Superhydrophobic PDMS coated 304 stainless-steel mesh for the removal of HDPE microplastics
نویسندگان
چکیده
The use of microplastics is a global issue that affects the environment, economy and human health. Here we describe superhydrophobic 304 stainless steel obtained by combining chemical etching PDMS modification. Among other techniques, field emission scanning electron microscopy (FE-SEM) high-resolution X-ray photoelectron spectroscopy (HR-XPS) were used to identify hierarchical structure as well composition surface. stainless-steel mesh was (159°) superoleophilic (0°). coating presented high stability against abrasion SiC abrasive paper in presence different pH values acidic or alkaline conditions. In addition, taking advantage coating's wetting properties, show surface can also be remove high-density polyethylene from water. A mechanism promoting removal proposed, considering properties solid pollutants coating.

Compressibility of 304 Stainless Steel Powder Metallurgy Materials Reinforced with 304 Short Stainless Steel Fibers
Powder metallurgy (P/M) technique is usually used for manufacturing porous metal materials. However, some P/M materials are limitedly used in engineering for their performance deficiency. A novel 304 stainless steel P/M material was produced by a solid-state sintering of 304 stainless steel powders and 304 short stainless steel fibers, which were alternately laid in layers according to mass rat...

Nickel films of 150 nm thickness were deposited on 304 stainless steel and post annealed under flow of nitrogen at different temperatures. The prepared samples were corrosion tested in 1.0 M H2SO4 solution using potentiodynamic polarization technique. Crystallographic and morphological structure of the samples were analysed by X-ray diffraction XRD and atomic force microscopy AFM respectively b...
متن کاملMagnetic Properties of Metastable 304 Stainless Steel with Bcc Structure
Ordinary 304 stainless steel has a fcc structure and is non-magnetic at room temperature. By using a vapor quenching method, we have fabricated single-phase metastable bcc 304 stainless steel which is strongly ferromagnetic with a magnetization of 130 emu/g and a Curie temperature in excess of 550 OC. Upon subsequent annealing above 550 OC, the metastable bcc state transforms back into the usua...
متن کاملMicrostructural analysis of expanded stainless steel 304 cylinders
A gas-gun technique to radially expand cylinders of a chosen material, based on a technique developed in 1979, has recently been re-established. Stainless steel 304 cylinders of length 160 mm, internal diameter 67 mm and thickness either 0.5 or 1.5 mm have been expanded using a 70 mm bore single-stage gas-gun. Microstructural analysis of the recovered specimens was performed using optical micro...
