Abstract
An object of the present disclosure is to provide a composition having excellent stability of a refrigerant. Provided is a composition comprising a refrigerant and carbon, the refrigerant comprising at least one member selected from the group consisting of HFO-1234yf, HFO-1132(E/Z), HFO-1132a, HFO-1123, and FO-1114.
Claims7
A composition comprising a refrigerant and carbon,
- the refrigerant comprising at least one member selected from the group consisting of trans-1,2-difluoroethylene (HFO-1132(E)), cis-1,2-difluoroethylene (HFO-1132(Z)), 1,1-difluoroethylene (HFO-1132a), trifluoroethylene (HFO-1123), and tetrafluoroethylene (FO-1114), and
- the carbon is at least one particle selected from the group consisting of carbon fibers, carbon nanotubes, graphene, and amorphous carbon.
A method for stabilizing a composition comprising a refrigerant,
- the refrigerant comprising at least one member selected from the group consisting of trans-1,2-difluoroethylene (HFO-1132(E)), cis-1,2-difluoroethylene (HFO-1132(Z)), 1,1-difluoroethylene (HFO-1132a), trifluoroethylene (HFO-1123), and tetrafluoroethylene (FO-1114), and
- the method comprising incorporating carbon into the composition,
- the carbon is at least one particle selected from the group consisting of carbon fibers, carbon nanotubes, graphene, and amorphous carbon.
