Patent ID: 8708135

Claim:
A media vacuum transport system comprising: a vacuum plenum; one or more transport members configured to rotate around the vacuum plenum, wherein at least one of the one or more transport members comprises: a substrate, the substrate comprising a plurality of holes extending from a first side proximate to the vacuum plenum to a second side proximate to the media, the substrate comprising a material selected from the group consisting of polyethylene terephthalate (PET), polyethylene naphthalene (PEN), polysulfone (PS), polyimide (PI), polyamideimide (PAI), and polyetherimide (PEI), and a top coat layer disposed over the substrate, wherein the top coat layer comprises a plurality of hollow micro spherical particles dispersed in a resin selected from the group consisting of polycarbonate, polyester and polyarylate, the hollow micro spherical particles having a diameter ranging from about 15 μm to about 100 μm to provide an average surface roughness Ra of about 8 μm to about 100 μm, and wherein the top coat layer further comprises electrically conductive fillers chosen from carbon black, graphene, carbon nanotubes or metal particles, the hollow micro spherical particles being dispersed throughout substantially the entire thickness of the top coat layer.
