Solid-liquid bi-phase lubricating devices and methods of using same

A lubricating device comprising:

• an encasing member, wherein the encasing member comprises a polymer composite, an outer surface, an inner surface, an inner space, an opening, a first end, and a second end, wherein the polymer composite has a hardness of about 20 to about 70 units in Shore D hardness scale;
• wherein the polymer composite comprises less than 40 wt % of a polymer;
• and
• a lubricating composition, wherein the lubricating composition is disposed on the inner surface of the encasing member,
• wherein the lubricating composition further comprises one or more inorganic solid lubricants, wherein the one or more inorganic solid lubricants is selected from a list comprising a graphene platelet, graphene oxide, 2D boron nitride, MXene, graphite, molybdenum disulfide, tungsten disulphide hexagonal boron nitride, and polytetrafluoroethylene particles, and wherein the lubricating composition has a weight percent of the one or more inorganic solid lubricants from about 0 wt % to about 10 wt %, and
• wherein the polymer composite comprises at least one of a thermoplastic or thermosetting polymer.
