1. A polymeric composite material comprising:
a continuous polymeric matrix comprising a thermoset polymer or a blend of thermoset polymers, wherein the thermoset polymer or blend of thermoset polymers include polyester, epoxy, or nylon; and
a discontinuous phase comprising a plurality of polymeric aerogel particles dispersed within the continuous polymeric matrix, wherein the plurality of aerogel particles are polyimide aerogel particles,
wherein polyimide from the plurality of polymeric aerogel particles is in direct contact with the continuous polymeric matrix,
wherein the thermal conductivity (W/m·K) of the polymeric composite material is lower when compared with the same polymeric composite material that does not include the discontinuous phase comprising the plurality of polymeric aerogel particles, and
wherein the dielectric constant of the polymeric composite material is decreased when compared with the same polymeric composite material that does not include the discontinuous phase comprising the plurality of polymeric aerogel particles.
