Triboelectric nanogenerators (TENGs) are emerging as a sustainable and environmentally friendly approach for energy harvesting self-powered sensing, because of their diverse material options, simple structure, efficient conversion. However, developing tribopositive materials with both high-charge-inducing high-charge-trapping capabilities remains significant challenge. Herein, high-performance TENG is developed based on polyaniline (PANI) embedded polyacrylonitrile (PAN) nanofiber membrane...
With the continuous improvement of standard living, people are increasingly inclined towards natural, green, and environmentally friendly products. Plant-based products that safe, non-toxic, beneficial to human health often more favored. Poly(lactic acid) (PLA) is a polymer obtained through lactate polymerization using renewable plant resources such as corn has excellent biocompatibility biodegradability. It widely used in field food packaging. Wormwood oil (WO) an extracted from stems...
The segmented-pie composite fibers can be separated by high-pressure hydroentanglement to form a high-strength, lightweight microfiber nonwovens. Nowadays, it is an urgent problem develop easily split and reduce the energy consumption of hydroentangled in bicomponent spunbond technology. Herein, molecular dynamics simulations were first performed for polyester polyamide 6. results reveal that surface adsorption between polymers decreases with decrease polymer chain regularity, cohesion...
Diffusion is an important filtration mechanism of fibrous filters for removing fine particles from gas streams. An analytical model proposed in this work, based on fractal theory, to quantify the effective diffusion coefficient (EDC) across micro/nanofibrous with a layered structure. To show influence macroscopic parameters EDC, present models are expressed terms fiber diameter. Polyacrylonitrile (PAN) nanofibers were prepared by electrospinning melt-blown polypropylene (PP) microfiber...
Compared to natural leather, microfiber synthetic leather has many excellent qualities, such as chemical resistance and physical mechanical properties. However, preparation of with a high water vapor transmission rate (WVT), moisture absorption wearing comfort property is still challenge. In this study, we prepared thermoplastic polyurethane (TPU)/sulfonated polysulfone (SPSf) electrospun nanofibers applied them base (MSLB). The effects TPU/SPSf nanofiber content on the structure properties...
The microfiber synthetic leather base (MSLB) was prepared by mixing hollow segmented pie microfibers and polyacrylonitrile electrospun nanofibers. Micro/nano hybrid to simulate the three-dimensional (3D) structure of natural leather. diameter nanofibers 950 nm, 450 nm 200 respectively. effects different diameters on performances MSLB were investigated. results indicated that randomly dispersed in MSLB. Differential scanning calorimetry further demonstrated presence MSLB, thermogravimetric...
Compared with natural leather, microfiber synthetic leather has many excellent properties such as chemical resistance and physical mechanical properties.

Bicomponent spunbond hydroentanglement technology can break the interface between two components by physical extrusion and shearing, thereby realizing green efficient production of high-strength microfiber nonwoven materials. Herein, we report a soft fluffy bicomponent material using high-shrinkage polyester/polyamide 6 (HSPET/PA6) as bicomponent. HSPET/PA6 hollow segmented pie composite fibers with different volume ratios were prepared technology, HSPET PA6 segments alternately arranged,...
Polyester/polyamide 6 hollow segmented pie bicomponent spunbond hydro-entangled microfiber nonwovens (PET/PA6) with a microfilament structure have recently emerged in many markets around the world due to their green, high-strength, and lightweight properties. However, PET/PA6 is highly hydrophobic, which inhibits its large-scale application at present. In order enhance hydrophilic performance of PET/PA6, methods been applied, but effects are not obvious. Ultraviolet (UV) irradiation...
