METHOD FOR PEELING LAYERED DOUBLE HYDROXIDE, DOUBLE HYDROXIDE NANOSHEET, COMPOSITE THIN FILM MATERIAL THEREOF, METHOD FOR PRODUCING THE SAME, AND METHOD FOR PRODUCING LAYERED DOUBLE HYDROXIDE THIN FILM MATERIAL

摘要

PPROBLEM TO BE SOLVED: To provide a method for easily peeling an LDH having inorganic anions as an intermediate layer, and to provide a double hydroxide nanosheet obtained thereby. PSOLUTION: The method for peeling a layered double hydroxide comprises a process where a layered double hydroxide is mixed with an aprotic polar organic solvent. The layered double hydroxide is represented by any of [MSP2+/SPSB1-x/SBMSP3+/SPSBx/SB(OH)SB2/SB]SPx+/SP[ASPn-/SPSBx/n/SB-mHSB2/SBO]SPx-/SP(1), [LiSP+/SPSB1-x/SBMSP3+/SPSBx/SB(OH)SB2/SB]SP(2x-1)+/SP[ASPn-/SPSB(2x-1)/n/SB-mHSB2/SBO]SP(2x-1)-/SP(2), and [MSP2+/SPSB1-x/SBTiSP4+/SPSBx/SB(OH)SB2/SB]SP2x+/SP[ASPn-/SPSB2x/n/SB-mHSB2/SBO]SP2x-/SP(3), wherein, MSP2+/SPis a bivalent metal ion; MSP3+/SPis a tervalent metal ion; ASPn-/SPis an inorganic anion selected from the group consisting of NOSB3/SBSP-/SP,ClSP-/SP, ClOSB3/SBSP-/SP, ClOSB4/SBSP-/SP, FSP-/SP, BrSP-/SP, ISP-/SP, COSB3/SBSP2-/SP, SOSB4/SBSP2-/SPand their mixture; n is the bivalent of the inorganic anion; m is a real number larger than 0; and x satisfies 0x0.5.
