Abstract A method to measure Hansen solubility parameters for organophilic fluoromica is developed. For this purpose, fluoromica with four different intercalated molecules (surfactants) have been dispersed in various solvents. These surfactants change the fluoromica surface energies described by Hansen solubility parameters (HSP). The three Hansen solubility parameters (dispersion, polar and hydrogen bonding) of different organophilic fluoromicas have been obtained by using gravimetric analysis. The dispersion parameters for all four organophilic fluoromicas are almost identical, with a value around 17 MPa . Whereas polar and H-bonding parameters are varying with the used surfactants. Surprisingly the polar and hydrogen bonding values for hydrophobic alkyl chain tailored surfactants are higher than those for a hydrophilic surfactant with poly(ethylene glycol) chains. The determined HSP values allow calculating the dispersibility of the organophilic fluoromica in solvents via the Flory-Huggins (F-H) parameter. These F-H parameters describes the effective difference in HSP related surface energies of particles and solvent molecules and are used to identify potential solvents for an exfoliation process. With this approach, beside known solvents such as chloroform, also new potential candidates such as trichloroethylene, and benzyl ethyl ether are identified for dispersing/exfoliating modified organophilic fluoromica. This work is accompanied by X-ray diffraction (XRD) measurements to gain knowledge about the interlayer space of the different organophilic fluoromicas.

测量亲有机性氟云母的 Hansen 溶解度参数和评估用于剥离的潜在溶剂

摘要 开发了一种测量亲有机氟云母的汉森溶解度参数的方法。为此，具有四种不同嵌入分子（表面活性剂）的氟云母已分散在各种溶剂中。这些表面活性剂改变了由汉森溶解度参数 (HSP) 描述的氟云母表面能。不同亲有机氟云母的三个汉森溶解度参数（分散、极性和氢键）已通过重量分析获得。所有四种亲有机氟云母的分散参数几乎相同，值约为 17 MPa。而极性和氢键参数随使用的表面活性剂而变化。令人惊讶的是，疏水性烷基链定制表面活性剂的极性和氢键值高于具有聚（乙二醇）链的亲水性表面活性剂的极性和氢键值。确定的 HSP 值允许通过 Flory-Huggins (FH) 参数计算亲有机氟云母在溶剂中的分散性。这些 FH 参数描述了粒子和溶剂分子的 HSP 相关表面能的有效差异，并用于识别剥落过程的潜在溶剂。通过这种方法，除了已知的溶剂（如氯仿）外，还确定了新的潜在候选物，如三氯乙烯和苄基乙醚，用于分散/剥离改性的亲有机氟云母。
