Abstract
Sposób wytwarzania warstwy grafenu z matrycy ciekłego metalu na stałym podłożu metalowym lub ceramicznym charakteryzuje się tym, że płytę wielowarstwową, zawierającą, jako matrycę formującą grafen, warstwę zewnętrzną metalu lub stopu metali o temperaturze topnienia w przedziale od 1051°C do 1150°C oraz, jako podłoże, od 1 do 5 warstw z metali przejściowych i/lub ich stopów i/lub metaloidów i/lub ich roztworów oraz związków o temperaturach topnienia w przedziale od 1151°C do 3410°C, obrabia się termicznie w następujących etapach: - nagrzewanie do momentu osiągnięcia przez płytę temperatury od 0,5°C do 50°C powyżej temperatury topnienia matrycy formującej, - wygrzewanie w stałej lub zmiennej temperaturze z tego zakresu przez okres od 60 do 600 sekund, dozując przy tym do atmosfery acetylen przy ciśnieniu cząstkowym od 0 do 4 hPa, etylen przy ciśnieniu cząstkowym od 0 do 4 hPa oraz wodór przy ciśnieniu cząstkowym od 0 do 2hPa przez czas od 10 do 300 sekund, - schładzanie, w części kontrolowane, podczas którego, w przedziale temperatur od 1200°C do 1050°C, utrzymuje się szybkość schładzania w zakresie od 0,1 do 2°C/min, przy czym poszczególne etapy nagrzewania, wygrzewania oraz schładzania przeprowadza się w atmosferze czystego argonu o stałym ciśnieniu cząstkowym z zakresu od 1 hPa do 1100 hPa.The method of producing a graphene layer from a matrix of liquid metal on a solid metal or ceramic substrate is characterized by a multilayer plate containing, as a matrix forming graphene, an outer layer of metal or metal alloy with a melting point in the range from 1051°C to 1150°C and, as a substrate, from 1 to 5 layers of transition metals and/or their alloys and/or metalloids and/or their solutions and compounds with melting points ranging from 1151°C to 3410°C, thermally treated in the following stages: - heating until the plate reaches a temperature of 0.5°C to 50°C above the melting temperature of the forming matrix, - heating at a constant or variable temperature in this range for a period of 60 to 600 seconds, while dosing acetylene into the atmosphere at a partial pressure from 0 to 4 hPa, ethylene at a partial pressure of 0 to 4 hPa and hydrogen at a partial pressure of 0 to 2 hPa for a period of 10 to 300 seconds, - cooling, partly controlled, during which, in the temperature range from 1200°C to 1050 °C, the cooling rate is maintained in the range of 0.1 to 2°C/min, with the individual stages of heating, annealing and cooling carried out in an atmosphere of pure argon with a constant partial pressure in the range from 1 hPa to 1100 hPa.
