The seemingly simple notion of the hydrophobic effect can be viewed from multiple angles involving theory, simulation, and experiments. This viewpoint examines five attributes of predictive models to enhance synthetic efforts as well as experimental methods to quantify hydrophobicity. In addition, we compare existing predictive models against experimental data for polymer surface tension, lower critical solution temperature, solution self-assembly morphology, and degradation behavior. Key conclusions suggest that both the Hildebrand solubility parameters (HSPs) and surface area-normalized Log P (Log P SA–1) values provide unique and complementary insights into polymer phenomena. In particular, HSPs appear to better describe bulk polymer phenomena for thermoplastics such as surface tension, while Log P SA–1 values are well-suited for describing and predicting the behavior of polymers in solution.

高分子科学观点一百周年:疏水性在聚合物现象中的作用

疏水效应看似简单的概念可以从涉及理论,模拟和实验的多个角度来看。该观点检查了预测模型的五个属性,以增强合成效果,以及量化疏水性的实验方法。此外,我们将现有的预测模型与聚合物表面张力,较低临界溶液温度,溶液自组装形态和降解行为的实验数据进行了比较。主要结论表明,希尔德布兰德溶解度参数(HSPs)和表面积归一化Log P(Log P SA –1)值提供了对聚合物现象的独特且互补的见解。特别是,HSP似乎可以更好地描述热塑性塑料的本体聚合物现象,例如表面张力,而Log P SA –1值非常适合描述和预测溶液中聚合物的行为。
