基于聚乙二醇的剪切增稠软体膜的制备与表征

Preparation and Properties of Shear Thickening films Base on the Polyethylene Glycol

  • 摘要: 研究了纳米二氧化硅-聚乙二醇剪切增稠软体膜(STF)的制备过程与性能表征。以乙醇和丙酮为稀释剂,以气相法生产的纳米二氧化硅和聚乙二醇为原材料,混合使用机械搅拌器和超声波清洗器制备出了不同质量分数的剪切增稠软体膜。通过红外光谱表征、流变性能测试,研究了剪切增稠软体膜的形成特征、不同状态下剪切增稠软体膜的变化、不同质量分数的剪切增稠软体膜的变化特征以及纳米二氧化硅质量分数对剪切增稠的影响。结果显示:剪切增稠分散体系的形成有新的化学键的形成,但是剪切增稠现象是一种物理现象,没有发生化学反应。剪切增稠分为的4个阶段,即:剪切不稳定、剪切变稀、剪切增稠、再次剪切变稀阶段,并且质量分数越大,剪切增稠效果越明显。

     

    Abstract: The report investigates the preparation and characterization of nanosilica-polyethylene glycol shear thickening films (STF). Using ethanol and acetone as diluent, nano-silica and polyethylene glycol produced by gas-phase method were used as raw materials. Different concentrations of shear-thickening fluids were prepared by mixing with mechanical stirrer and ultrasonic cleaner. The characteristics of shear thickening fluid, the change of shear thickening fluid under different conditions, the change characteristics of shear thickening fluid with different mass fractions, and the properties of nano-silica effect of mass fraction on shearing thickening. The results show that the formation of shear thickening dispersion system with the formation of a new chemical bond, but the shear thickening phenomenon is a physical phenomenon, no chemical reaction. Shear thickening is divided into four stages, namely:shear instability, shear thinning, shear thickening, again shear thinning stage, and the greater the mass fraction, the more obvious the effect of shear thickening.
