Implant Corrosion Protection
In article number 2106056, Yufeng Zheng, Pan Xiong, Yunsong Liu, Yongsheng Zhou, and co‐workers construct a pH stimuli‐responsive silk‐based halloysite nanotube/phytic acid self‐healing coating to slow down the corrosion rate of Mg‐1Ca alloy. The coating exhibits appealing active corrosion protection, superior biocompatibility and osteogenic ability.
Mg‐Ca alloys have emerged as a promising research direction for biomedical implants in the orthopedic field. However, their clinical use is deterred by their fast corrosion rate. In this work, a pH stimuli‐responsive silk‐halloysite (HNT)/phytic acid (PA) self‐healing coating (Silk‐HNT/PA) is constructed to slow down the corrosion rate of Mg‐1Ca alloy and its cell viability and osteogenic differentiation...
