Preparation of novel functional Mg/O/PCL/ZnO composite biomaterials and their corrosion resistance

Preparation of Degradable Superhydrophobic Mg/P/Z/F/H Composite Materials and Their Anticorrosion

“…In the Nyquist plane the impedance value of the working electrode is represented by the diameter of the capacitive loop. [25] As shown in Fig 5, Mg/P/Z/F/H samples showed the best anticorrosion performance The value of Rct for the Mg/P/Z/F/H samples (>1.5×10 7 Ωcm 2 ) is about 2×10 4 times larger than that of the Bare samples (750Ωcm 2 ). EIS results of Mg/P/Z/F/H samples indicated that after heating process the superhydrophobic samples Mg/P/Z/F/H samples could have desirable anti-corrosion performance.…”

“…As one of the lightest metal, with a density two-thirds that of aluminium and one-quarter that of steel, magnesium alloys thus have the great potential to improve system performance and energy efficiency in aerospace, auto industry, shipbuilding, mobile electronics, and bioengineering applications because of the magnesium's excellent chemical, mechanical, biological and physical properties. [23][24][25][26][27] However, because of magnesium's poor corrosion resistance especially in the corrosive medium environment of Cl -, the magnesium alloys' applications are limited. [27][28][29][30][31] Furthermore, containing rare heavy metal elements such as Cu, Ni and Pb, the magnesium alloys are environment friendly and used as the biodegradable metals.…”

“…[27][28][29][30][31] Furthermore, containing rare heavy metal elements such as Cu, Ni and Pb, the magnesium alloys are environment friendly and used as the biodegradable metals. [25] As a typical aliphatic polyesters, poly (ε-caprolactone) (PCL) is nontoxic and ecofriendly to living organisms which is widely used in food packaging and pharmaceutical industry. [25,[32][33][34][35][36] ZnO powders are used in electronic and optoelectronic devices, solar cells and pharmaceuti-cal engineering because of the high safety, low price, extraodinary opto-electronic property and lacking of polluting effects as a newer type of promising candidate.…”

[35,37,38] In this study, degradable and superhydrophobic M/P/Z/F/H composite materials were prepared through one-step method to solve the poor corrosion resistance of magnesium.…”
