Controllable deposition distance of aligned pattern via dual-nozzle near-field electrospinning

AIP Advances (2017)

Zhifeng Wang Xindu Chen Jun Zeng Feng Liang Peixuan Wu

For large area micro/nano pattern printing, multi-nozzle electrohydrodynamic (EHD) printing setup is an efficient method to boost productivity in near-field electrospinning (NFES) process. And controlling EHD multi-jet accurate deposition under the interaction of nozzles and other parameters are crucial concerns during the process. The influence and sensitivity of various parameters such as the needle length, needle spacing, electrode-to-collector distance, voltage etc. on the direct-write patterning performance was investigated by orthogonal experiments with dual-nozzle NFES setup, and then the deposition distance estimated based on a novel model was compared with measurement results and proven. More controllable deposition distance and much denser of aligned naofiber can be achieved by rotating the dual-nozzle setup. This study can be greatly contributed to estimate the deposition distance and helpful to guide the multi-nozzle NFES process to accurate direct-write pattern in manufacturing process in future.

Fabrication of polyvinylidene fluoride/silver nanofiber membrane with antibacterial and anti-yellowing property

AIP Advances (2021)

Jun Zeng Han Wang Xindu Chen Peixuan Wu Xin Chen

At present, nanofiber antibacterial materials, especially silver antibacterial materials, are one of the most popular antibacterial materials. Nanofiber antibacterial materials are the most widely used materials due to their antibacterial spectrum and persistence. In fact, the storage and anti-yellowing properties of nanofiber antibacterial materials are of great concern in the application of industrial and consumer goods. However, there are few studies on the uniform preparation, storage, and anti-yellowing properties of antibacterial materials. Thus, we prepared nanofiber antibacterial materials by adding surfactants and studied the dispersion and storage time of the spinning solution. After spinning and forming the membrane, we tried to study the fiber morphology and environmental factors prepared by different proportions. Finally, we also tried to study the properties of the nanofiber membrane, such as contact angle, anti-yellowing, and antibacterial property. In a word, we explored the basic rules of material preparation, storage, and yellowing resistance so as to provide guidance for nanofiber antibacterial material industrial production.

Optimization of electric field uniformity of multi-needle electrospinning nozzle

AIP Advances (2019)

Ziming Zhu Peixuan Wu Zhifeng Wang Guojie Xu Han Wang

Multi-needle electrospinning technology is a method for mass production of nanofibers, which can improve the production efficiency of nanofibers by increasing the number and density of needles for multi-needle electrospinning. However, when the arrangement density of the needle is high, the electric field of the needle tip is not uniform, causing instability such as jet dripping and broken jet. In this paper, the electric field uniformity optimization problem of multi-needle electrospinning technology is used to simulate the needle tip electric field by using COMSOL finite element analysis software. The influence of the needle size and the dielectric material on the electric field of the tip was studied. Finally, the method of using dielectric material on the tip of the middle part of the needle is beneficial to the electric field uniformity. The uniformity of the needle tip electric field in the case of high-density arrangement of the needle is realized, and the nozzle is provided for mass production of nanofibers by multi-needle electrospinning.

Primary Frequency Control of Multiple ON/OFF Load Clusters Considering Capacity Uncertainty and Lock-time Constraint

IEEE Transactions on Smart Grid (2024)

Peixuan Wu Di Liu Guannan He Songyan Zhang Chao Lü

In modern power systems, load-side controllable resources, especially ON/OFF type controllable loads, have emerged as promising reserves for providing fast frequency support. This article presents a three-layer hierarchical control framework enabling multiple ON/OFF load clusters to actively participate in primary frequency control (PFC) with their control characteristics well considered. At the cluster-layer, the probability distribution of aggregate regulation capacity is estimated by state evolution model with no underlying information needed. At the aggregator-layer, optimal droop coefficient allocation for multiple clusters is achieved by minimizing the comprehensive cost objective with capacity chance constraints. At the device-layer, a self-governing mechanism is designed for each individual load to timely formulate and correctly conduct its own response plan according to upper-layer broadcast instructions. Consequently, the reliability of PFC with ON/OFF loads is significantly enhanced by taking capacity uncertainty and inherent lock-time constraint into account. Meanwhile, the communication requirements and user privacy damage are minimized while ensuring the final control accuracy. Steady-state and transient simulations further validate the effectiveness of the proposed upper-layer and device-layer PFC method respectively.

Fabrication and evaluation of controllable deposition distance for aligned pattern by multi-nozzle near-field electrospinning

AIP Advances (2018)

Zhifeng Wang Xindu Chen Jiarong Zhang Yaju Lin Kuan Li

To mass-volume fabricate micro- and nano-scales aligned pattern, multi-nozzle near-field electrospinning (NFES) direct-writing technology is well proposed as a high-efficiency method in electrohydrodynamic (EHD) printing process. However, the interference effect among adjacent nozzles and coupling effect of various parameters have restricted to investigate deposition characteristic of multi-nozzle NFES and control EHD multi-jet deposition accuracy. In order to improve the accuracy of EHD multi-jet deposition with high-efficiency printing process, the experimental result compared with theoretical method were discussed. In this work, the influence of multi-nozzle geometry distribution and electrospinning parameters on deposition characteristic was studied with multi-nozzle NFES setup, and nozzles were in linear array. The deposition distance and homogeneity of aligned nanofibers were measured and explained with coefficient of dispersion on electric field among nozzles by simulation. Moreover, deposition distance of multi-nozzle NFES process was evaluated by modified theoretical derivation based on our previous studies. The modified theoretical derivation showed a good agreement with experiment results, and indicated that multi-nozzle NFES could accurately and efficiently direct-write aligned array pattern in future.
