▎ 摘　　要

NOVELTY - The separating method involves applying voltage at least between working electrode, which is conducting substrate-graphene-support layer laminate and at least one of counter electrodes. The voltage between the working electrodes, which is conducting substrate-graphene-support layer laminate, and at least one of the reference electrodes is measured, such that graphene-support layer laminate separates from conducting substrate. USE - Separating method for N-electrode electrochemical system (claimed) used in separating graphene-support layer laminate from conducting substrate-graphene-support-layer laminate. ADVANTAGE - By measuring voltage between working electrodes, which is conducting substrate-graphene-support layer laminate, and reference electrodes, such that graphene-support layer laminate separates from conducting substrate, substrates which are fragile, expensive or difficult to manufacture can be used, and even be re-used, without damage or destruction of substrate or graphene. DETAILED DESCRIPTION - The support layer is a polymer layer, suitable selected from para-Methoxy-N-methylamphetamine, cellulose acetate butyrate, polystyrene, polyvinyl chloride, polyvinyl alcohol or co-polymers. An INDEPENDENT CLAIM is also included for a N-electrode electrochemical system.
