They found that the stearic acid within 1–2 wt% was an optimal content. Higher percentages might result in adverse effects in the thermal decomposition of hydromagnesite and the flame retardant effectiveness of EVA composite [14]. To achieve adequate flame resistance, the high loading of mineral fillers is often required in …
ing of powder particulates. In this study, a super-hydrophobic coating with a contact angle of 153 ± 2 was fabricated by ball milling a copper powder and stearic acid mixture onto an aluminum foil. Fourier-transform infrared spectroscopy demonstrated that stearic acid was successfully transferred to the surface
