利用北京同步辐射小角x光散射实验站 ,对超临界流体的抗溶剂过程中 ,高分子的构象变化进行了初步的研究。实验表明 ,在不断加入抗溶剂的过程中 ,高分子链发生了以伸展规线团卷曲到蜷缩球体的转变。
Using the Beijing Synchrotron Radiation Small Angle X-ray Scattering Station, the conformational changes of the polymers during the anti-solvent of the supercritical fluid were studied. Experiments show that, in the continuous addition of anti-solvent process, the polymer chain occurred to extend the regulation of the curling of croutons to curl the transformation of the sphere.
