Graphene is now the most attractive carbon-based material. Integration of 2D graphene sheets into macroscopic architectures such as fibers illuminates the direction to translate the excellent properties of individual graphene into advanced hierarchical ensembles for promising applications in new graphene-based nanodevices. However, the lack of effective, low-cost and convenient assembly strateg...

A slender 1{D model for laments of liquid crystalline polymers (LCPs) is applied to simulate isothermal ber spinning of materials with internal orientation. The model and predictions focus on the hydrodynamic{orientation interactions in spinning ows, isolated from other signi cant spinline e ects of temperature, crystallization and phase changes. An important practical feature of the model is t...

The cellulosic fiber-based sustainable textile industry needs greener alternatives to the existing hydrophobization approaches—which are essentially based on nonrenewable and expensive hydrophobizing agents adversely impact environment. Herein, we report production of novel hydrophobic cellulose fibers produced by incorporating nature-derived additives—betulin (BE) betulinic acid (BA) using Ion...

Abstract Microscale fibrous materials with high surface areas and ordered structures have attracted widespread attention recently. Microfluidic spinning technology that can effectively control the sizes, structures, material compositions of fibers has emerged as a robust approach for fabrication high‐performance fibers. In this review, microfluidic used to prepare in terms preparation principle...

polypropylene / polystyrene blends containing montmorillonite (mmt) were prepared using a twin screw extruder followed by fiber spinning. the melt intercalation of pp and ps alloys was carried out in the presence of a compatibilizer such as maleic anhydride-g-polypropylene (mpp). the crystallization morphology, thermal behaviors and mechanical properties of polypropylene/polystyrene (pp/ps) nan...

metal spinning as a kind of manufacturing process has capability to shape hollow components. in present work shear spinning process is used to formplates into conical shapes. moreover, the aim of this research is to demonstrate the impact of the process parameters (i.e. feeding rate and spindle speed) on wall thickness. this approachwas done by experimental and finite elements method. the resul...

Production of high strength carbon fibers from bio-derived precursors is of topical interest. Recently, we reported on dry-spinning of a partially acetylated softwood kraft lignin to produce carbon fibers with superior properties, but the thermo-oxidative stabilization step required a long time due to a slow heating rate needed to prevent the fibers from being heated too rapidly and sticking to...

Polydiacetylene (PDA) is an attractive conjugated material for use in biosensors due to its unique characteristic of undergoing a blue-to-red color change in response to external stimuli. 10,12-Pentacosadiynoic acid (PCDA) and poly (ethylene oxide) (PEO) were used in this study to develop fiber composites via an electrospinning method at various mass ratios of PEO to PCDA, solution concentratio...
