This mini-review discusses several key transport scenarios in polymer gels, melts and crosslinked polymer networks.

Moreover, we also discuss the ionic conductivity in polymer electrolytes, emphasizing the relationship between ion diffusion and the segmental relaxation of polymers and highlighting current challenges in the community. Finally, potential research directions are suggested concerning how external fields, such as mechanical force fields, active matter and self-propelling particles, affect the particle transport in polymers.

This study explores the incorporation of nanocellulose (NC) derived from cassava peels into polymer electrolyte membranes based on poly(ethylene oxide) (PEO). NC serves as a reinforcing agent, enhancing the mechanical properties of the membranes, such as tensile strength, while its natural abundance and biocompatibility offer a sustainable alternative for electrolyte materials. The membranes were prepared via the solution casting method utilising water as the solvent and subsequently characterised using Fourier transform infrared spectroscopy, XRD, a tensile tester, SEM and TGA/differential thermal analysis/DSC. Incorporating NC into the PEO matrix resulted in enhanced tensile strength and reduced strain at break, while negligibly impacting the ionic conductivity of the membrane. The most effective membrane composition was achieved at a PEO to NC ratio of 80:20, with the optimum ionic conductivity of the polymer electrolyte being 1.54 × 10<sup>−4</sup> S cm<sup>−1</sup>, a tensile strength of 34.87 MPa and an elongation at break of 65.6%.

This study aimed to synthesize a shape memory polyurethane using glycerol as chain extender with a glass transition temperature within a suitable temperature range for biomedical applications. The results showed that the triggering temperatures for the synthesized samples change between 63.95 °C and 88.21 °C. Shape memory properties were investigated for the temperature range 40–75 °C.

Two series of benzoxazines were developed with BBM and HBM using various amines (dodecylamine (dda), octadecylamine (oda), furfurylamine (ffa), aniline (a) and 4-fluoroaniline (fa)) with paraformaldehyde through Mannich condensation with a view to utilize them for anticorrosive and optical resistant coating applications. The molecular structures of the synthesized precursors and benzoxazine monomers were characterized using appropriate analytical techniques. The polymerization temperature of the benzoxazines was assessed using differential scanning calorimetry. Among the benzoxazine monomers synthesized, the monomer HBM-fa exhibits the lowest curing temperature (217 °C). Data obtained from thermogravimetric analysis indicated that the polybenzoxazines poly(BBM-ffa) and poly(HBM-ffa) possess higher thermal stability (455 and 425 °C) and higher char yield (54% and 60%) than the other polybenzoxazines. In both series, octadecylamine-based polybenzoxazines (BBM-oda and HBM-oda) exhibited the highest values of water contact angle of 148° and 149° respectively. Additionally, the benzoxazines showed aggregation-induced emission properties during fluorescence studies. Morphological analyses using different analytical techniques on selected polybenzoxazines were carried out before and after the corrosion process. Results from corrosion studies, i.e. Tafel and Nyquist plots, implied that the polybenzoxazines can be used as effective coating material to protect mild steels from corrosion.

In the present study, we report the modification of guar gum (GG) via polyaddition reaction with toluene diisocyanate (TDI) using dibutyltin dilaurate as catalyst, silicone oil as surfactant and calcium carbonate as filler to form GG-PUF. The as-synthesized GG-PUF was characterized by Fourier transform infrared (FTIR), XRD, field emission SEM, energy-dispersive X-ray spectroscopy, and surface charge analysis. In the FTIR spectrum of GG-PUF, peaks at 3290, 1705, 1595, and 1510 cm<sup>−1</sup> are attributed to stretching vibrations of –NH, –C=O, –C=C– of the benzene ring of TDI, and the –NH bending vibration of the urethane group, respectively. The XRD patterns of GG and GG-PUF indicate their semicrystalline and amorphous nature, respectively. The field emission SEM of GG-PUF exhibits high porosity compared to the smooth surface of GG due to the evolution of CO<sub>2</sub> gas during the foaming reaction. The GG-PUF was evaluated as an adsorbent for cationic dyes from wastewater. The preliminary adsorption studies showed maximum adsorption for malachite green with 93.54% removal at 40 °C and pH 6.0 in 60 min. The adsorption mechanism was studied by various nonlinear kinetic models, namely the pseudo-first order, pseudo-second order and Elovich, and nonlinear isotherm models, such as Langmuir, Freundlich and Temkin. The adsorption followed pseudo-secondorder kinetics and a Langmuir isotherm with a maximum adsorption capacity of 156.44 mg g<sup>−1</sup>. The small value of the error function (<i>χ</i><sup>2</sup>) and normalized standard deviation (Δ<i>q</i>%) from nonlinear models indicated the better fitting of the data into nonlinear kinetics and isotherm models. Furthermore, GG-PUF showed substantial degradability under simulated wastewater conditions at acidic and alkaline pH and reusability up to 10 adsorption–desorption cycles.
