Wet‐Spun PEDOT/CNT Composite Hollow Fibers as Flexible Electrodes for H 2 O 2 Production**

Composite material hollow antiresonant fibers.

We study novel designs of hollow-core antiresonant fibers comprising multiple materials in their core-boundary membrane. We show that these types of fibers still satisfy an antiresonance condition and compare their properties to those of an ideal single-material fiber with an equivalent thickness and refractive index. As a practical consequence of this concept, we discuss the first realization ...

Kinetics of HO 2 + HO 2 ! H 2 O 2 + O 2 : Implications for Stratospheric H

[1] The reaction HO2 + HO2 ! H2O2 + O2 (1) has been studied at 100 Torr and 222 K to 295 K. Experiments employing photolysis of Cl2/CH3OH/O2/N2 and F2/H2/O2/N2 gas mixtures to produce HO2 confirmed that methanol enhanced the observed reaction rate. At 100 Torr, zero methanol, k1 = (8.8 ± 0.9) 10 13 exp[(210 ± 26)/T] cm molecule 1 s 1 (2s uncertainties), which agrees with current recommendations...

Enhancement of composite performance by hollow polyester fibers

Graphene/polyaniline woven fabric composite films as flexible supercapacitor electrodes.

We report the design and preparation of graphene and polyaniline (PANI) woven-fabric composite films by in situ electropolymerization. The introduction of PANI greatly improves the electrochemical properties of solid-state supercapacitors which possess capacitances as high as 23 mF cm(-2), and exhibit excellent cycling stability with ∼ 100% capacitance retention after 2000 cycles. The devices h...
