functional groups. The action mechanism of functional group to morphology was also proposed. Key words: 1-octadecanol; stearic acid; oleic acid; Gibbsite morphology; functional group 1 Introduction... the influence of alditols and hydroxy-carboxylic acids[4]. However, there is no report about the exact effect of mono functional group on the gibbsite morphology. In this study, effect of organic......
