In this work, the stability and transformation of two kinds of TiC with different stoichiometries in Cu–Si melts are studied, respectively. It is found that the near-stoichiometirc TiC with fewer carbon vacancies (designated as TiCx), such as TiC0.9, is relatively stable in Cu–Si melts, while the non-stoichiometric TiC with more carbon vacancies (designated as TiCy), such as TiC0.6, is unstable. And...
Percolative dielectric composites of sulfonated poly(aryl ether ketone) (SPAEK) and acidified graphite nanosheets (AGSs) were fabricated by a solution method. The dielectric constant of the as‐prepared composite with 4.01 vol % AGSs was found to be 330 at 1000 Hz; this was a significant increase compared to that of pure SPAEK. Through the calculation, a low percolation threshold of the AGS/SPAEK composite...
