【摘要】 采用统计物理学方法,在Flory-Huggins高分子溶液理论中引入Gibbs分布,从而合理描述了高分子内聚能的温度依赖性.将此理论应用于求解高分子的溶度参数.采用此方法得到的溶度参数比以往的理论更加接近实验结果.这表明所推导的聚合物溶液热力学理论是合理的,可以更精确地求解高分子的溶度参数.更多还原

【Abstract】 Recently,our group introduced Gibbs distribution into Flory—Huggins polymer solution theory.It reasonably describes the polymer cohesion energy.In the present study,we applied the said theory to calculate the polymer solubility parameter and a more accurate value has been found.It indicates that the present theory is reliable and can be used to compute polymer solution parameters.更多还原
