Resistance to aggregation-caused quenching: chitosan-based solid carbon dots for white light-emitting diode and 3D printing

The Studies on Chitosan for Sustainable Development: A Bibliometric Analysis

“…Li et al [ 82 ] performed a review on the use of chitosan in electronic devices such as solar cells, organic field-effect transistors, and light-emitting diodes (LED). In addition, chitosan-based solid carbon dots can also be used for white LED and 3D printing [ 83 ]. Chitosan-mediated LED illumination also has better antibacterial treatment on Escherichia coli , Listeria monocytogenes , and Salmonella spp.…”

Progress of layered double hydroxide-based materials for supercapacitors

“…Due to the unique layer structure of LDHs, the composition and ratio of their metal cations can be adjusted, the type and number of interlayer anions can be controlled, and the number of layers and layer spacing can be easily changed, making them easy to be compounded with other materials to realize functionalization, etc. [97][98][99] Pristine LDHs are also considered superior supercapacitor electrodes, thanks to their layered structure and adjustable interlayer spacing, providing large specific surface area and adequate ion transport rates. [101][102][103] However, pristine LDHs suffer from severe refilling, which can reduce their overall exposed surface area and make electrolyte ion transport difficult.…”

pH-Responsive Intelligent Antibacterial Coatings Based on 2D-COF for Controlled Release of Capsaicin

“…At present, the main methods of intelligently controlling the release of antifouling agents are pH response, enzyme response, and temperature response . Up to now, a variety of nanomaterials with good controlled-release properties have been reported, including poly­(vinyl alcohol) microspheres in a silk sericin-based hydrogel, composite films with an adjustable number of layers using sodium alginate (SA), chitosan (CS), and activated charcoal (AC), microcrystals, polyvinyl alcohol/chitosan microspheres, and a selenium-rich tea set. , Chitosan (CS) has antibacterial properties due to the interaction between its positively charged amino group and the negatively charged cell membrane of bacteria. , The nanocapsules made from CS exhibit typical pH response characteristics due to the large number of amino groups contained in the side chain. , In addition, the intelligent delivery of fungicides can be realized by the modification of chitosan. , Our research group has developed a capsaicin@chitosan (CAP@CS) microcapsule with pH response performance, which can realize the intelligent controlled release of the natural bactericide CAP, which plays an effective sterilization and antifouling role. , However, its dispersion is limited. In order to improve the dispersion on the basis of pH response sterilization, we hope to introduce other materials to further improve the performance of intelligent response controlled release sterilization. , Two-dimensional materials (graphene, covalent organic frameworks) have great potential for marine protective materials, such as corrosion protection and fouling protection, due to their excellent adsorption characteristics, mechanical strength, thermal stability, and other characteristics. , In recent years, 2D covalent organic frameworks (COFs), which are typical representatives of 2D nanomaterials, have the characteristics of diverse synthesis methods, large specific surface area, stable physical and chemical properties, and broad application prospects in different fields. , COF-MOF hybrid materials have ingenious and obvious structural characteristics and excellent performance .…”
