Construct a stable super-hydrophobic surface through acetonitrile extracted lignin and nano-silica and its application in oil-water separation

Preparation of lignin nanospheres based superhydrophobic surfaces with good robustness and long UV resistance

“…This was because lignin as the main material contains large numbers of benzene rings, carbonyl, double bonds, and other conjugated structures, which are good for absorption of UV light. 30 Both the LNPs/P and LNPs/C/P coatings showed similar results, indicating that CNC mainly affected the strength of coating and had no effect on UV resistance. However, with increase of UV radiation time, the WCAs kept falling and the slide angles kept rising.…”

“…29 There are also scholars preparing a highly efficient superhydrophobic coating on a lter paper with SiO 2 and lignin extracted by acetonitrile. 30 However, the study on UV resistance, enhancement of wear resistance, and systematic characterization on lignin-based superhydrophobic surfaces is lacked in the reports. LNPs have a natural advantage in the development and application of superhydrophobic surfaces due to the low content of active hydroxyl group and excellent UV resistance, 31 which is benecial to prevent substrates from aging to some extent.…”

Nano-biotechnology, an applicable approach for sustainable future

“…Gas and oil products can be cleaned from H 2 S by applying nanomaterials (Agarwal and Sudharsan 2021). Utilizing starch nano coatings (Wang et al 2021), Lignin and nano-silica (Gong et al 2021), Lotus leaf coated with nano-SiO 2 (Yang et al 2021), and nano zeolite membrane are new methods for the separation of oil and water due to their high hydrophobic property (Anis et al 2021). Nanotechnology can be used to improve the quality of engine oil, which results in the better stability and lubricity power as well as a reduced rate of released carbon mono oxide (Tonk 2021;Saidi et al 2021;Thirugnanam et al 2021;Ardebili et al 2020).…”

Thermal fluctuation and conformational effects on NMR parameters in β-O-4 lignin dimers from QM/MM and machine-learning approaches

“…Differently substituted monolignol subunits are derived from coniferyl, pcoumaryl, and sinapyl alcohols To capture the effect of those flexible β-O-4 structures on NMR parameters we considered five different solvents: pure water, ethanol (EtOH), acetonitrile (ACN), and 75wt% water-ethanol and water-acetonitrile mixtures. These solvents have been chosen because they were recently proposed for lignin fractionation with original properties in organosolv processes [35][36][37] . In particular, aqueous ethanol is among the most used alcoholic organic solvent in comparison to the other alcohols employed in the organosolv pulping of lignocellulosic biomass in biorefinery [37][38][39][40][41] .…”
