1. An apparatus for nanomaterial dispersion papermaking comprises:
a housing;
a porous surface, at least a portion of the porous surface being disposed within the housing;
a seal arranged between the porous surface and a sealed portion of the housing, the seal fluidically sealing a porous filter to the sealed portion of the housing;
a plurality of fluid ports disposed adjacent to the porous surface;
a first reservoir of at least one reservoir wherein the first reservoir is coupled fluidically to the plurality of fluid ports, the first reservoir containing a first composition comprising a nanomaterial dispersion, wherein the nanomaterial dispersion comprises a carrier fluid and a suspension comprising at least one nanomaterial carried by the carrier fluid;
a pump arranged to pump the nanomaterial dispersion from the first reservoir to the plurality of fluid ports;
a suction zone arranged in at least a portion of the sealed portion of the housing such that a suction pressure differential induces at least a portion of the carrier fluid of the nanomaterial dispersion to pass through the porous surface, the porous surface separating the at least a portion of the carrier fluid from the suspension when the nanomaterial dispersion is directed to the porous surface, wherein the suspension is incorporated into a mat on the porous surface while the porous surface passes through the suction zone; and
a controller electronically selectively controls fluidic coupling of the first of the at least one reservoirs and the plurality of fluid ports at specific times such that a composition of the mat on the porous surface at specific, three-dimensional locations within the mat formed on the porous surface.
