Title:
POLISHING NANOFIBER AGGREGATE AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2019/106774
Kind Code:
A1
Abstract:
Provided are: a polishing nanofiber aggregate capable of suppressing a reduction in polishing efficiency even when fine abrasive powder is used; and a method for producing the same. A polishing nanofiber aggregate (1) can be used by adsorbing thereon a slurry having fine abrasive powder mixed in a liquid. The polishing nanofiber aggregate (1) has an average fiber diameter (d) of 400-1000 nm, and a porosity (η) of 0.70-0.95. In the polishing nanofiber aggregate (1), the distance (e1) between fibers can be reduced without compromising porosity (η). As a result, it is possible to inhibit abrasive grains having a small particle size from entering the spaces between the fibers.
