Special Issue Information

Dear Colleagues,

The present Special Issue is a continuation of previous successful Special Issue, titled “Advance in Nanostructured Polymers” (https://www.mdpi.com/journal/nanomaterials/special_issues/nanostructured_polymers), which was also hosted by this Guest Editor.

Nanostructured polymers are a remarkably interesting class of materials suitable for an incredibly diverse range of applications depending on the polymers used, and whether they are doped, and on the solvents used in the fabrication process. Nanostructured polymers are certainly a unique class of materials that can take on different functional forms.

Polymers today may be considered to be structural or functional, and are often most interesting when they form nanostructured composites. They may often require simple or low-cost processing steps, and this can make them particularly attractive. Examples range from solvent cast, and electrospun nanofiber membranes through to aerogels. Polymers may be water- or solvent-soluble, and a range of additives can be introduced, such as nanoparticles, carbon nanotubes, graphene, graphene oxide (GO), reduced GO, etc., to functionalise them. Formed polymers may take different physical forms and require post-fabrication processing steps, for example, to add electrodes in functional systems.

This Special Issue aims to address the latest research devoted to exploring the potential to develop new and novel nanostructured polymers, to explore the materials processing required and the methods used to evaluate their intrinsic characteristics, as well as to analyse their functionality for a diverse range of applications. Research articles focusing on the development of novel biocompatible nanostructured polymers that can be applied in environmental, health, and life sciences and bioinspired soft robotics are especially welcome. Nanostructured polymers that can be developed for larger-scale applications are strongly encouraged.

To improve the water absorbency and water-retention rate of superabsorbent materials, a porous calcium carbonate composite superabsorbent polymer (PCC/PAA) was prepared by copolymerization of acrylic acid and porous calcium carbonate prepared from ground calcium carbonate. The results showed that the binding energies of C–O and C=O in the O 1s profile of PCC/PAA had 0.2 eV and 0.1–0.7 eV redshifts, respectively, and the bonding of –COO groups on the surface of the porous calcium carbonate led to an increase in the binding energy of O 1s. Furthermore, the porous calcium carbonate chelates with the –COO group in acrylic acid through the surface Ca2+ site to form multidirectional crosslinking points, which would increase the flexibility of the crosslinking network and promote the formation of pores inside the PCC/PAA to improve the water storage space. The water absorbency of PCC/PAA with 2 wt% porous calcium carbonate in deionized water and 0.9 wt% NaCl water solution increased from 540 g/g and 60 g/g to 935 g/g and 80 g/g, respectively. In addition, since the chemical crosslinker N,N′-methylene bisacrylamide is used in the polymerization process of PCC/PAA, N,N′-methylene bisacrylamide and porous calcium carbonate enhance the stability of the PCC/PAA crosslinking network by double-crosslinking with a polyacrylic acid chain, resulting in the crosslinking network of PCC/PAA not being destroyed after water absorption saturation. Therefore, PCC/PAA with 2 wt% porous calcium carbonate improved the water-retention rate by 244% after 5 h at 60 °C, and the compressive strength was approximately five-times that of the superabsorbent without porous calcium carbonate.

Strain sensors based on conducting polymer hydrogels are considered highly promising candidates for wearable electronic devices. However, existing conducting polymer hydrogels are susceptible to aging, damage, and failure, which can greatly deteriorate the sensing performance of strain sensors based on these substances and the accuracy of data collection under large deformation. Developing conductive polymer hydrogels with concurrent high sensing performance and self-healing capability is a critical yet challenging task to improve the stability and lifetime of strain sensors. Herein, we design a self-healable conducting polymer hydrogel by compositing poly(3,4-ethylenedioxythiophene):polystyrene sulfonate (PEDOT:PSS) nanofibers and poly(vinyl alcohol) (PVA) via both physical and chemical crosslinking. This PEDOT:PSS-PVA nanocomposite hydrogel strain sensor displays an excellent strain monitoring range (>200%), low hysteresis (<1.6%), a high gauge factor (GF = 3.18), and outstanding self-healing efficiency (>83.5%). Electronic skins based on such hydrogel strain sensors can perform the accurate monitoring of various physiological signals, including swallowing, finger bending, and knee bending. This work presents a novel conducting polymer hydrogel strain sensor demonstrating both high sensing performance and self-healability, which can satisfy broad application scenarios, such as wearable electronics, health monitoring, etc. Full article
