About this Research Topic
Solid product coating is beneficial in various instances, such as coating of particles and powders to improve their flowability, or coating of tablets to protect them from damage or to control the release rate of active ingredients. Coating is traditionally carried out using liquids, though there is a drive to move towards dry powder coating where possible, in order to prevent the use of volatile organic solvents, to lower operational costs and to enable coating of moisture sensitive components. However, dry powder coating is less well understood and can be wasteful in terms of material use and energy input.
The goal of this Research Topic is to create a framework for enabling manufacturers of coated solid products to better design and control these dry powder coating processes. Powders used for coating are typically fine and cohesive, and hence need to be separated and directed to the host surface. To enable dry powder coating approaches to be more widely adopted, it is necessary to understand how particles mix, deaggregate and attach to host surfaces. Coating powders and the host surfaces are often multi-component, so understanding how to account for the distribution of properties and interactions in the mixture is critical too.
We welcome the submission of Original Research, Review, Mini Review, Perspective articles on experimental, computational and theoretical advances aiding the development of a more robust mechanism for controlling dry powder coating processes. The areas of focus may include, but are not limited to:
• Powder mixing and segregation
• Agglomeration and deagglomeration
• Dry powder coating
• Particles and solids coating
• Phenomena that are relevant to dry powder coating processes
• Mixer design and control.
