Zeqi Chen, Chengzhuo Wei, Weida Rao, Lingling Fan, more

Fibers and Polymers > 2018 > 19 > 11 > 2344-2350

An electrothermochromic fabric triggered by electric voltages was prepared by combining the electric heating feature of conductive polypyrrole (PPy) and the temperature-response color-changing feature of thermochromic inks. PPy was deposited selectively on the carbon-coated side of the sailcloth fabric via electrochemical polymerization. Thermochromic inks were painted on the reverse side with white...

Cellulose > 2017 > 24 > 11 > 5187-5196

Paper with color changes caused by applied electric voltages was fabricated by combining the electric heating feature of conductive polypyrrole (PPy) and the temperature response color-changing feature of thermochromic ink. Highly conductive PPy was deposited selectively on the graphite-coated side of the paper via electrochemical polymerization. Thermochromic ink was coated on the reverse side with...

An all-solid-state yarn supercapacitor using cotton yarn electrodes coated with polypyrrole nanotubes

Chengzhuo Wei, Qi Xu, Zeqi Chen, Weida Rao, more

Carbohydrate Polymers > 2017 > 169 > C > 50-57

A novel all-solid-state yarn supercapacitor (YSC) has been fabricated by using the cotton yarns coated with polypyrrole (PPy) nanotubes. The interconnected network structure of PPy can increase the surface area as well as the electrode/electrolyte interface area, thus resulting in improved electrochemical performance. For the proposed YSC, a high areal-specific capacitance of 74.0mFcm⁻² and a desirable...

A bacterial cellulose/Al₂O₃ nanofibrous composite membrane for a lithium-ion battery separator

Qi Xu, Chengzhuo Wei, Lingling Fan, Shuo Peng, more

Cellulose > 2017 > 24 > 4 > 1889-1899

The bacterial cellulose (BC)/Al₂O₃ nanofibrous composite membrane as a lithium-ion battery separator has been successfully prepared by coating Al₂O₃ on the BC nanofibers through a simple in situ thermal decomposition of Al(NO₃)₃ · 9H₂O. Thermal treatment tests show that the BC/Al₂O₃ composite membrane is thermally stable at a high temperature of 200 °C while great shrinkage is observed for the commercial...

Flexible polypyrrole/copper sulfide/bacterial cellulose nanofibrous composite membranes as supercapacitor electrodes

Shuo Peng, Lingling Fan, Chengzhuo Wei, Xiaohong Liu, more

Carbohydrate Polymers > 2017 > 157 > C > 344-352

Polypyrrole (PPy) and copper sulfide (CuS) have been successfully deposited on bacterial cellulose (BC) membranes to prepare nanofibrous composite electrodes of PPy/CuS/BC for flexible supercapacitor applications. The introduction of CuS remarkably improves the specific capacitance and cycling stability of BC-based electrodes. The specific capacitance of the supercapacitors based on the PPy/CuS/BC...

Shuo Peng, Qi Xu, Lingling Fan, Chengzhuo Wei, more

Synthetic Metals > 2016 > 222 > PB > 285-292

Bacterial cellulose (BC) has attracted much attention due to its low-cost, high specific surface area and ample porosity. In this work, polypyrrole (PPy) and cobalt sulfide (CoS) have been deposited on BC membranes to prepare the nanofibrous composite electrodes of PPy/CoS/BC with excellent flexibility for supercapacitor application. The introduction of CoS remarkably improves the pseudocapacitance...

Polypyrrole-coated cotton fabrics prepared by electrochemical polymerization as textile counter electrode for dye-sensitized solar cells

Qi Xu, Meixia Li, Peng Yan, Chengzhuo Wei, more

Organic Electronics > 2016 > 29 > C > 107-113

Textile-based wearable electronics provides the combined advantages of both electronics and textiles, such as flexibility, stretchability and lightweight. Much effort has been dedicated to achieve flexible photovoltaic power for wearable electronics. Here, we have demonstrated polypyrrole (PPy) coated cotton fabrics as textile counter electrode (CE) in dye-sensitized solar cells (DSSCs). PPy is deposited...

Polypyrrole/nickel sulfide/bacterial cellulose nanofibrous composite membranes for flexible supercapacitor electrodes

Shuo Peng, Lingling Fan, Chengzhuo Wei, Haifeng Bao, more

Cellulose > 2016 > 23 > 4 > 2639-2651

The increasing trend of portable electronic products requires the development of portable and flexible energy-storage devices, such as flexible supercapacitors. In this study, we deposited polypyrrole (PPy) and nickel sulfide (NiS) on bacterial cellulose (BC) nanofibrous membranes to be used as flexible supercapacitor electrodes. The obtained PPy/NiS/BC composite membranes are highly conductive, with...

Quantitative structure–property relationship study of β-cyclodextrin complexation free energies of organic compounds

Qi Xu, Chengzhuo Wei, Ruina Liu, Shaojin Gu, more

Chemometrics and Intelligent Laboratory Systems > 2015 > 146 > C > 313-321

A quantitative structure–property relationship (QSPR) study was performed between β-cyclodextrin complexation free energies and descriptors representing the molecular structures of organic guest compounds. The entire set of 218 compounds was divided into a training set of 160 compounds and a test set of 58 compounds by DUPLEX algorithm. Multiple linear regression (MLR) analysis was used to select...
