早在古代人们就知道用高分子化合物来稳定胶体,例如中国的墨、古埃及壁画上的颜料都是用明胶、酪素来稳定的。可是其稳定性原理的确立,仅是本世纪五十年代以后的事。在三十年代初,Zsiymondy等人就利用“金数”、“红数”实验,企图用定量结果来说明高分子对胶体稳定的原理。因为概念上的错误,自然导致结 As early as ancient times, people knew that they used colloidal compounds to stabilize colloids, such as Chinese ink. The pigments in ancient Egyptian murals are all stabilized by gelatin and casein. However, the establishment of its stability principle is only something after the 1950s. In the early 1930s, Zsiymondy et al. Used “gold numbers” and “red numbers” experiments in an attempt to use quantitative results to illustrate the principle that polymers stabilize colloids. Because of the conceptual error, it naturally leads to knots
