The rheological character of a polymer often appears as shear-thinning. Most polymers behaviour in a solution can be explained by the polymer chain or hard sphere theory. Other than that, shear-thickening polymer solution also exists. Its behavior can be explained by dilatant theory, which suggests that the shear-thickening of the solution is due to the swelling of the polymer particles. This phenomenon often occurs in suspension or emulsion. Solution exhibits a mixed behavior can also be found whose behavior is such that shear-thinning occurs under low shear force and shear-thickening occurs under high shear force. Under this circumstance, the viscosity versus shear force graph exhibits a spoon shaped curve. The rheological study can be applied to the dispersion of paint which can predict the dispersion effect of various polymer materials in solution.
中文摘要一般高分子聚合物溶液的流变行为多半呈现剪稀(shear-thinning)的现象,而大部分的高分子在溶液中的行为是以分子链或是硬球观点来解释,另外也有剪稠(shear-thickening)现象的高分子溶液,其流变行为则是以膨胀体观点来解释,即在高剪切力下,由於高分子团体积变大而使溶液黏度升高,这在悬伏液、乳液等常见;但也有在低剪切力下,溶液具有剪稀的行为,而在高剪切力下却成现剪稠的行为,在黏度对剪切力作图时,会呈现出一个勾形曲线的图形;流变行为的探讨可应用在涂布材料的分散技术上,以推测不同的高分子溶液对分散效果的影响。
