Abstract
A hydrophilized material has a surface provided with surface roughness that arithmetic mean roughness is 0.3 μm to 1.0 μm and mean width of roughness profile elements is 0.1 mm or less. A hydrophilized member that contacts a liquid is at least partially made of the hydrophilized material. The hydrophilized member is applicable to a gas-liquid contact apparatus having a gas-liquid contact section, a liquid supply system, and a gas supply system, to constitute the gas-liquid contact section as a packing element. Wettability imparted due to the surface roughness is exhibited continuously.
