A recently granted patent (Publication Number: US11840799B2) discloses a mesh member that includes a mesh woven fabric made of warps and wefts, along with a coating layer containing single-wall carbon nanotube and/or graphene. The coating layer is applied to the surfaces of the fibers comprising the warps and wefts. The mesh member can function as a sieving net or a screen fabric, with the weave of the mesh woven fabric being a plain weave, twill weave, or sateen weave.

Furthermore, the patent claims specify that the coating layer on the mesh member should have a thickness ranging from 0.1 µm to 1.0 µm and a volume resistivity between 0.01 O·cm and 1×108 O·cm. Additionally, variations of the mesh member include being specifically designed as a sieving net or a screen fabric, with potential applications in sieves and screen printing plates. The mesh member can also be constructed using resin fibers for the warps and wefts, with the coating layer applied to their surfaces, enhancing the overall functionality and durability of the mesh member.
