“…The spinning is conducted at the spinning voltage of 15 kV and the syringe advancing speed of 2 ml/h. The distance between the needle tip and the fiber collection device is 13 cm, and the winding speed is 200 r/min (Xu et al, 2019;Cao et al, 2020). The electrospun fiber of aforementioned spinning solution under same process conditions was named as PLLA, PDLA, sc-PLA, sc-PLA + 0.15 wt%AgNPs, sc-PLA + 0.30 wt%AgNPs, sc-PLA + 0.45 wt%AgNPs, and sc-PLA + 0.60 wt%AgNPs electrospun fiber membranes.…”

Stereo-complexed polylactide (sc-PLA) fibers with excellent heat resistance and antibacterial properties were prepared by electrospinning. Due to poor heat resistance, common poly(L-lactide) (PLLA) fibers have poor dimensional stability at high temperatures and cannot be sterilized and recycled as a medical filter material. In this research, PLLA/poly(D-lactide) (PDLA) blends doped with silver nanoparticles (AgNPs) were electrospun to obtain the sc-PLA fibers. The effect of thermal induction temperature on the crystalline structure and thermal properties of sc-PLA fibers was investigated. Moreover, the influence of the addition amount of AgNPs on the crystal structure of sc-PLA fibers was studied, and the antibacterial properties of the sc-PLA fibers with different addition amounts of AgNPs were analyzed. The thermal induction is beneficial to the formation of stereo-complexed crystals of sc-PLA fibers, and finally completely stereo-complexed PLA fibers were obtained. The melting temperature of the completely stereo-complexed PLA fibers was 50°C higher than that of the PLLA fibers; therefore, the sc-PLA fibers have better heat resistance. The addition of AgNPs was conducive to the formation of stereo-complexed crystals of sc-PLA fibers. In addition, the antibacterial rate of sc-PLA fibers against E. coli and S. aureus was 99.99 ± 0.01% when the addition amount of AgNPs was only 0.15 wt%. The fiber membrane obtained in this experiment can be used as a reusable filter material, and the sc-PLA fiber membrane has broad application prospects in the biomedical field.

“…Nanocomposite fibers have also been successfully realized through electrospinning. − Chen et al produced composite nanofiber membranes of poly- d l -lactide (PDLLA) and hydroxyapatite (HA) by electrospinning and fabricated their respective composites through hot pressing. These composites are considered to have high potential as bone substitutes.…”

Fiber-reinforced polymer composites find extensive applications ranging from sporting goods to aircraft components. Nonetheless, the weak interlaminar properties of laminated composites impose challenges in the design of primary load-bearing structures. The incorporation of additives (e.g., particles, films, and fibers) can overcome these limitations, offering additional functionalities to composites. Interleaving in composites generally refers to the incorporation of materials at the interface between two fiber plies so as to improve various properties. Being a simple technique to integrate in the production line, interleaving is recognized as an industrially significant and commercially viable method of modifying laminated composites. In this Review, an effort to assess state-of-the-art research on interleaving is attempted. Methods, applications, and the influence of interleaves on various properties of composites are also discussed. Data from the most recent research works on interleaved composites are compiled in an attempt to aid and encourage further developments among industries and academia.

“…Electrospinning process is the common way to fabricate 1D conductive nanofibers [ 188 – 198 ]. Electrospinning works in a similar way to e-Inkjet, where a strong electric field between the nozzle and the printing substrate transfers the solution from the nozzle to the printing platform.…”

Graphic abstract Silver nanowires (AgNWs), as one-dimensional nanometallic materials, have attracted wide attention due to the excellent electrical conductivity, transparency and flexibility, especially in flexible and stretchable electronics. However, the microscopic discontinuities require AgNWs be attached to some carrier for practical applications. Relative to the preparation method, how to integrate AgNWs into the flexible matrix is particularly important. In recent years, plenty of papers have been published on the preparation of conductors based on AgNWs, including printing techniques, coating techniques, vacuum filtration techniques, template-assisted assembly techniques, electrospinning techniques and gelating techniques. The aim of this review is to discuss different assembly method of AgNW-based conducting film and their advantages. Conducting films based on silver nanowires (AgNWs) have been reviewed with a focus on their assembly and their advantages.
