1.Complex Theological behavior of CNF suspensions is used to help process them into uniform coating layers 2.The coating apparatus fluidizes the material and thereby enables application of thick and uniform CNF coatings 3.Addition of CMC was found useful for improving the coatability of CNF suspensions by way of improving the water retention and modifying the low shear rheology 4.CNF coating improves the strength properties to some extent even at very low coat weights 5.The improvement in barrier properties of CNF coated paperboards with increasing coating thickness was substantial 6.CNF-coated paperboards demonstrated excellent barrier against air, heptane vapor, grease and mineral oil 7.WVTR also improved significantly with the CNF coating
