Two-dimensional (2D) MXene-based nanofiltration membranes could sustainably and rapidly produce clean water. However, the challenges related to severe swelling of MXene in water should be overcome before practical application. In this work, negatively charged membrane is modified by positively polyethyleneimine (PEI) with various PEI:MXene ratios. The PEI-MXene deposited on a polyacrylonitrile ...

Carbon fibers (CFs) are made mostly from a non-environmentally friendly polyacrylonitrile (PAN) and little rayon. PAN-based CFs, require huge amount of energy for its production aside contributions to the global CO2 emission. Therefore, there is recourse more environmentally sources CFs biomass. Recently lignin has been recognized as potential renewable raw material carbon replace PAN-based. Th...

Textiles can provide effective protection against UV radiation because they reflect, absorb and scatter solar wavelengths. Properly designed, they significantly increase the area of covered skin. The optimal combination of thickness, fabric density, mass per unit area, knitted structure, yarn type and yarn linear density, facilitate the production of textiles with high UV protection properties....

Acoustic sensors show a wide application in diverse fields. However, it is still challenge to develop highly sensitive transducing materials for the detection of low-to-middle decibel sounds. Herein, first time remarkable property an acoustic sensor based on electrospun polyacrylonitrile (PAN) nanofibers recognition human voices reported. The nanofiber device shows sensitivity as high 23 401 mV...

The electrolyte for dye-sensitized solar cells (DSSCs) is subject of constant innovation, as the problems leakage and drying greatly reduce long-term stability a device. One possible way to solve these use gel polymer electrolytes (GPEs) with gelling structure, which offer different advantages based on used polymers. Here, potential GPE systems dimethyl sulfoxide (DMSO) solvent low-cost, non-to...

Pitch-based carbon fiber reinforced epoxy composites are used in specialized applications for their high-modulus and thermal conductivity; however, little data on fatigue performance available the open literature. In this study, behaviors of ultra-high-modulus pitch-based standard-modulus polyacrylonitrile (PAN)-based were compared woven quasi-isotropic matrix subject to uniaxial tension. It wa...

Objective(s): Since the electric field is the main driving force in electrospinning systems, the modeling and analysis of electric field distribution are critical to the nanofibers production. The aim of this study was modeling of the electric field and investigating the various parameters on polyacrylonitrile (PAN) nanofibers morphology and diameter. Methods:</st...

Binders are electrochemically inactive components that have a crucial impact in battery ageing although being present only small amounts, typically 1–3 % w/w commercial products. The electrochemical performance of can be tailored via these materials by optimizing the electrode integrity and surface chemistry. Polyacrylonitrile (PAN) for LiNi0.5Mn1.5O4 (LNMO) half-cells is here investigated as b...
