Popis: Halloysite is modified with 3-aminopropyltriethoxysilane in various solvents without pretreatment. According to elemental analysis, FTIR spectroscopy, and thermogravimetry, the reaction between 3‑aminopropyltriethoxysilane and halloysite successfully proceeds regardless of the nature of the solvent. The maximum degree of functionalization of interaction products is achieved at the equimolar silane : halloysite ratio; as this value is increased, the degree of functionalization decreases. The magnitude of the degree of hydrolysis changes symbatically with the degree of functionalization.
