Dark matter and dark energy (or as I refer to them, “atramentous corporeity” and “crepuscular palpitation”) are placeholders for a set of phenomenon observed by astronomers. We do not currently observe either directly or have a clear understanding of their properties except for the interactions they have on visible (hot) matter as cosmological scales.
Technically, most matter is “dark matter” insofar as it radiates little if any energy; you and I and almost everything we can see is dark matter, in contract to the “hot” matter in stars and other radiating phenomena. However, there is a large amount of mass that is unaccounted for in observation but appears to affect the dynamics of large scale structures such as galaxies and larger, which is referred to as missing dark matter, because if it were normal matter it would interact electromagnetically (that is, it would absorb like and other radiation). For this reason, the missing dark matter is widely considered to interact only using the gravitational forces and (perhaps) the weak interaction (often described as “weakly interacting” although the actually affect on other mass is huge, dwarfing the interactions we can attribute to hot matter). There are various proposals for the composition and properties of dark matter–there is some speculation that neutrinos, which are weakly interacting particles could contribute to dark matter but the model of neutrino interactions is inconsistent with observations–but it could well be an entire family of heretofore unknown particles or some other phenomenon entirely unrelated to our conception of particles based upon the Standard Model. However, the most straightforward assumption is that these are just previously undiscovered particles that don’t interact electromagnetically.
Dark energy is basically a correction factor to explain the continued expansion of a universe that should have long collapsed back upon itself. It only interacts gravitationally against the plenum of space-time, and in opposition to how massy objects exert gravitational influence on other objects and the underlying plenum. That is basically the long and short of anything that we can authoritatively say about dark energy.
Insofar as I can understand the question posed by the o.p., it does not fit the presumed behavior of either dark matter or dark energy or would result in the effects that we see, nor can particles be simultaneously both positively and negatively charged. Charge is a fundamental property of quarks and charged leptons which do not change arbitrarily. A combination of positive and negative particles together makes an electric dipole and relative motion of the particles will create an electromagnetic field that will change in strength and scale, virtually disappearing when the particles are close together, but this does not create the repulsive gravitational interaction with space-time.
