动态光散射法研究海藻酸钠凝胶松弛行为
DYNAMIC LIGHT SCATTERING INVESTIGATION OF RELAXATION BEHAVIOR OF GEL IN ALGINATE AQUEOUS SYSTEM
【摘要】 在前文的基础上,用相关函数轮廓分析的方法剖析了运动模式的复杂性。通过海藻酸钠水溶液在0.1mol\LCaCl2水溶液透析凝胶化过程中交联网络的松弛时间谱表明它不是单一的峰,有两个特征运动模式,并随透析向更慢的运动模式发展,这很慢的运动模式估计与区域结构的生成有关。
【Abstract】 Based the previous paper, the complex motion models of AG aqueous during gelation were analysed having the aid of correlation function profile analysis for dispersive system. The spectrum of relaxation time during the gelation by dialysing of the AG aqueous (1 mg/mL) in 0.1 mol/L CaCl2 aqueous indicated the presence of two motion models becuase of double peaks at the plot of G(τc) vs τc in stead of a single peak. And furthermore, these motions shifted to the slower and slower direchin following the dialysing. The domain structures perhaps are responsible for these slow motion models.
