Taschenbuch. Condizione: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - Stearate anions (SA) were successfully intercalatedinto a layered double hydroxide (LDH-CO3) to formLDH-SA. The intercalation method involved theacid-base reaction between emulsified stearic acidand carbonate anions in aqueous media. This methodled to the formation of more LDH-SA than well knownmethods such as melting the carboxylic acid in thepresence of the LDH, allowing the interlayer regionto swell in the presence of glycerol andreconstructing the calcined LDH in the presence ofaqueous sodium stearate. Other literature methodsinvolve ion-exchange of chloride in LDH-Cl withstearate in aqueous sodium stearate, usually undernitrogen atmosphere. The LDH-SA was successfully usedto intercalate sodium polyvinyl sulphonate by an ionexchange with the intercalated stearate, without theneed for a nitrogen atmosphere. The sameintercalation reaction was allowed to take place insitu during the formation ofdextrin-alginate-glycerol film solutions inwater-ethanol media. The stearate intercalated as abilayer in the interlayer region of the LDH. Thisreduced the water vapour permeability of the films.…
