A particulate cellulose derivative is obtained in a process of grinding and drying a moist cellulose derivative which comprises the steps of A) providing a cellulose derivative having a moisture content of from 60 to 95 percent, based on the total weight of the moist cellulose derivative, B) grinding and partially drying the moist cellulose derivative in a gas-swept impact mill; C) contacting the ground and partially dried cellulose derivative with an additional amount of a drying gas outside the gas-swept impact mill; and D) subjecting the cellulose derivative to partial depolymerization after having contacted the cellulose derivative with a drying gas in step C). The obtained particulate cellulose derivative has a high untapped bulk density, a good flowability and a low color intensity.

Optically transparent films can comprise a coating of nanodiamonds to introduce desirable properties, such as hardness, good thermal conductivity and an increased dielectric constant. In general, transparent conductive films can be formed with desirable property enhancing nanoparticles included in a transparent conductive layer and/or in a coating layer. Property enhancing nanoparticles can be formed from materials having a large hardness parameter, a large thermal conductivity and/or a large dielectric constant. Suitable polymers are incorporated as a binder in the layers with the property enhancing nanoparticles. The coatings with property enhancing nanoparticles can be solution coated and corresponding solutions are described.
