1. A method for isolating a flexible film from a support substrate, comprising:
providing a support substrate with a top surface; subjecting the top surface of the support substrate with a surface treatment, thereby forming a top surface with detachment characteristics; forming a flexible film on the top surface of the support substrate; and isolating the flexible film from the support substrate, wherein the surface treatment comprises providing a chemical agent to react with the top surface of the support substrate; and wherein the chemical agent has the structure represented bywherein W is C, Si, or Ge; X is S, or Se; Y is C, or S; R1, R2, and R3 are independent and comprise H, alkenyl group, alkyl group, or —OR; R is C1-18 alkyl group; R4 is F, Br, I, carboxyl group, amino group, amine group, cyano group, amide group, alkyl halide group, or combinations thereof; R5 is Li; and R6, R7, and R8 are independent and comprise F, Cl, Br, I, alkenyl group, alkyl group, carboxyl group, amino group, amine group, cyano group, amide group, alkyl halide group, or combinations thereof. |
