Imparting pH and temperature dual-responsiveness in a micellar solution of cationic surfactants by introducing a hydrotrope

Abstract

Over the recent years, intelligent, multi-responsive micelles have received considerable attention due to their promising application in a variety of fields, including biomedical technology, drug delivery, separation, and catalysis. However,...

Rheology on novel viscoelastic trimeric octadecyl zwitterionic surfactant micelle solutions

“…The organic salt counterion not only neutralizes surfactant hydrophilic headgroup charges but its hydrophobic carbon chains can be inserted into micelles, increasing hydrophobic chain effective volume and promoting wormlike micelle formation (Dreiss, 2007). However, it has been documented that adjusting external environmental parameters allows for simpler and faster construction of wormlike micelle solutions (Guo et al, 2019; Lv et al, 2022; Zhai et al, 2020). Especially for some zwitterionic surfactants (betaine and amine oxide), no additional additives are needed for them to induce the formation of wormlike micelles by simply changing the pH, temperature and concentration (Kumar et al, 2007; Zhang et al, 2015).…”
