Abstract: A super-wet surface is a polypropylene surface, on which a hydrophilic side group is grafted, having a micro-nano structure. The super-wet surface is at least super-hydrophilic and does not contain an initiator residue. The super-wet surface is prepared by grafting, in the absence of an initiator, by means of microwave irradiation, a monomer for forming a side group, on the polypropylene surface, as a grafting base, having a micro-nano structure. In the preparation of the super-wet surface, the molecular weight of polypropylene does not decrease after grafting, there is no residual monomer or initiator residue, and the super-wetting effect of the obtained surface is lasting and stable. The super-wet surface can be used in bonding, spraying, oil-water separation, water treatment, biology, medicine and energy fields.

Abstract: A porous composite material capable of generating an arc in a microwave field includes an inorganic porous framework and a carbon material loaded on the inorganic porous framework. The average pore size of the inorganic porous framework is 0.2-1000 ?m. The porous composite material has an excellent mechanical performance, can generate an arc in a microwave field to quickly generate a high temperature, and thus can be used in fields such as microwave high-temperature heating, biomass pyrolysis, vegetable oil treatment, waste polymer material pyrolysis, petrochemical pyrolysis, carbon-fiber composite material recovery, waste treatment, VOC waste gas treatment, COD wastewater treatment, high-temperature catalysis, waste circuit board full-component recycling, and hydrogen preparation.

Abstract: Provided is a solid wire for gas metal arc welding, which has a small amount of fume during welding and is suitable as a welding material for high Mn steel materials. The wire has a chemical composition containing, in mass %, C: 0.2% to 0.8%, Si: 0.15% to 0.90%, Mn: 17.0% to 28.0%, P: 0.03% or less, S: 0.03% or less, Ni: 0.01% to 10.00%, Cr: 0.4% to 4.0%, Mo: 0.01% to 3.50%, B: less than 0.0010%, and N: 0.12% or less, with the balance consisting of Fe and inevitable impurities. It may contain at least one selected from V, Ti, Nb, Cu, Al, Ca and REM, if necessary. The wire has excellent manufacturability, can significantly suppress the amount of fume generated during gas metal arc welding, and can easily manufacture a weld joint having high strength and excellent impact toughness at cryogenic temperatures.
