摘要：
We developed a method of surface modification to prevent adsorption of precipitations to wall of glass microchannels. Some kinds of acrylate monomer were polymerized from immobilized polymerization initiator on the channel surface in this method. Because polymer chain was chemically bonded to silane group on the channel surface, the modified polymer layer had high durability to acid Or base. Effectiveness of the modification was demonstrated in adsorption prevention of iron(III) hydroxide provided in the modified microchannel while iron(III) hydroxide immediately adsorbed to a non-modified microchannel.
