| Abstract | ||||
| White Sand\TiO2 core-shell multifunctional pigments have been synthesized successfully by simple chemical method. Economical white sand is used as a coating pigment for the first time in this work. The prepared pigments were investigated physicochemically by many techniques. Then they were applied in paper coating mixtures and their influence on coated paper properties were systematically investigated. SEM and EDAX investigations proved that the TiO2 shell of the prepared pigments is thin and it was in the range of 30-50% of the whole core-shell structure. The application of the prepared pigments in coating mixture increased brightness, opacity, burst strength, burst index, tensile strength, tensile energy absorption, print density and smoothness of the coated papers. The magnificent effect has been obtained upon increasing the percent of TiO2 shell in white sand\TiO2 core-shell. Air permeance started to decrease then increased with increasing the percent of TiO2 shell | ||||
