“…The aerogel of the gelatin copolymer was fabricated here as gelatin aerogels are widely reported for their elastoplastic and soft foam properties. 71,72 Pressing Gel-g-P3HT-2 aerogel was expected to induce an enhanced contact between P3HT in Gel-g-P3HT-2 (Figure 7A) and lead to a decrease in the resistance of the aerogel and increase of the current. 73 Indeed, as shown in Figure 7B, as the applied pressure gradually increases from 5 to 20 kPa, ΔI/I 0 increases accordingly.…”

As transient electronics continue to advance, the demand for new materials has given rise to the exploration of conducting polymer (CP)-based electronic materials. The big challenge lies in balancing conductivity while introducing controlled degradable properties into CP-based transient materials. In response to this, we present in this work a concept of using conducting polymers attached to an enzymatically biodegradable biopolymer to create transient polymer electronics materials. Specifically, poly(3hexyl thiophene) (P3HT) is covalently grafted onto biopolymer gelatin, affording graft copolymer gelatin-graf t-poly(3-hexyl thiophene) (termed Gel-g-P3HT). The thin films of Gel-g-P3HT that were produced by optimized processing solvent (THF/H 2 O cosolvent) showed enhanced π−π stacking domains of P3HT, resulting in semiconducting thin films with good electroactivity. Due to the presence of amide bonds in the gelatin backbone, Gel-g-P3HT underwent degradation over a period of 5 days, resulting in the formation of amphiphilic micellar nanoparticles that are biocompatible and nontoxic. The potential of these conductive and degradable graft copolymers was demonstrated in a pressure sensor. This research paves the way for developing biocompatible and enzymatically degradable polymer materials based on P3HT, enabling the next generation of transient polymer electronics for diverse applications, such as skin, implantable, and environmental electronics.

“…Common functional groups contain carboxyl, amino, hydroxyl and so on. Heavy metal ions can form coordination bonds with the above groups, or form cage structures to reduce their concentration [28,29]. In recent years, the adsorption of heavy metal ions by magnetic nanomaterials and natural polymer materials as adsorbents has attracted extensive attention from researchers.…”

Heavy metal ion wastewater is very harmful to human body and environment, and the adsorption materials used in traditional adsorption methods such as starch cellulose are easily hydrolyzed, resulting in secondary pollution to water. In this paper, acrylic polymers such as polyacrylate /polyglycidyl methacrylate/polyhydroxyethyl methacrylate were grafted onto magnetic starch by grafting polymerization to improve the hydrolysis and adsorption properties of starch. Acrylic polymers modified magnetic starch materials St/Fe3O4-g-pAA, St/Fe3O4-g-pHEMA and St/Fe3O4-g-pGMA were prepared, and their properties as adsorbents for Cu(II) removal were studied. The adsorption experiment results show that St/Fe3O4-g-pAA has the best adsorption performance under the same adsorption conditions. The maximum unit adsorption capacity of St/Fe3O4-g-pAA was 78.1 mg/g under the optimum adsorption conditions of 20 mg/L initial concentration of copper ion solution, pH value of solution 7 and adsorption time 160 min. St/Fe3O4-g-pGMA has the best stability and the best reproducibility and can retain 95.7% of the first adsorption effect after 8 adsorption cycles. The adsorption properties of St/Fe3O4-g-pHEMA are the least dependent on pH value. The adsorption processes of the three acrylic polymers modified magnetic starch adsorption materials all follow the Langmuir isotherm model, which is more consistent with the second-order II kinetic model, indicating that the three acrylic polymers modified magnetic starch adsorption materials are mainly chemisorbed and occur on the single molecular layer. The thermodynamics of adsorption process was studied and the data show that adsorption process belongs to endothermic reaction and temperature rise was conducive to adsorption.
