WATER-SWELLING LAYERED DOUBLE HYDROXIDE, METHOD FOR PRODUCING SAME, GEL OR SOL SUBSTANCE, DOUBLE HYDROXIDE NANOSHEET, AND METHOD FOR PRODUCING SAME

摘要

Provided is a water-swelling layered double hydroxide characterized by having an organic sulfonic acid anion (A - ) between layers, and by being represented by the belowmentioned general formula (1): Q z R(OH) 2(z+1) (A - ) (1-y) (X n- ) y/n ·mH 2 O...(1). Here, Q is a divalent metal, R is a trivalent metal, A - is an organic sulfonic acid anion, m is a real number greater than 0, and z is in the range of 1.8‰¤z‰¤4.2. X n- is the n-valent anion remaining without A - substitution, n is 1 or 2, y represents the remaining portion of X n- , and 0‰¤y0.4.
