Abstract Scope |
The electrical conductivity of lunar regolith affects the performance predictions for electro-chemical reactors and plays a role in simulating geophysical aspects of lunar interior. For solid lunar regolith, the electrical conductivity is expected to be close to zero. To improve the electrical conductivity of lunar regolith addition of graphene nanoplatelets (GNP) is proposed in the present study. Greenland Anorthosite lunar regolith simulant (Al2O3, SiO2, and Al2SiO5 as major phases) reinforced with varying content of GNP (0 to 5 vol.%) was three-dimensional (3D) printed using Digital Light Processing (DLP). Two step debinding process is designed for the removal of resin in a way to avoid oxidation reaction in GNP followed by pressureless sintering. Further, microstructural and electrical characterizations were carried out to establish structure-property correlation. This research endeavor is an important step towards studying the functionality of 3D printed lunar regolith parts with graphene nanoplatelets. |
