Polypropylene melt-blown fabric as the core filter materials plays an important role in manufacturing civil and medical epidemic prevention products. The aim of this study was to optimize control particle filtration efficiency apparent surface quality from perspectives electret masterbatch composition processing parameters. Magnesium stearate fumed silica were used manufacture polypropylene fab...

Since solid-state heat transport in a highly porous nanocomposite strongly depends on the thermal boundary conductance (TBC) between constituent nanomaterials, further suppression of TBC is important for improving performance insulators. Here, targeting fabricated by stamping fumed silica nanoparticles, we perform wide variety surface functionalization nanoparticles silane coupling method and i...

This study evaluated the effect of structural color phenomenon in resin composites (RCs) on adjustment restorations by investgating their reproduction performance human incisors various shade. Cervical cavities were filled with a single-shade RC 260 nm spherical fillers (Omnichroma (OMN)), conventional A2-shade RCs (Estelite Σ Quick or Clearfil AP-X), experimental 5–50 fumed silica (R1) and 100...

In this study the leaching of a one component (1K) structural epoxy model adhesive for automotive industry is analysed via fourier transform infrared spectroscopy (FT-IR). addition, gravimetric water uptake and morphological changes were observed. Findings indicate two-stage absorption at room temperature, whereas 70 °C shows drastically increased value including loss mass after 500 h immersion...
