Temperature effect on the viscoelastic properties of solutions of cylindrical mixed micelles of zwitterionic and anionic surfactants

Soft magnetic nanocomposites based on adaptive matrix of wormlike surfactant micelles

“…9 In addition to improved sedimentation stability, WLM solutions can provide some other advantages as a carrier for magnetic particles. First, being formed by weak non-covalent interactions the WLMs can be easily reorganized [23][24][25][26][27][28][29] and one can expect that they will not restrict the mobility of particles under the action of magnetic eld. Second, in oscillatory measurements, the neat WLM solutions demonstrate a linear viscoelastic region [30][31][32] in a wide range of strain and one can anticipate that it will remain in the presence of particles.…”

Injectable ultra-soft hydrogel with natural nanoclay

“…This surfactant can make transient network of long WLMs, as was shown recently [23,24]. Betaines demonstrate a strong synergism when mixed with anionic surfactant [25], in particular, sodium dodecyl sulfate (SDS) [26]. For this reason, in the present paper, a small amount of SDS is added to OB.…”

“…7(a), it is seen that the disruption of the network is faster than the recovery. Gradual growth of the storage modulus takes tens of the seconds that is close to the typical relaxation time for the WLM networks [20,25]. Such restoring rate is comparable to the restoring rate of various injectable systems for wound healing application [5].…”

Spontaneous surface adsorption of aqueous graphene oxide by synergy with surfactants

“…Zwitterionic surfactants are, to an extent, self-screening, which allows them to pack more densely at interfaces while also having high aqueous solubilities. [51][52][53][54][55] In the case of OAPB, it is likely that GO experiences attractive interactions with the positively charged ammonium in the head-group, especially in cases where the carboxyl group is protonated. OAPB molecules are thus going to have high affinities for the GO surfaces, and render the sheets hydrophobic.…”
