摘要
The order parameter and interfacial tension of a colloid-polymer system consisting of grafted silica particles in cyclohexane in the presence of the soluble polymer polydimethylsiloxane are determined experimentally in the entire liquid-liquid coexistence region, from the liquid-solid boundary to the critical point. The renormalized critical exponents of the order parameter and interfacial tension are found to be, respectively, beta* = 0.371 +/- 0.026 and mu* = 1.30 +/- 0.08, and are discussed in the light of theoretical predictions.
