Preparation and properties of tung oil-calcium alginate self-healing coating
摘要
Abstract
Stainless steel is widely used in implant materials and medical devices,but it is susceptible to corrosion in the human body environment,which can lead to device failure.To address this problem,a self-healing coating was designed.Core-shell microcapsules of tung oil-calcium alginate with medical tung oil as the core and calcium alginate as the shell material were prepared by in situ emulsion polymerization,and then the microcapsules were dispersed in modified silicone gel to form a wear-resistant and corrosion-resistant coating.The microcapsules were characterized by scanning electron microscope,Fourier transform infrared spectrometer and thermogravimetric analyzer.The results show that when the mass fraction of microcapsule in the coating is 15%,the wear resistance is optimal,the friction coefficient is as low as 0.32,and the wear depth is only 0.35 mm.After being immersed in the simulated body fluid for 20 d,the low-frequency impedance was 7.0×105 Ω·cm2,which demonstrated that tung oil as the core has a self-healing effect on microcracks.关键词
