“…Thus, developing superamphiphobic surfaces that are both superhydrophobic and superoleophobic has received considerable attention because of the wider applications for the engineering of robust anticontamination, antisticking, and self-cleaning material in general. [32][33][34][35][36] Cast iron is a very important material with wide applications in our daily life and industry fields. However, most common cast iron-based materials rust easily in a humid ambient environment, which is likely to decrease its useful lifetime in practical applications.…”

A superamphiphobic (super-repellent) surface with both water and rapeseed oil contact angle higher than 150°was prepared on a common cast iron substrate. The water and rapeseed oil contact angles were 158 ± 1.9°and 151 ± 1.7°, respectively. The sliding angles of water and rapeseed oil on the superamphiphobic surface were 2°and 16°, respectively. Scanning electron microscope images showed that many interesting microflower-like microstructures comprised many nanorods with the average diameter of about 200 nm, which were distributed on the superamphiphobic cast iron substrate. Each nanorod was composed of many smaller nanostructures and nano particles, which created interesting micro-nano binary structures similar to the surface microstructures of lotus leaves. When kept in an ambient environment for 6 months, no rust was observed on the superamphiphobic cast iron substrate surface, which showed excellent corrosion resistance.

“…Coating mesoporous silica on SG enables the sorbent to exert a high efficiency; MSG0.5 adsorbed 59% of nitrosamines while MSG2.5 trapped 54%, exceeding all other porous samples. Besides, they also 12 exhibited the high activity in adsorption of TSNA in tobacco solution, and about 30% of the carcinogens were removed. Capture of TSNA in tobacco extract solution is very hard because the bulky TSNA molecule is difficult to be adsorbed but easy to desorb [2].…”

“…TSNA are oily molecules and their adsorption in tobacco extract solution is inevitably interfered by water [1], so the favorable separation performance between water and oil is vital. Nowadays, many porous hydrophobic materials have been extensively studied [5], including carbon based materials [6], metal oxide nanowires [7,8], biological nanometer fiber [9,10], organic polymer [11,12] and macroporous aerogel [13][14][15], etc. However, complex synthesis and high cost hinders their actual application.Recently, hydrophobic polymethylsilsesquioxane (PMSQ) materials have been synthesized by crosslinking polymerization of methyltrimethoxysilane (MTMS), in which mesopores and macropore could be produced through phase separation [16,17].Also, flexible marshmallow-like silicic aerogel/xerogel was synthesized from MTMS and dimethyldimethoxysilane (DMDMS) co-precursor [18].…”

Super-hydrophobic silicic xerogel (SG) was prepared from methyltrimethoxysilane (MTMS) and dimethyldimethoxysilane (DMDMS), and the optimized MTMS to DMDMS molar ratio was determined to be 3/2. To fabricate new effective nitrosamines sorbent in tobacco extract solution, SG was modified by epitaxial growth of mesoporous silica to form the coated composite named as MSGx with a large surface area (152-208 m 2 g -1 ) and pore volume (0.133-0.162 mLg -1 ), and the new sorbent could capture 54~59% of nitrosamines in tobacco solution, superior to zeolite and mesoporous silica. 1 IntroductionNitrosamines are deemed to be the widespread carcinogens characterized with N-nitroso group, including volatile nitrosamines (VNA), non-volatile nitrosamines and tobacco specific nitrosamines (TSNA). TSNA are a group of carcinogens found only in tobacco products. They can cause various cancers or tumors in laboratorial animals and possess the potential carcinogenicity to human though their content in tobacco and tobacco products is in the range of μg g -1 (ppm) or ng g -1 (ppb). Among various efforts controlling the pollution of nitrosamines in environment, one strategy is to adsorb TSNA in tobacco extract solution in order to reduce the injurant at source [1][2][3][4], and effective sorbent is the key. TSNA are oily molecules and their adsorption in tobacco extract solution is inevitably interfered by water [1], so the favorable separation performance between water and oil is vital.

“…It is well-known that the methods to fabricate a superhydrophobic surface can be mainly reduced to two approaches: either create a rough structure on a hydrophobic material surface or modify the rough surface with a special low surface energy material [16,17]. In the experiment reported here, we created a rough structure on the Al substrate and then modified the rough surface with a special low surface energy material.…”
