A membrane modification method for improving liquid membrane separation of carbon dioxide (CO) includes grafting an organic substance containing an amine group on a porous membrane material, and loading water into pore channels of the porous membrane material to prepare a supported liquid membrane for a gas mixture separation experiment of CO. In the method, the amine group is introduced through chemical grafting to make the water being alkaline when used as membrane liquid. Compared with an alkaline solution as the membrane liquid, the method can avoid the loss of active alkaline substances and increase the permeation flux of CO.

Modified porous membrane material and preparation method thereof, and liquid membrane separation method of carbon dioxide

A vent filter and a Radio Remote Unit having the vent filter. The vent filter includes a first member including a first body having a ventilation path extending through the first body, an inner wall constituting a ventilation hole which is communicated with the ventilation path, and an outer wall constituting a gap between the inner wall and the outer wall. The vent filter also includes a second member including a second body and at least one enclosure wall protruding out from the second body, wherein at least one of the at least one enclosure wall is located outside the outer wall and surrounding the outer wall. Both the inner and outer walls have at least one first groove at an end and each of the at least one enclosure wall has at least one second groove at an end.
