paper is the key to producing cheap photodetectors with the so-called biodegrading properties. 13,14 Success of this biodegradable paper based photodetector can create one more way to stop the electronic wastage phenomenon from expanding even more. Since use of broad-band photodetectors is rapidly expanding in our daily life as well as in various sophisticated applications such as communication technology, military usage, bioimaging, camera sensors, and automatic doors, etc., 15−20 paper based ecofriendly broad-band photodetectors may add huge benefits to society.…”

“…Additionally, easy availability and nontoxicity can lead them to be emergent in future intelligent electronics. , Due to the above-mentioned unique characteristics, the paper based biodegradable optoelectronic devices are attracting attention for various applications, including gas sensing, energy storage, and photodetection, etc. − Biodegradable paper based photodetector uses a combination of paper and active semiconducting material that can detect light of required wavelength.
