Preparation method for organic-inorganic layered compounds including fibrous materials by the reaction of Zn(OH)(2) with organic compounds

A preparation method of surface modified inorganic layered compounds includ ing fibrous materials was established by the reaction of amorphous Zn(OH)(2 ) with organic oxychlorides. The resultant layer structures were similar to those of the layered double hydroxides (LDHs). Although the LDH layers hav e positive charges the layers; of the reaction products obtained here are u ncharged. IR spectra indicate that hydroxyl groups reacted with the organic oxychlorides, and new peaks assigned to RCO2-Zn bonds appeared around 1400 and 1550 cm(-1) and 40-98% of hydroxyl groups were reacted. Interlayer spa cings of the reaction products of Zn(OH)(2) with dioxychlorides were 0.71-1 .48 nm, and those of Zn(OH)(2) with monooxychlorides were 1.19-2.67 nm and- depended on the length of organic compounds. SEM images showed that the rea ction products of Zn(OH)(2) with organic oxychlorides had plate-like morpho logy similar to LDHs. However, the reaction product of Zn(OH)(2) with benzo yl chloride was fibrous.
