“…Thanks to the presence of the Si-H bond, it is possible to attach all kinds of substituents, e.g. amino [1][2][3][4], epoxycarbo [5][6][7], aryl and methacrylic [8,9] or polyether [4,10,11] groups. Modification of polysiloxanes with organic groups provides a wide range of hybrid materials combining the properties of polysiloxanes (thermal resistance, oxidation resistance, gas permeability, low surface tension, excellent dielectric properties, physiological neutrality and moisture resistance) with those of organic functional groups.…”

The trisiloxane polyether surfactant (3-[3-(hydroxy)(polyethoxy)propyl]-1,1,1,3,5,5,5 -heptamethyltrisiloxane) (TS-EO12) was successfully synthesized by a hydrosilylation reaction in the presence of Karstedt catalyst. The structural analysis of the surfactant was done by 1H-NMR, 13C-NMR, 29Si-NMR and FT-IR analysis. In addition the thermal stability of TS-EO12 was studied by the thermogravimetric measurements. On the one hand the surface properties of TS-EO12 at the water-air interface were investigated by surfactant aqueous solutions surface tension measurements carried out at 293 K, 303 K and 313 K, and on the other the aggregation properties were analyzed based on the solubilization properties of TS-EO12 aggregates at different temperatures. On the basis of the obtained thermodynamic parameters of adsorption and micellization of studied surfactant the temperature impact on its surface and volume properties were deduced. It was proved that the tendency of the studied surfactant molecules to adsorb at the water-air interface and to form micelles weakens with decreasing temperature. It was also concluded that the structure of the adsorption layer changes with temperature. Optical microscopy measurements were used for the TS-EO12 micelle morphology determination.

The wettability, breathability, and softness of fabrics are difficult to effect synergistically, so they cannot meet the requirements of personal comfort. Here, inspired by some amazing superhydrophilic structures in nature, a synergistic strategy is reported to create a novel Bola quaternary ammonium polyether polysiloxane (BQPEPS) with a water transport channel and softness performance with a unique inverted U shape, overcoming previous limitations. The results showed that the friction coefficient, bending rigidity, and softness were 0.153, 39.75 mN m, and 553 mN, respectively, which are better than those of commercially available products of two other structures. After 40 cycles of washing, the smoothness, stiffness, and softness of the BQPEPS-treated fabrics remained at 88%, 67.7%, and 63.5%, respectively. Moreover, the total wetting time of the BQPEPS-treated fabrics was less than 1 s, and the water vapor transmission was 792 g m −1 in 24 h. Overall, the successful synthesis of Bola polysiloxane should provide personal comfort and thereby exhibit great potential in practical applications.

A series of ester‐containing cationic silicone softeners with different alkyl chain lengths were successfully synthesized to manufacture antibacterial cotton fabrics. The relationship between the molecular structure and the softener's mechanical and physical properties was investigated. This study demonstrated that the fabrics treated with SiQCnCl softeners bearing short alkyl chains (n = 9, 11, and 13) showed better instantaneous hydrophilicity, close to that of a pristine cotton fabric. However, the SiQC17Cl‐treated fabrics with long alkyl chains showed the best softness, exceeding that achieved with the conventional finishing agent D1821. And the whiteness index of the fabrics decreased with the use of longer fabric finishing times, with the SiQC15Cl‐treated fabrics exhibiting the highest whiteness index. Moreover, it was also found that SiQCnCl‐treated fabrics showed higher antibacterial activity against Staphylococcus aureus than Escherichia coli, with the SiQC13Cl‐treated fabrics exhibiting the best antibacterial activity. In addition, a model depicting the antibacterial action of the prepared fabrics was illustrated. Finally, it was discovered that the synthesized ester‐containing cationic silicone softener showed better primary biodegradability than D1821 and DC‐5700, exceeding 80% after a 120‐h degradation.
