dc.description.abstract | We investigated the effect of polymers on the cracking of particulate coating layers. Carboxymethyl cellulose (CMC) and polyvinyl alcohol (PVA) were used as contrasting polymer additives due to their different surface charges and film characteristics. Drying stress that generates cracking in particulate layers increased with the addition of both polymers. However, there was a large difference in the critical cracking thickness (CCT) depending on the two polymers, indicating that the structural and mechanical properties of particulate layers varied with the nature of polymer additive. A strong positive correlation was observed between the toughness and CCT of the particulate layer. Compared with particulate layers containing CMC, those containing PVA exhibited 77.8% higher CCT because denser and tougher layers were formed when PVA was added to the coating suspension. Our findings clearly demonstrate that cracking of coating layer can be prevented by improving the toughness of the layer. | - |
