Bioinspired Bola Polysiloxane for Wettability, Breathability, and Softness in Fabrics

Abstract

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.

Ternary Siloxane Copolymers Based Tough Elastomer under Ultralow Temperatures Condition

“…With the continuous exploration of the Earth and extraterrestrial space, human beings are exposed to increasingly extreme environments, among which ultralow temperature conditions are one of the main challenges. − Silicone elastomers, characterized by exceptional resistance to high and low temperatures, − radiation, , and ultraviolet light, , as well as insulation, − air permeability, , and physiological inertness − properties, find widespread application in various fields, including electronic/electrical, aerospace, petrochemical, construction, transportation, and daily chemical industries. Notably, ethyl silicone rubber has attracted increasing attention as the elastomer material with the lowest known glass transition temperature. , Derived from the cross-linking of linear polydiethylsiloxane (PDES), with −Si–O–Si– as the main chain and –CH 2 CH 3 as the side group, ethyl silicone rubber exhibits a glass transition temperature of −145 °C.…”

A Fusion of Molecular Imprinting Technology and Siloxane Chemistry: A Way to Advanced Hybrid Nanomaterials

“…The utilization of the molecularly imprinted technology to organosilicones, such as siloxanes (and polysiloxanes), could significantly enhance the application capabilities of the latter materials. It should be pointed out that siloxanes have found countless and diverse applications, not only in biomedicine and pharmaceutical fields [ 69 ] but also in personal care products and cosmetics due to the non-toxicity and biocompatibility of siloxane compounds [ 70 ], as well as other areas, such as electronic manufacturing, automotive industry, textile products, construction materials, medical equipment, and food processing ( Figure 1 ) [ 69 , 71 , 72 , 73 , 74 , 75 , 76 , 77 , 78 , 79 ]. It has to be underlined that such broad application capabilities of siloxanes are possible because of their extraordinary properties such as flexibility and rubber-like elasticity, fracture toughness, mechanical and chemical durability, thermal stability, compressive strength, optical transparency, and amphiphilicity, among others [ 80 ].…”
