Nanofiber networks comprising polymer-metal core–shell structures exhibit several advantages, such as high uniformities and considerable flexibilities. Additionally, the flexibility of the nanofiber network may be further enhanced by engineering the network topology. Therefore, in this study, the topologies of polyvinylidene fluoride (PVDF)-Pt core–shell nanofiber (CS NF) networks were engineered, and their performances as flexible transparent electrodes were comprehensively evaluated. Three distinct topologies of nanofiber networks were induced using circular, square, and rectangular electrode collectors. A highly uniform nanofiber network was obtained using the square electrode collector, which generated a high density of nanofiber junctions (nodes). Consequently, this nanofiber network exhibited the smallest sheet resistance $$\left({R}_{\mathrm{s}}\right)$$ R s and lowest optical transmittance $$\left(T\right)$$ T among the three CS NF networks. In contrast, nanofiber bundles were frequently formed in the randomly aligned CS NF network prepared using the circular electrode collector, reducing the node density. As a result, it simultaneously exhibited a very small $${R}_{\mathrm{s}}$$ R s and high $$T$$ T , generating the largest percolation figure of merit $$\left(\Pi =330.5\right)$$ Π = 330.5 . Under certain strain directions, the CS NF network with the engineered topology exhibited a significantly enhanced mechanical durability. Finally, a flexible piezoelectric pressure sensor with CS NF network electrodes was fabricated and its sensing performance was excellent.

“…Psyllium husk is the main source of arabinoxylan (Li, Q., Wang, S., Jin, X., Huang, C., & Xiang, Z., 2020) and is of laxative nature so used for the treatment of constipation and diarrhoea due to its water-solubility and gel-forming capacity. Psyllium-based polymeric materials and hydrogels have been reported for various therapeutic and pharmaceutical applications like cholesterol reduction (Uehleke, B., Ortiz, M., & Stange, R., 2008), wound dressing (Ahmad, N., et al , 2021), drug delivery (Singh, B., Sharma, et al, 2022, Kotta, S., et al,2022 tissue regeneration (Poddar, S., et al, 2021), cancer treatment (Kumar, D., Gautam, A., & Kundu, P. P., 2022, Masood, R., & Miraftab, M., 2010) lower normal LDL level (Jovanovski, E., et al, 2018, Everson, G. T., et al, 1992 and Industrial applications like treating of coloured effluents from water (Druzian, S. P., 2021), wastewater treatment (Das, N., Ojha, N., & Mandal, S. K., 2021, Singh, J., Kumar, S., & Sharma, S. 2022) such as removal of Hg(II) from the solution (Kumar, D., Pandey, J., Khan, N., Kumar, P., & Kundu, P. P. 2019) to mention a few. The hydrophilic nature of the psyllium husk imparting its excellent swell ability is one of the defining properties for its varied applications (Singh, B., Chauhan, G. S., Bhatt, S. S., & Kumar, K. (2006), Singh, B., Sharma, N., & Chauhan, N. (2007, Singh, B., & Chauhan, N., 2009).…”

Natural polysaccharides are being explored as the matrices for attaining speciality materials for pharmaceutical, medicinal and environmental applications via chemical modification such as grafting. Psyllium polysaccharide-based hydrogels and nanogels have potential biomedical and water purification applications due to their advantageous properties such as stimulus responsiveness, biocompatibility, target drug delivery and stability. The present study aims to synthesise hydrogel and nanogels of psyllium and attain comparative data for the two to undermine their potential applications. Psyllium– cl –N,N–MBAm–poly(AAm) hydrogel (Psy-MBAm-AAm – hg) and Psyllium– cl –N,N–MBAm–poly(AAm) nanogel (Psy-MBAm-AAm – ng) were synthesised by grafting acrylamide (AAm) onto psyllium using ammonium persulphate (APS) as a free radical initiator in a redox system where N, N-methylene bisacrylamide acted as a crosslinker. The comparative study of synthesised gels was carried out by studying swelling characteristics at acidic and basic pH (7 and 4) and at varied temperatures for both matrices. The synthesised hydrogel and nanogels were subjected to characterisation by Fourier transform infrared spectroscopy (FTIR), Field Emission Scanning Electron Microscopy (FESEM), and Zeta Potential Analysis to get evidence for successful synthesis and nanogel formation.
