PROBLEM TO BE SOLVED: To provide a resin composite in which lipophilic alumina nanofibers having a high aspect ratio are dispersed.SOLUTION: An alumina sol in which lipophilic alumina nanofibers are uniformly dispersed can be provided by coating the surface of alumina nanofibers prepared by a sol-gel method and having an aspect ratio (major axis/minor axis) within the range of 70-5,000 with one compound selected from a phosphoric acid compound, a sulfonic acid compound, and an organic acid. Further, the resin composite in which the lipophilic alumina nanofibers are dispersed while maintaining a high aspect ratio and fiber length can be provided by using the alumina sol.SELECTED DRAWING: None |
