Electrodes For Supercapacitors

AbstractMany hybrid electrodes for supercapacitors (SCs) are a reckless combination without proper structural design that keeps them from fulfilling their potential. Herein, we design a reduced graphene oxide/poly(3,4-ethylenedioxythiophene)/polyaniline (RGO/PEDOT/PANI) hybrid with hierarchical and porous structure for high-performance SCs, where components fully harness their advantages, forming an interconnected and conductive framework with substantial reactive sites.Thus, this hybrid achieves a high capacitance of 535 F g−1 along with good rate capability and cyclability. The planar SC based on this hybrid deliver an energy density of 26.89 Wh kg−1 at a power density of 800 W kg−1. The linear SC developed via modifying a cotton yarn with the hybrid exhibits good flexibility and structural stability, which operates normally after arbitrary deformations. This work provides a beneficial reference for developing SCs.

Purpose The purpose of this paper is to optimize the linear densities of polyester yarn and filament for inner layer and elastane for middle layer with cotton yarn outer layer in plain knitted plated structure for hot and dry environment clothing. Design/methodology/approach Three levels of polyester yarn linear densities (11.1, 8.4 and 5.6 Tex), filament linear densities (0.8, 1.55 and 2.3 Decitex) and elastane (0, 4 and 8 percent) with 14.75 Tex cotton yarn have been used to knit 15 single jersey plated fabrics based on Box and Benhens experimental design with same loop length. Three cotton–elastane core-spun fabrics were also produced. All the fabrics were analyzed for moisture and ergonomic comfort properties and wet fabric coefficient of friction. Findings The increase in elastane content and yarn linear density decreases water vapor and air permeability; the increase in filament linear density decreases wicking rate and water absorbency. The optimum solution is 5.55 Tex polyester yarn of 0.8 Decitex filament as inner layer and 14.75 Tex cotton yarn as outer layer which gives good heat and moisture transfer without stickiness. Research limitations/implications The implication of this paper is to study thinner polyester, polypropylene and polyethylene fabrics with more micro pores as skin contact layer for quicker heat and moisture transfer. Practical implications Outward wickability of sweat from the skin is the prime requirement of all skin contact layer fabrics. Social implications It shifts the social attitude of most comfortable fabric to polyester–cotton plated for hot and dry climate. Originality/value This paper employs a more practical method for the selection of fabric.

The artificial neural network model is used to predict the breaking elongation of polyester/cotton ring spinning yarn in this paper. In order to achieve the objective, a series of trials is conducted. The prediction values and actual test values of which are found to be rather close. Therefore, the artificial neural network model proves to be more feasible in the prediction of breaking elongation of polyester/cotton ring spinning yarn.

Pre Treatment

Sizing of the cotton yarn is essential to reduce breakage of the yarn due to abrasion during weaving process. The sizing agent on the woven fabric after weaving needs to remove completely before the next textile production process of dyeing and finishing. So, water soluble sizing agent is easy to handle and easy to desizing for pre-treatment of woven fabric. In this work, different types of water soluble tamarind seed kernel based sizing formulations (assigned by A, B and C) were made and applied on cotton yarn to investigate the effect on the tensile properties of sized and unsized cotton yarns. Cotton yarn treated with size B formulation shows the better tensile properties than the application of size A and size C formulation. The effect of lubricant has also been investigated and shows that the addition of lubricant decreases the tensile properties of the cotton yarn.

This article is concerned with the development of a compact system suitable for producing compact roving. The objective is to reduce twist and improve the performance of roving in the subsequent processes. Combed compact cotton yarn with a linear density of 9.84tex was spun from compact and conventional roving. In order to conclude that compactness had been formed in roving, two special tests, namely the minimum twist of cohesion and roving cohesion strength were determined. Yarns produced from conventional and compact roving were compared for their strength, evenness and hairiness. The results show that there was an improvement in the strength and hairiness of the compact yarns produced from compact roving when compared to conventional yarns.
