摘要： Embodiments of the invention provide a composite material having sufficient strength to form structural components of an aerospace vehicle, while also having sufficient electrical conductivity to dissipate electrostatic charge. As such, a composite material comprises an imide oligomer having thermally reactive endcaps and carbon nanofillers. The imide oligomer may comprise a phenyl ethynyl terminated imide. The phenylethynyl terminated imide may have a molecular weight of less than about 5000, or may have a molecular weight in the range of about 250 to about 5000. In particular, the phenylethynyl terminated imide may have a molecular weight of about 1500. The carbon nanofillers may be selected from the group consisting of carbon nanotubes, carbon nanofibcrs, expanded graphite, exfoliated graphite and combinations thereof. The carbon nanotubes may be selected from the group consisting of single-walled carbon nanotubes, double-walled carbon nanotubes, multi-walled carbon nanotubes and combinations thereof.

摘要： A fluid-control electro-active device includes a piezo-diaphragm made from a ferroelectric material sandwiched by first and second electrode patterns configured to introduce an electric field into the ferroelectric material when voltage is applied thereto. The electric field originates at a region of the ferroelectric material between the first and second electrode patterns, and extends radially outward from this region of the ferroelectric material and substantially parallel to the plane of the ferroelectric material. The piezo-diaphragm deflects symmetrically about this region in a direction substantially perpendicular to the electric field. An annular region coupled to and extending radially outward from the piezo-diaphragm perimetrically borders the piezo-diaphragm. A housing is connected to the annular region and defines at least one fluid flow path therethrough with the piezo-diaphragm disposed therein.
