Comparison of Detection Methods of Pore Characteristic of Inkjet Paper Coating

Abstract:

nkjet paper coating is a porous coating getting from a mixture of pigments, adhesives and a small amount of additives by way of coating and drying. Coating structure is defined as the coating thickness, porosity, pore size and its distribution, the surface and internal distribution of coating components. In which, pore characteristic (such as porosity, pore shape, pore size and its distribution) play an important role in the decision of absorption and spreading of ink droplet on inkjet paper. The commonly used detection methods of coating microstructure include image analysis and various physical detection methods. This paper selected 4 inkjet papers, and the two image analysis methods (SEM and AFM) were used to measure the pore characteristic of the testing coating, and characteristics of the two methods were analyzed and compared. And AFM observation method is more suitable for testing pore characteristics of inkjet paper coating, as it could provide more information on the microscopic morphology and coating composition. In the study of the structure of the coating surface, SEM and AFM have their own strengths and complement each other.
