Abstract Flexible shape memory polyurethanes (SMPUs) are the favorable candidates as a coating or substrate for wearable smart textiles, electronics, and biomedical applications. However, conventional SMPUs (e.g., 1,4 butanediol (BDO)‐based) not suitable in these applications due to high rigidity, poor mechanical properties, low recovery, transition temperature. Herein, polyethylenimine (PEI)‐based SMPU with temperature tailored properties reported. The synthesized characterized, their...
Abstract Shape memory polymers are remarkable materials renowned for their distinctive ability to fix and recover original shape in response specific stimuli. However, the lower fixity (SF) of conventional thermally triggered polyurethane (SMPU) has limited its broad application potential. This study investigates transformative influence graphene oxide (GO) nanofillers when incorporated into a linear diisocyanate‐based mixing segment SMPU (SMPU‐GO). The SF issue is ingeniously addressed by...
The present article highlights a novel approach towards investigating the memory behaviour of shape filaments integrated into knitted textile structure. This study is first step to investigate interaction such smart materials within structures. integration can further open vast possibilities in designing textiles with unique functionalities as sensing and actuating. A fabric (SMF) was successfully using filament polyester yarn. systematic investigation carried out quantify SMF by...
In December of 2019, the first outbreak COVID-19 was detected in mainland China, eventually spreading to every continent world except Antarctica. Named Coronavirus Disease 19 (COVID-19) by World Health Organization (WHO), this highly contagious disease caused virus SARS-CoV-2. With a transmission rate greater than SARS or common flu, continued tremendous efforts will be needed successfully combat disease. article, we review role that data science is playing war. Data science, combined with...
Mechanical robustness and flexibility of shape memory polyurethane (SMPU) make them a prominent candidate in various field. However, the characteristics are hampered due to lower breaking stress strain originating from slippage hard segments during deformation entropic elasticity segments. Herein, SMPU is synthesised by modification Polycaprolactone diol (PCL) based soft segment introducing linear chain diisocyante, that hexamethylene diisocyanate (HDI) as mixing rigid MDI (4,4′-methylene...
Front Cover: In article number 2000215 by Bijay P. Tripathi, Bipin Kumar, and co-workers, a highly flexible, robust thermoresponsive shape memory polyurethane crosslinked polyethylenimine is synthesized, which shows excellent reproducible performance at body temperature, aided reversible physical crosslinks. These advantages can have significant implications in biomedical, smart wearable, flexible electronic applications.
Abstract Nano‐multilayers of Cu(6 nm)/Co(∼22 nm) have been electrodeposited in potentiostatic pulse mode on ITO coated glass substrates. Cyclic voltammetry and chronoamperometric studies were performed to determine the potential duration for deposition individual layers. A 50‐bilayer stack exhibited a room temperature GMR 12.5%, at 8 kOe. Even low fields ∼3 kOe, this multilayer ∼10% GMR, thereby demonstrating application electrodeposition (ED) process achieving appreciable value lower field...
Co/Cu multilayers were electrodeposited in potentiostatic mode, using two different sulphate baths, one without any additive and other containing trisodium citrate. Deposition parameters, like deposition potential time, established for both the baths by carrying out a series of cyclic voltammetry chronoamperometric experiments. Thin films, having 2–20 bilayers, under parameters. It was observed that films deposited from bath citrate comparatively much smoother than free bath. The with 20...
Layered transition metal selenides have garnered widespread attention as the potential non-noble metal-based materials to cater diverse energy conversion and storage aspects. Therefore, we implemented an integrated experimental theoretical methodology explore application of molybdenum diselenide (MoSe2) for HER, OER, supercapacitor avenues via employing nanostructural surface engineering performance enhancement strategy. Herein, demonstrated successful execution a laboratory-scale...
