摘要
Gemini表面活性剂是当前倍受关注的两亲分子,由于其在许多领域有着广泛的应用前景,而临界胶束浓度(CMC)和动态表面张力(DST)又是衡量表面活性剂性能优越与否的两个重要参数,因而对其热力学和动力学性质的进一步研究显得尤为重要。
     本文采用最大泡压法(MBP),对十种新型Gemini表面活性剂在303.15K、四个浓度(5.64mmol/L、8.46mmol/L、11.28mmol/L、16.92mmol/L)下的DST曲线进行了测定,对其动态吸附机理进行了研究。结果表明,浓度越大,γ(t)从γ0开始下降的速率越大;吸附初期为扩散控制吸附,吸附中期为混合动力控制吸附,吸附末期为拟扩散控制吸附。
     采用电导率法,测定了两种X型Gemini表面活性剂在三个温度(298.15K、303.15K和308.15K)、三种比例(5%、10%和15%)(V/V)下的四种有机溶剂(甲醇、乙醇、乙二醇和1,4-二氧六环)/水溶液中的电导率,并求得了各自的临界胶束浓度、胶束离子化程度α。计算了胶束生成的各种热力学参数(?)上述参数的物理意义及变化规律。研究表明,这两种表面活性剂在各自体系下胶束的生成均为熵驱动过程,有机溶剂的加入使得其胶束更加难于生成,对应的CMC值有较大的提高,影响程度大小的顺序为:1,4-二氧六环>甲醇>乙二醇>乙醇。
Gemini surfactant is amphiphilic molecules of receiving widespread attention byresearchers that has wide application prospects in many fields, the critical micelleconcentration (CMC) and the dynamic surface tension (DST) are two important parameters ofthe superior performance of surfactant, thus further study of its thermodynamic and kineticproperties is particularly important.
     In this paper, the DST curves of ten kinds of novel Gemini surfactants were measuredby the maximum bubble pressure method(MBP) at 303.15K, at four concentration (5.64mmol/L, 8.46mmol/L, 11.28mmol/L, 16.92mmol/L), and the dynamic adsorption mechanism werestudied. The results show that the rate of thatγ(t) down fromγ0of the higher concentration isgreater; the adsorption process is controlled by diffusion at the start, the adsorption process ofthe mid is hybrid control adsorption and the adsorption process of the late is controlled bysimulant diffusion.
     Conductivities of the two X-type Gemini surfactants were measured at threetemperatures (298.15K, 303.15K and 308.15K), and at three ratios (5%, 10% and 15%) (V/V)of four organic solvents (methanol, ethanol, ethylene glycol and 1,4-dioxane)/water, and theirrespective critical micelle concentration and degree of micelle ionizationαwere obtained. Thevarious thermodynamic parameters (?) were calculatedby the CMC, and the physical meaning of these parameters and variation were studied. Theresults show that the micelle formation of these surfactants in their systems are driven byentropy, the formation of micelle is more difficult due to the organic solvent addition and thecorresponding CMC is greatly improved, and the impact sequence is 1,4-dioxane > methanol> ethylene glycol > ethanol.
