Peptide-Based Gel in Environmental Remediation: Removal of Toxic Organic Dyes and Hazardous Pb2+ and Cd2+ Ions from Wastewater and Oil Spill Recovery

“…Hydrogels can also be very usefulmaterialsin many other fields apart from the abovementionedapplications. [82][83][84][85][86][87][88] On the other hand, xerogels (dried gels) can be used in various fields, such as energy-storage devices, metacomposites, electromagnetic wave absorbing/shielding devices, and others. [89][90][91][92] Xerogels having π-surfaces can perform similar water remediation and hence these materials can be used as an attractive candidate for waste water management.…”

“…Some absorbents regularly used are carbon-based materials, polymers, clay minerals, and others. − There are some materials and methods which are very effective toward oil spill and metal ion adsorption. − In this context, it is notable that hydrogels, because of their interstitial void spaces, can absorb dyes and heavy metal ions. Hydrogels can also be very useful materials in many other fields apart from above mentioned applications. − On the other hand, xerogels (dried gels) can be used in various fields, such as energy-storage devices, metacomposites, electromagnetic wave absorbing/shielding devices, and others. − Xerogels having π-surfaces can perform similar water remediation, and hence these materials can be used as an attractive candidate for wastewater management …”

Mussel-Inspired Conductive Hydrogel with Self-Healing, Adhesive, and Antibacterial Properties for Wearable Monitoring

“…Wearable electronic sensors possess excellent electrical conductivity to convert human physiological activities into electrical signals to better monitor human motion. Owing to their unique performance, wearable electronic devices have been extensively studied in the fields of biomedicine, artificial electronic skin, soft robotics, and health-recording electrodes. , Hydrogels have a three-dimensional (3D) network structure formed by physical or chemical cross-linking between molecular chains. , Although hydrogels have stable 3D structures that give them solid-like properties, they contain ample water that can diffuse through them, thereby imparting them liquid-like properties. , As a kind of soft wet material, hydrogels with healing and conductive properties and unique structural properties make them extremely similar to biological tissues. , Because of their similarity to tissues, biocompatibility, , and flexibility, conductive hydrogels have been widely used in biological fields involving electronic skin, , wearable electronic sensing, − controlled drug delivery, , and tissue engineering. − Generally, electronic conductive hydrogels can be constructed by using polymers such as polyaniline , and polypyrrole , and fillers such as metal particles, graphene oxide, and carbon nanotubes, which are mainly based on hydrogen bonding, π–π conjugation, metal effects, or electrostatic interactions .

Preparation and characterization of an electromagnetic composite polypyrrole/polyethylene short filament geotextile

“…Polyacetylene is the earliest synthesized conductive polymer material, but its service life is short; polythiophene and its derivatives have excellent environmental stability and good mechanical strength, but the conductivity is weak; polyaniline is inexpensive, easy to obtain, with good electrical conductivity and electromagnetic microwave absorption property, but compared with polypyrrole, polyaniline is not easy to control in experimental operation, and easily causes agglomeration. 11,12 Polypyrrole conductive polymer is a common raw material with good stability, a simple synthesis process, and high conductivity. 13,14 It is widely used in the preparation of ultra-capacitive and antistatic materials, battery electrode materials, electromagnetic protection materials, electrocatalytic materials, metal corrosion protection materials, ion adsorption materials, etc.. 15 Polypyrrole noumenon has poor conductivity and doping is required to obtain polypyrrole with higher conductivity.…”
