Jinke Wang, Hao Yang, Lingwei Ma, Chenhao Ren & Dawei Zhang, University of Science and Technology Beijing, discuss how an active protective epoxy coating with weathering resistant, corrosion-warning and self-healing properties was developed by incorporating tannic acid (TA) loaded mesoporous silica (MSN-TA) nanocontainers. The introduction of MSN-TA nanocontainers could alleviate the coating degradation via scavenging … Continue reading Focus on smart coatings: Using bio-based tannic acid to achieve weathering and corrosion resistant, self-warning and self-healing epoxy coatings
