Abstract

Effects of gas grafting treatment using palmitoyl chloride on properties of papers coated with three different types of CNFs whose crystalline structures are different were investigated. One type of cellulose I based CNF (cellulose nanofibril) and two types of cellulose II based CNFs were utilized for this study. Effects of the applied amount of palmitoyl chloride on the CNF coated papers were also investigated. It was found that tensile strength and stabilities of optical properties of the CNF coated papers such as color, brightness, and yellowness were deteriorated with the gas grafting treatment with palmitoyl chloride. Increasing the applied amount of palmitoyl chloride increased the degree of deterioration. Applying excess amount of palmitoyl chloride for gas grafting increased the roughness of the CNF coated paper. In addition, increasing the pick-up of CNF on paper increased air resistance while the applied amount of palmitoyl chloride did not show any significant effects on air permeability.
