Abstract
Hydro-thermal method was used to prepare semi-hydrated calcium sulfate whiskers with sodium oleate as surfactant during the process of preparation and modification integration of calcium sulfate whiskers. Electronic biological microscope was adopted to observe the morphology of semi-hydrated calcium sulfate whiskers. FTIR was used to analyze the surface state of unmodified and modified semi-hydrated calcium sulfate whiskers. The experimental results showed that when the dosage of sodium oleate is less than 0.02%, the morphology of whiskers appears to be fibrous. Different sodium oleate dosages affect the morphology of semi-hydrated calcium sulfate whiskers remarkably and there exists chemisorption between sodium oleate and semi-hydrated calcium sulfate whiskers.
