MAGNETIC PHOTOCURABLE RESIN AND THREE-DIMENSIONAL MAGNETIC STRUCTURE MADE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a photocurable resin with magnetic microparticles dispersed homogeneously by incorporating the magnetic microparticles into a photocurable resin and simultaneously adding a thickening agent to the resin to prevent both the aggregation and precipitation of the magnetic microparticles followed by agitation. SOLUTION: The photocurable resin is obtained by adding magnetic microparticles and a thickening agent to a photocurable resin followed by agitation. Thus, such magnetic microparticles whose aggregation is inevitable in the case of conventional techniques can be homogeneously dispersed in the resin. A complicated three-dimensional magnetic structure impossible to be achieved by conventional techniques can be made by curing and laminating the thus obtained magnetic photocurable resin by a photoforming method. The method enables new magnetically driven actuators and sensors to be attained. These accomplishments may be served as an innovative technology in various sectors including microdevice and medical ones currently under rapid growth. COPYRIGHT: (C)2010,JPO&INPIT
