Dataset on structure and mechanical properties of electrospun polyacrylonitrile nanofibrous mesh reinforced by halloysite nanotubes

Abstract

The mechanical properties of electrospun polyacrylonitrile (PAN)-based membranes for ultrafiltration, such as oil–water separation and heavy metals from water, are often characterised in the dry state but little is known about the membrane properties in the hydrated state. This dataset comprised mechanical properties and structure-related properties of electrospun PAN-based membranes. The mechanical dataset described the yield strength and strain, stiffness, resilience energy, fracture strength, strain at fracture and fracture toughness of electrospun neat PAN and halloysite nanotube (HNT) reinforced PAN membranes in both hydrated and dry states. The data related to the hydrated state were derived from direct measurements of the mechanical properties of the PAN-based membrane using a novel environmental micromechanical tester. The structure-related dataset comprised electron micrographs and quantitative measurements (fibre diameter and pore diameter) derived from the micrographs. For further interpretation and discussion of the dataset, the reader is referred to the research data article, “Direct measurement of the elasticity and fracture properties of electrospun polyacrylonitrile/halloysite fibrous mesh in water” (Govindasamy et al., 2014).

“…The raw data required to reproduce these findings cannot be shared at this time as the data also forms part of an ongoing study. The processed data required to reproduce these findings are found in Ref [34].…”

“…Data derived for the structural properties, i.e. fibre diameter and pore diameter, can be found in Table and 2 in Ref [34].…”

“…Cellulose is a natural polymer and abundantly exists in renewable plants such as cotton and wood, therefore it has the advantages of accessibility and biodegradability, and becomes an irreplaceable raw material in textiles, packaging and construction industries (Jiao et Yu et al 2017). However, the strong hydrogen bonding network in the structure makes it di cult to be directly used in electrostatic spinning process (Goh et al 2018). For this reason, additives that can alleviate the hydrogen bonding are needed for the electrostatic spinning of cellulose.…”
