“…The structural and mechanical data were derived from the electrospun PAN and PAN/HNT fibrous meshes which we have prepared in our laboratories. A detailed account of the preparation of the solutions of PAN and PAN/HNT used in the electrospinning process have been reported in the research data article [1] . The research data article [1] also contained a detailed account of the process of electrospinning the PAN and PAN/HNT fibrous meshes.…”

“…The data for the cross-sectional area ( A ) of each specimen, which was used in the calculation for the nominal stress generated in the mesh, involved measuring the thickness and width at the mid-substance (between the grips) of each specimen under an inverted optical microscope, prior to mechanical testing. A setup of the micromechanical tester under the inverted optical microscope has been illustrated in the research article [1] . The data derived from hydrated PAN and PAN/HNT fibrous mesh involved submerging the respective individual specimens in water (held in a pedri dish) during the test.…”

“…With regards to the data on SEM images showing the fractured morphology of the specimens, our observation of the fractured specimens, based on a qualitative examination, revealed that the fracture morphology from SEM images was not appreciably different from that of the morphology of pristine specimens. Thus, we have not included the data with the manuscript because (1) this does not add anything new to the work [1] which preceded this paper and (2) no quantitative assessment was carried out to assess the true extent of the similarities between the morphology of the pristine and the fractured specimen.…”

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).

Halloysite nanotubes (HNT) and carbon nanotubes (CNT) are potential nanoparticles that can be incorporated into polymer adhesives to enhance their performance for repairing damaged composite structures. However, the nanoparticle adhesive blends need to be assessed as their performance may be affected by the preparation techniques, nanoparticles types, and mass concentration. The present study aimed to evaluate the mechanical properties (specifically tensile and adhesion properties), physical properties (including wetting and rheological characteristics), thermal properties, and chemical properties of two commercially available adhesives, namely Epo‐Tek 301 (consists of bisphenol A diglycidyl ether resin, known as DGEBA) and Nano‐Force E100 (consists of bisphenol A/F epichlorohydrin premixed with CNTs). Furthermore, DGEBA adhesive with 1, 3, 5, and 9 wt% HNTs, and DGEBA adhesive with 1 wt% of treated and untreated CNTs were prepared. The findings revealed that there were no appreciable differences in the mechanical, physical, thermal, and chemical properties between the neat DGEBA and DGEBA with 1 wt% HNTs. However, the mechanical and physical properties deteriorated, and the char yield increased after thermal degradation for adhesives containing more than 1 wt% HNTs. On the other hand, no enhancement in all properties was observed for adhesives containing CNTs. Moreover, the adhesives containing CNTs exhibited higher viscosity than Nano‐Force E100, which could hinder resin infiltration for composite repair applications. Therefore, the types of adhesive to be used for repairing impact‐damaged composite structures must be prudently selected.

The primary objective of this research is to fabricate semi‐interpenetrating polymer networks (semi‐IPNs) via in‐situ polymerization of methyl methacrylate (MMA) within a polyurethane (PU) framework. To produce polymethyl methacrylate (PMMA) from MMA in the PU matrix, solution polymerization was utilized in the following weight ratios: 30/70, 50/50, 70/30, and 90/10. The effective formation of semi‐IPNs of PU/PMMA was confirmed by several techniques. Fourier transform infrared (FTIR) proves that no new chemical bonds formed between the semi‐IPNs, and only physical interactions were present, and X‐ray diffraction (XRD) techniques tell about the amorphous nature of these semi‐IPNs. The field emission scanning electron microscope (FESEM) and atomic force microscope (AFM) were utilized to examine the morphology of PU/PMMA semi‐IPNs. In contrast to alternative semi‐IPNs, 70/30 and 90/10 PU/PMMA exhibit a uniform morphology devoid of phase separation. Furthermore, the significant thermal stability and transitions of these semi‐IPNs were assessed using a thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). Additionally, the mechanical analysis indicates that among the different percentages of PU/PMMA, 70/30 PU/PMMA exhibits the highest tensile strength of approximately 50.5 MPa. The observed enhancement in mechanical strength can be attributed to interpenetrating networks (IPNs) formed between the constituents. The synthesized PU/PMMA semi‐IPNs have potential in various fields, including medical devices, automotive components, sports, and other advanced applications.
