A thin alumina‐hydrotalcite (Al‐HT) film was fabricated from the synthesized boehmite and HT sol samples. The sols were a Newtonian fluid within 12 h of the sol synthesis and pseudo‐plastic flow thereon. Co‐precipitated HT demonstrated poorly crystallized periclase and spinel structures and apparent doublet peak of hydrotalcite at 2θ = 39–44°, indicative of a disordered structure. The heated Al‐HT sample demonstrated highly amorphous structure with single hydrotalcite peak but barely observed γ‐alumina and γ‐boehmite phases. The exfoliation of the spinel, gibbsite and periclase in the Al‐HT was caused by the intercalation of boehmite into the HT layers that impeded the formation of the oxides phases.
