Effect of chain length and counter-ion on interaction study of mixed micellar system of isoquinoline-based surface active ionic liquid and cationic surfactants in aqueous medium

Scrutinizing Self-Assembly, Surface Activity and Aggregation Behavior of Mixtures of Imidazolium Based Ionic Liquids and Surfactants: A Comprehensive Review

“…Dynamic light scattering (DLS) can be employed to determine the size of micelles formed (Mata et al, 2004 ; Rai et al, 2010 ; Bhatt et al, 2014 ; Singh and Kang, 2015 ; Panda et al, 2018 ). Other techniques such as proton nuclear magnetic resonance ( 1 H-NMR) spectroscopy, scanning electron microscopy (SEM) as well as tunneling electron microscopy (TEM) can also be employed to investigate the aggregation behavior of surface-active molecules (Inoue and Yamakawa, 2011 ; Mahajan et al, 2012 ; Bharmoria et al, 2013 ; Chabba et al, 2015 ; Pal and Punia, 2019a ).…”

“…If the values of cmc * of mixed systems come out to be different than experimental cmc of that system, it signifies some sort of interactions is occurring within the mixed system. The less value of cmc * as compared to experimental cmc (cmc * < cmc) indicates positive deviation (antagonism) while the more value of cmc * as compared to experimental cmc (cmc * > cmc) indicates negative deviation (synergism) in the mixed system (Clint, 1975;Motomura et al, 1984;Rodenas et al, 1999;Kabirud et al, 2010;Kumar and Rub, 2017;Azum et al, 2018;Das et al, 2018;Hoque et al, 2018;Kumar et al, 2018a;Pal and Punia, 2019a). Rubingh model can be further utilized to determine the micellar mole fraction X Rub 1 and interaction parameter (β) by using the following equations ( 17) and ( 18).…”

“…The values of activity coefficients can be used to calculate the excess free energy of mixed micellization G a ex by using the following equation ( 28). (Clint, 1975;Motomura et al, 1984;Rodenas et al, 1999;Kabir-ud et al, 2010;Kumar and Rub, 2017;Azum et al, 2018;Das et al, 2018;Hoque et al, 2018;Kumar et al, 2018a;Pal and Punia, 2019a).…”

“…This leads to the determination of mixed micellar parameters which further can be utilized to know about the interactions prevailing in the mixed systems. Various theoretical models such as Clint, Rubingh, Motomura, and Rodenas are utilized by various researchers to evaluate mixed micellar parameters as well as ideal or non-ideal nature of mixing (Clint, 1975 ; Rodenas et al, 1999 ; Kabir-ud et al, 2010 ; Kumar and Rub, 2017 ; Azum et al, 2018 ; Das et al, 2018 ; Hoque et al, 2018 ; Kumar et al, 2018a ; Pal and Punia, 2019a ). In the case of mixed surfactant systems, the determination of the molar fraction of each surfactant in the aggregate iss difficult, which is needed to interpret the behavior of surfactant mixtures by using Clint relation as well as regular solution theory (RST).…”

“…However, the conventional surfactants are also very important, having immense applications in a variety of fields, such as in emulsifying agents, in the paint and cosmetic industries, and in nanoreactors for enzymatic reactions (Lépori et al, 2019; Morsy, 2014; Razipour et al, 2020; Sagir et al, 2020). Mixing the conventional surfactants with SAIL has been known to have a remarkable effect on the properties of conventional surfactants (Pal and Punia, 2019a; Qin and Wang, 2017). These properties can be significantly altered by the use of SAIL as an additive.…”
