NOVELTY - A graphene nanoribbon (GNR) (2) network membrane (1) comprises several graphene nanoribbon(s) arranged at an angle of an integral multiple of 60 degrees with each other. The graphene nanoribbon(s) are sp2 orbital hybrid six-membered ring junction with each other. USE - Graphene nanoribbon network membrane used for forming electronic device (claimed). ADVANTAGE - The graphene nanoribbon network membrane has excellent charge mobility. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) manufacture of the graphene nanoribbon network membrane, which involves depositing a graphene nanoribbon precursor of formula (I) on the (111) plane of a metal film having a face-centered cubic lattice at a temperature (t1), heating a graphene nanoribbon precursor at a temperature (t2) more than the temperature (t1) on the (111) plane to induce elimination of X and a CC binding reaction on the (111) plane, and obtaining a polymer on the (111) plane, heating the polymer at a temperature (t3) more than the temperature (t2) to induce elimination of Y and a CC bond reaction, heating the polymer at a temperature (t4) more than the temperature (t3) and inducing elimination of Z and CC binding reaction, obtaining several graphene nanoribbon(s) arranged on the (111) plane at an angle of an integral multiple of 60 degrees , and heating the graphene nanoribbon(s) at a temperature (t5) more than the temperature (t4), joining the graphene nanoribbon(s) to each other with a six-membered ring junction of sp2 orbital hybrids, and realizing the desorption temperatures of X, Y, and Z from the carbon atoms that make up the six-membered ring are Tx and Ty more than the Tz; (2) an electronic device, which consists of the graphene nanoribbon network film in a channel of a field effect transistor; and (3) manufacture of the electronic device, which involves producing the graphene nanoribbon network film on the (111) plane of the metal film, and forming the field effect transistor containing the graphene nanoribbon network film in a channel. n1,n2 = 1-6;and X,Y',Z' = F, Cl, Br, I, H, OH, SH, SO2H, SO3H, SO2NH2, PO3H2, NO, NO2, NH2, CH3, CHO, COCH3, COOH, CONH2, COCl, CN, CF3, CCl3, CBr3 or CI3.
