Abstract
Official abstract text for this publication.
The present invention aims to provide cellulose fibers covered by inorganic particles on the fiber surface. According to the present invention, complexes of a cellulose fiber and inorganic particles wherein 15% or more of the surface of the cellulose fiber is covered by the inorganic particles can be obtained.
First claim
Opening claim text (preview).
1 . A complex of a cellulose fiber and inorganic particles, wherein 15% or more of the surface of the cellulose fiber is covered by the inorganic particles. 2 . The complex of claim 1 , wherein the inorganic particles have an average primary particle size of 1 μm or less. 3 . The complex of claim 1 , wherein the inorganic particles have an average primary particle size of 200 nm or less. 4 . The complex of claim 1 , wherein the inorganic particles have an average primary particle size of 100 nm or less. 5 . The complex of claim 1 , wherein the weight ratio between the cellulose fiber and the inorganic particles is 5/95 to 95/5. 6 . The complex of claim 1 , wherein the inorganic particles are at least partially a metal salt of calcium, silicic acid, magnesium, barium or aluminum or metal particles containing titanium, copper or zinc. 7 . The complex of claim 1 , wherein the cellulose fiber is a wood-derived cellulose fiber. 8 . The complex of claim 1 , wherein the cellulose fiber is a wood-derived pulp fiber. 9 . The complex of claim 1 , wherein the cellulose fiber is a chemical pulp. 10 . The complex of claim 1 , wherein the cellulose fiber is a pulverized cellulose. 11 . The complex of claim 1 , wherein the inorganic particles are barium sulfate. 12 . A radiation shielding material comprising the complex of claim 11 . 13 . A process for preparing the complex of claim 1 , comprising synthesizing inorganic particles in a solution in the presence of a fiber.
