  • 摘要:Abstract This study is focused on novel anti-corrosive support. This coating is based on the mixed matrix ( MM ) including epoxy and its hardener as thermoset polymer, melamine–formaldehyde as the organic phase, activated graphite as both inorganic and conductive phases, as well as wollastonite nanoparticles as filler. The wollastonite nanoparticles are synthesized by the new and novel method as suitable etching using hydrofluoric acid, “ HF ” at room temperature (25 ℃). The synthesized wollastonite nanoparticles are then adapted as a suitable filler during the formation of a new type of MM anti-corrosive coating for the preservation of metals form any corrosion. According to the results, during coating the MM, significant positive characteristics such as enough positive open circuit potential ( OCP ), small enough ( i corr ), low cost, significant chemical/mechanical stability and acceptable flexibility are observed. Based on to the weight-loss analysis test on the MM-modified stainless steel during a 42-day time interval, the corrosion rate % is decreased from 74.86 to 0.34. In addition, the electrochemical impedance spectroscopy reveals major enhancements in the double-layer resistance and solution resistance of the cell system. Based on the electrochemical measurements, noticeable reduction and enhancement are observed in the correction rate and potential, respectively, during introducing hard corrosive conditions such as NaCl (3.0%, w/v) and HCl (1.0 mol L −1 ) environments that reveal the acceptable anti-corrosive behavior of the synthesized MM. The introduced MM is therefore considered as low cost, safe, eco-friendly, industrial-justified anti-corrosion support.
