Electromagnetic shielding material, a connector shielding shell and a cable

An electromagnetic shielding material comprising raw materials in part by weight:

• 1 part of surfactant, 1 part of coupling agent, 1 part of reductant-oxidant, 1-3 part(s) of dispersant, 5 parts of silver, 1 part of carbon, 47-50 parts of graphene oxide, 40 parts of thermoplastic elastomer and 0.2-1 part of lubricant;
• wherein the surfactant is selected from sodium dodecyl benzene sulfonate, sodium dodecyl sulfate, hexadecyl trimethyl ammonium bromide, butynediol diethoxy ether and polyvinylpyrrolidone;
• the dispersant is selected from polyethylene glycol octylphenyl ether, ethylene bis-stearamide and organic silicone oil;
• and the thermoplastic elastomer is selected from urethane, olefin, amide, diene and organic silicon thermoplastic elastomer.

A cable comprising:

• an outer sheath;
• an inner sheath;
• and
• an outer shielding layer disposed between the outer sheath and the inner sheath;
• wherein the inner sheath includes a differential signal cable in an interior of the inner sheath;
• wherein the outer shielding layer employs plastic materials synthesized by using graphene oxide;
• wherein the outer shielding layer is prepared from raw materials in part by weight:
• 1 part of surfactant, 1 part of coupling agent, 1 part of reductant-oxidant, 1-3 part(s) of dispersant, 5 parts of silver, 1 part of carbon, 55 parts of graphene oxide, 40 parts of thermoplastic elastomer and 0.2-1 part of lubricant;
