“…It can be observed that the agglomeration of SiO 2 nanoparticles appeared on the surface of nanofibers. The polarization and surface effect of SiO 2 nanoparticles aggravated the agglomeration of SiO 2 nanoparticles . The average nanofiber diameter of PI, PISi-1, PISi-2, PISi-3, PISi-4, and PISi-5 were 390 ± 41, 402 ± 47, 429 ± 60, 461 ± 75, 492 ± 102, and 537 ± 196 nm, respectively.…”

“…The polarization and surface effect of SiO 2 nanoparticles aggravated the agglomeration of SiO 2 nanoparticles. 46 The average nanofiber diameter of PI, PISi-1, PISi-2, PISi-3, PISi-4, and PISi-5 were 390 ± 41, 402 ± 47, 429 ± 60, 461 ± 75, 492 ± 102, and 537 ± 196 nm, respectively. The diameters of the nanofibers and the degree of unevenness of diameter distribution increased with the increase in the SiO 2 nanoparticle content.…”

Developing adsorption materials for organic solvents with both high adsorption capacity and recyclability provides a broad prospect for contaminated water treatment. In this study, PI/SiO2 composite nanofibrous sponges with hydrophobicity, high oil adsorption capacity, and excellent cycling performance fabricated by blow spinning have been reported. The improvement of hydrophobicity of PISi-3 was credited to the SiO2 nanoparticles, resulting in excellent oil adsorption capacity (103.95 g/g for ethanol, 320.99 g/g for motor oil, and 386.81 g/g for silicone oil). The recyclability after 10 cycles of PISi-3 was improved by 23% compared with the pure PI sponge owing to the supporting effect of SiO2 nanoparticles. Sponges with higher cycling performance could be obtained by regulating the temperatures of thermal treatment. PISi-3 after heat treatment at 450 °C exhibited good oil adsorption ability (98.12 g/g for ethanol, 261.92 g/g for motor oil, and 315.81 g/g for silicone oil) and excellent cycling performance. The adsorption capacity decreased by only 0.22% after 10 cycles. Therefore, the fabrication strategy of the sponges has great prospects in maritime oil spill recycling and industrial water treatment.

“…But there is no simple linear relationship between them. The experiment of using SiO 2 nanoparticles as fillers was carried out by Zhuo et al 46 Interestingly, they found that the TC of the composites did not show a single trend with the increase of SiO 2 content (0-5%) but first decreased and then increased while the minimum TC appeared when the SiO 2 nanoparticle content was 2%. The reason is that when the SiO 2 doping amount is less than or equal to 2%, the interfacial thermal contact resistance and thermal expansion do not match between the doped SiO 2 nanoparticles and matrix phases, while with a continuous increase in the doping amount, more SiO 2 nanoparticles would form an aggregate state, thus increasing the overall TC of the composites.…”

In recent decades, the interest in responsive fibrous structures has surged, propelling them into diverse applications: from wearable textiles that adapt to their surroundings, to filtration membranes dynamically altering selectivity, these structures showcase remarkable versatility. Various stimuli, including temperature, light, pH, electricity, and chemical compounds, can serve as triggers to unleash physical or chemical changes in response. Processing methodologies such as weaving or knitting using responsive yarns, electrospinning, as well as coating procedures, enable the integration of responsive materials into fibrous structures. They can respond to these stimuli, and comprise shape memory materials, temperature-responsive polymers, chromic materials, phase change materials, photothermal materials, among others. The resulting effects can manifest in a variety of ways, from pore adjustments and altered permeability to shape changing, color changing, and thermal regulation. This review aims to explore the realm of fibrous structures, delving into their responsiveness to external stimuli, with a focus on temperature, light, and pH.
