Surfactant dispersion

As indicated by Puig et al. (35). surfactant retention and attendant pressure buildup in the rock can be greatly reduced if the surfactant dispersion is converted into the liquid crystalline state. Unilameller vesicles are preferred in the field work rather than the multilamellar... [Pg.401]

CNT-coated electrodes can be constructed easily as long as stable CNT suspensions are obtained. However, one needs to choose a suitable surfactant dispersant for the fabrication of CNT/surfactant-modihed electrodes with high catalytic and good selectivity toward the analytes. [Pg.499]

Noncovalent approaches can usually preserve the structures and properties of carbon nanotubes after functionalization17 (though not necessarily the near-infrared absorption characteristics due to well-established doping effects), thus are equally important to the biocompatibilization and bioapplications of nanotubes.15 Among commonly employed noncovalent schemes are surfactant dispersion,18 tt-tt stacking with aromatic compounds,19 and polymer wrapping.20... [Pg.200]

Paper is increasingly recycled. In 2005, the recycling rate reached 51.5%. Current AF PA guidelines target the return of 55% consumer waste paper into new paper production by 2012. Various processes have been developed to de-ink waste papers that carry a wide range of inks and coatings.293,294 Most de-inking is accomplished by the use of surfactants, dispersion and flotation. [Pg.705]

Mayonnaise. Mayonnaise is an oil-in-water emulsion prepared generally by using either whole egg or egg yolk. Instead of these, gelatin-Leu-OCi2 (15 min) (see Table IV) was tried as an emulsifying surfactant to prepare a mayonnaise-like food. Tween-60 as well as whole egg and egg yolk were used as controls. The final adopted ingredient composition was as follows 54 g soybean oil 0.9 g table salt 10 g surfactant dispersion. To prepare surfactant dispersions of two different concentra-... [Pg.215]

In addition to their traditional applications as surfactants, dispersants, etc., amphiphilic polymers have recently been attracting active interest in terms of their behavior at liquid-liquid, solid-liquid, and other interfaces (micellization, segmental conformation, etc.), along with their biocompatibility. In this section, amphiphilic block copolymers alone are briefly discussed. Graft and multiarmed polymers with amphiphilic arms will be treated later in this chapter (Section VI). [Pg.398]

Just because a surfactant adsorbs on the surface of a ceramic powder does not mean that it will stabilize the dispersion. The adsorbed surfactant will certainly help prevent the reagglomeration of the ceramic powder, like any adsorbed species, but the colloid stability of the ceramic powder-surfactant dispersion must be considered separately. Colloid stability is the subject of Chapter 10 of this book. [Pg.413]

Fig. 2 shows a schematic of a set of contrast variation SANS experiments that could be performed to determine the detailed molecular architecture of a micelle, assuming that the various deuterated forms are available. Fig. 2A shows micelles formed from fully hydrogenous surfactant dispersed in D2O In this case, the information obtained from the SANS experiment is primarily about the whole micelle, i.e., its shape and size. Fig. 2B shows the micelles formed by the chain-deuterated version of the surfactant in D2O In this experiment, information is mainly obtained about the head group region (shell) of the micelle. Finally Fig. 2C shows the micelles formed from the chain-deuterated version of the surfactant in H2O In this case, information is obtained about the chain region of the surfactant. It is possible to simultaneously fit the SANS data obtained for these three systems to obtain a self-consistent, detailed picture of the size. [Pg.1050]

Poly(dimethylsiloxane-co-oxyethylene-co-oxypropylene) is used as a surfactant, dispersant, and wetting agent, while poly[bisphenol A bis(oxyranylmethyl) ether]-co-poly(dimethylsiloxane) is used as an epoxy resin. More complicated silicone copolymers also were synthesized such as the silicone polyetherimide shown below ... [Pg.661]

Pileni [44] has reviewed the extensive work from her group on the use of reverse micelles as nanoscale reaction chambers within which nanoparticles can be prepared. In a system of water and surfactant dispersed in oil, under suitable conditions, the water forms spherical droplets of radius Rw given by ... [Pg.99]

For the formulation of suspensions, the hydrophobic or hydrophilic solid is dispersed in a aqueous or nonaqueous medium to produce a system that covers a wide particle size range, typically 0.1-5 pm. This process requires the presence of a surfactant (dispersant) that satisfies four criteria (i) wetting of the powder by the Uquid (if) the dispersion of aggregates and agglomerates into single units (iii) comminution of the large particles into smaller units and (iv) stabilisation... [Pg.1]
