“…21,22 In the previous study, we used silane to induce the deposition of DCPD coating on the Mg alloy. 12 The results proved its certain protection to the Mg alloy and the excellent biocompatibility of the composite coating. With the aim of further increasing the corrosion resistance of the composite coating, stearic acid and sodium stearate were used for posttreatment of the composite coating.…”

“…In addition to the pretreatment method and the composition of the solution, the deposition process can also be adjusted by pH, temperature, and so on . The as-prepared coatings mainly contain hydroxyapatite, anhydrous calcium phosphate, dicalcium phosphate dihydrate (DCPD), and so on. They have been proven to be osteoconductive, and hence biomimetic deposition is investigated for the preparation of biocompatible coatings …”

Magnesium (Mg) alloys, a degradable material, have been studied for medical applications due to their excellent mechanical and chemical properties. However, their applications are limited by rapid corrosion. In this work, stearic acid and sodium stearate were used to treat the silane-induced calcium phosphate dihydrate coating to improve its protection for the Mg alloy further without changing the bone-like structure of calcium phosphate. The different effects of stearic acid treatment and sodium stearate treatment were compared. Electrochemical test and immersion test results confirmed that the corrosion resistance of the stearic acid-treated composite coating was greatly enhanced with a reduced corrosion current density by 3 orders of magnitude and hydrogen evolution reduced to 1/25 after 14 days. The stearic acid-treated coating also exhibited improved in vitro biocompatibility corroborated by promoted cell viability and better cell morphology.

“…There are two main methods to fabricate polymer coatings on Mg alloys, namely dip coating and spin coating [ 65 ]. Wang et al [ 66 ] reported that silane-coupling agent calcium hydrogen phosphate dihydrate (SCA/DCPD) coating prepared by dip-coating method resulted in AZ60 alloy with improved corrosion resistance, whereas silane-coupling agent calcium carbonate (SCA/CaCO 3 ) coating prepared by biomimetic deposition method resulted in AZ60 alloy with improved biocompatibility. Al-Sherify et al [ 67 ] reported that polymethyl methacrylate/hydroxyapatite (PMMA/HA) composite coating on AZ31 alloy prepared by spin-coating method effectively improved the corrosion resistance in Ringer’s solution.…”

Percolative composites with high permittivity and low loss have drawn enormous attention in the research community, exhibiting wide range of applications in sensors, capacitors, field-effect transistors, antennas, etc. In this work, flexible and biocompatible polystyrene/multi-walled carbon nanotubes (PS/MWCNTs) films with high permittivity and low loss near percolation threshold were achieved by solution mixing assisted with non-solvent induced phase separation (NIPS) strategy and followed by the hot press method. Cytotoxicity experiments proved that the experimental process and products are green, environmentally friendly and biocompatible. The microstructure and dielectric properties were investigated. When MWCNTs content reached 15 wt%, high permittivity and low loss were simultaneously realized. Combining the flexibility and non-toxicity, the PS/MWCNTs films with high permittivity and low loss exhibit great potentials in wearable devices, skin sensors and flexible electronics.
