“…The spinning solutions were prepared by dissolving TPU (7 wt%) and TBAC (1 wt%) in DMF with vigorous stirring over 10 h. TBAC was added in order to obtain nanobers with tree-like structures. 30 In order to reduce the solution viscosity and increase the solubility of TPU, a small amount of LiCl was introduced into the solution, 31,32 and then the mixed spinning solution was transferred into a syringe (10 mL). A voltage of 45 kV was applied in the experiment using a high voltage power supply (DW-P503-4ACF1, Tianjin, China).…”

In this study, a thermoplastic polyurethane (TPU) tree-like nanofiber membrane was fabricated via one-step electrospinning by adding a small amount of tetrabutylammonium chloride (TBAC). On the basis of the "push and pull" effect, double-layer membranes composed of pure TPU nanofiber membranes (hydrophobic) and TPU/TBAC tree-like nanofiber membranes (hydrophilic) were prepared by the direct electrospinning compounding method. The double-layer membranes were used as waterproof breathable materials with moisture unidirectional transport properties and good shielding properties. The water resistance, mechanical, waterproof, moisture permeability, air permeability, air filtration and moisture unidirectional transport performances of the double-layer membranes were tested. The results showed that the double-layer TPU membranes displayed good performances compared with the existing products on the market; they provide a new approach for the development of waterproof breathable materials.

“…This was because the increase of conductivity caused by the increase of the TBAC concentration was beneficial to the splitting of the charged jet [36,37]. The mechanism for the formation of the tree-like nanofibers has been reported in our previous paper [33]. Typically, for the electrospinning process of pure PVDF solution (Figure 2a), the jet followed a direct path on its way for certain a distance, and then whipped significantly to form a series of coils.…”

“…The exhaustive methods were reported in our published paper [33]. Typically, PVDF solution at a concentration of 17 wt % was prepared by dissolving PVDF powder in DMF/acetone mixture at a ratio of 3/1 (v/v) by vigorous stirring.…”

“…Wang et al [32] reported scaffold-like structured polyacrylonitrile (PAN)/silica nanofiber membranes by regulating the jet number ratios of various concentrations of PAN solutions via multi-jet electrospinning, and the membrane showed excellent filtration properties. In our previous works, a novel polyvinylidene fluoride (PVDF) tree-like nanofiber membrane (PVDF-TLNM) was fabricated via one-step electrospinning for the first time [33]. Previous studies have demonstrated that the PVDF-TLNM exhibited small pore size, excellent mechanical properties and a good organic solvent–resistance performance.…”

A novel polyvinylidene fluoride (PVDF) tree-like nanofiber membrane (PVDF-TLNM) was fabricated by adding tetrabutylammonium chloride (TBAC) into a PVDF spinning solution via one-step electrospinning. The structure of the prepared membranes was characterized by field emission scanning electron microscopy (FE-SEM), Fourier transform infrared spectroscopy (FT-IR) and pore size analysis, and the hydrophilic property and microfiltration performance were also evaluated. The results showed that the tree-like nanofiber was composed of trunk fibers and branch fibers with diameters of 100–500 nm and 5–100 nm, respectively. The pore size of PVDF-TLNM (0.36 μm) was smaller than that of a common nanofiber membrane (3.52 μm), and the hydrophilic properties of the membranes were improved significantly. The PVDF-TLNM with a thickness of 30 ± 2 μm showed a satisfactory retention ratio of 99.9% against 0.3 μm polystyrene (PS) particles and a high pure water flux of 2.88 × 104 L·m−2·h−1 under the pressure of 25 psi. This study highlights the potential benefits of this novel PVDF tree-like nanofiber membrane in the membrane field, which can achieve high flux rates at low pressure.

“…6,7 Heterogeneous nonwovens, which were characterized with the branched networks made of micro-nanofibers, have been studied widely. [8][9][10][11] The branched network structure is common in nature, such as the vascular systems of animals, rivers, trees, and leaf veins of plants. In addition, successful branched engineering materials including the fabrics with tree-like structure have been developed for exceptional properties in water transportation.…”

Previous research has shown that the branch radii of branched network were optimized for driving water with minimum flow resistance. 14,15 Murray 16 reported the optimal radius ratio between the parent and daughter branches for the least expenditure of energy, as shown in equation (1). Furthermore, the driving force for the liquid in fabrics was capillary force, which was dependent on the branch microstructure, such as the branch diameter, branch
