该催化剂同时含有双脲基和季铵盐基团以及疏水基的长氟链。
And the length and branching of alkyl chain in the hydrophobic group are main structure factors affecting surfactants' efficiency and effectiveness.
而表面活性剂亲油基的碳链长度和亲油基的支化是影响效率和效能的主要结构因素。
The hydrophobic property of the resin has remarkably improved by adding the hydrophobic group of benzene ring to the molecular structure of the resin.
在分子结构上引入憎水基-苯环后,显著提高了脲醛树脂的耐水性。
It was found that polymer with higher hydrophobic group content had stronger recovery after deformation in three kinds of polymers with the same shear viscosity.
实验发现在相同剪切粘度下的三种聚合物,形变恢复能力随着疏水基含量的增大而增大。
The influences of hydrophobic group content on the stability of the silica sols and the surface wettability and vapour stability of the silica membranes were investigated.

疏水基团(hydrophobic group)是指分子中排斥或难以与水分子相互作用的部分。它们通常是非极性的,缺乏与水形成氢键的能力,倾向于聚集在一起或与非极性环境结合,从而尽可能减少与水接触的表面积。

疏水性本质:
在分子中的作用:
典型例子:
疏水基团是分子中非极性的、排斥水的部分,其行为主要由疏水效应驱动。它们在决定分子溶解性、生物大分子结构(如膜、蛋白质)以及各种自组装和分子识别过程中起着基础性作用。
