Recent Advances in Polymer Nanocomposites: Unveiling the Frontier of Shape Memory and Self-Healing Properties—A Comprehensive Review

Molecules, Journal Year: 2024, Volume and Issue: 29(6), P. 1267 - 1267

Published: March 13, 2024

Shape memory and self-healing polymer nanocomposites have attracted considerable attention due to their modifiable properties promising applications. The incorporation of nanomaterials (polypyrrole, carboxyl methyl cellulose, carbon nanotubes, titania graphene, graphene oxide, mesoporous silica) into these polymers has significantly enhanced performance, opening up new avenues for diverse capability in depends on several factors, including heat, quadruple hydrogen bonding, π–π stacking, Diels–Alder reactions, metal–ligand coordination, which collectively govern the interactions within composite materials. Among possible interactions, only bonding between constituents been shown be effective facilitating at approximately room temperature. Conversely, thermo-responsive shape require elevated temperatures initiate healing recovery processes. Thermo-responsive (TRSMPs), light-actuated, magnetically actuated, Electrically actuated Memory Polymer Nanocomposite are discussed. This paper provides a comprehensive overview different types involved SMP SHP examines behavior both temperature conditions, along with biomedical many applications SMPs, special given (drug delivery, orthodontics, tissue engineering, orthopedics, endovascular surgery), aerospace (hinges, space deployable structures, morphing aircrafts), textile (breathable fabrics, reinforced electromagnetic interference shielding fabrics), sensor, electrical (triboelectric nanogenerators, information energy storage devices), electronic, paint coating, construction material (polymer cement composites)

Conducting polymer hydrogels based on supramolecular strategies for wearable sensors

Exploration, Journal Year: 2024, Volume and Issue: 4(5)

Published: March 14, 2024

Abstract Conductive polymer hydrogels (CPHs) are gaining considerable attention in developing wearable electronics due to their unique combination of high conductivity and softness. However, the absence interactions, incompatibility between hydrophobic conductive polymers (CPs) hydrophilic networks gives rise inadequate bonding CPs hydrogel matrices, thereby significantly impairing mechanical electrical properties CPHs constraining utility electronic sensors. Therefore, endow with good performance, it is necessary ensure a stable robust network CPs. Encouragingly, recent research has demonstrated that incorporating supramolecular interactions into enhances interaction, improving overall CPH performance. comprehensive review focusing on (SCPH) for sensing applications currently lacking. This provides summary typical strategies employed development high‐performance elucidates SCPHs closely associated Moreover, discusses fabrication methods classification SCPH sensors, while also exploring latest application scenarios Finally, challenges sensors offers suggestions future advancements.

Advances in amelioration of plasma electrolytic oxidation coatings on biodegradable magnesium and alloys

Heliyon, Journal Year: 2024, Volume and Issue: 10(4), P. e24348 - e24348

Published: Jan. 11, 2024

Magnesium and its alloys are considered excellent materials for biodegradable implants because of their good biocompatibility biodegradability as well mechanical properties. However, the rapid degradation rate severely limits clinical applications. Plasma electrolytic oxidation (PEO), also known micro-arc (MAO), is an effective surface modification technique. there many pores cracks on coating under conventional PEO process. The corrosive products tend to penetrate deeply into substrate, reducing corrosion resistance biocompatibility, which makes PEO-coated Mg difficult meet long-term needs in vivo implants. Hence, it necessary modify coating. This review discusses formation mechanism influential parameters coatings Mg. followed by a latest research pretreatment typical amelioration past 5 years, including calcium phosphate (Ca–P) coating, layered double hydroxide (LDH)-PEO ZrO2 incorporated-PEO antibacterial ingredients-PEO drug-PEO polymer-PEO composite fluorination (PEF) self-healing Meanwhile, improvements morphology, resistance, wear abilities, drug loading abilities preparation methods modified discussed well.
