Were dealing with nanotechnology here, the nanotech foglets can link together
and optimise themselves to reflect sunlight. The sunlight that is reflected is
not absorbed. Naturally no surface is perfectly reflective and it will absorb
some heat. The material will be partially transparent as well so that some
sunlight will reach Venus's surface. The foglets will be designed to reflect
the excess sunlight however to provide Earthlike conditions on the surface.

The foglets can use the atmosphere to support themselves. They link together
for maximum reflectence when they reach the optimum altitude, if they move out
of that altitude, they separate and act as ordinary dust particles until the
air currents bring them back up the the proper altitude once again. the
atmosphere can support plenty of particles, similar sized particles make the
sky of Mars pink and are supported by an atmosphere much thinner than Earth's.
No electrostatic trickery is required.
