/ Inorganic-organic hybrid particles for absorbing simultaneously hydrophobic and hydrophillic pollutants from water

摘要

The present invention relates to an alkoxysilane functionalized amphipathic precursor having hyperbranched cross-linking between alkoxysilane functionalized precursors having a structure of the following formula (1), wherein a part of the alkoxysilane functional group of the amphipathic precursor is chemically bonded to silica particles or metal oxide nanoparticles Organic hybrid particles for removing pollutants. [Chemical Formula 1] (In the formula 1, Wherein A is a substance comprising a hydrophilic segment and two or more hydroxyl groups (-OH), wherein an isocyanate group (-CN) of the B and a urethane bond (-OCONH-) are formed; Wherein B is a substance comprising a hydrophobic segment and two or more isocyanate groups (-CN), one isocyanate group reacts with the hydroxy group of A to form a urethane bond, and the other is a hydroxyl group or amine React with the group to form a urethane bond or a urea (-NHCONH-) bond; Wherein C is a substance comprising a hydroxyl group and an alkoxysilane group, or an amine group and an alkoxysilane group, wherein a hydroxyl group or an amine group reacts with the isocyanate group of B to form a urethane bond or a urea bond; n is an integer of 1 or more.)
