Special Issue Information

Dear Colleagues, 

In recent years, multifunctional polymer nanocomposites have attracted interest due to their advanced properties, such as unique structural and physical characteristics. Furthermore, the surface of monomers/polymers can be easily functionalized by either tuning their polymerization techniques or cross-linking sites, according to the desired application type. In another approach, polymers with inorganic nano-fillers such as carbon nanomaterials, TiO2, and MoS2 and so on have assisted the fabrication of high-performance multifunctional polymer nanocomposites. These synthesis approaches have been used for the development of new cutting-edge materials for environmental remediation to bioelectronics.  

Therefore, a knowledge-based synergistic development of the structure-property relationship of functionalized polymer composites needs to be addressed in detail. This relationship is important to know the role of each precursor material for the development of the composite and its effect on the corresponding application.  Also, the stability of functionalized polymers or leaching of nanomaterials should be another useful parameter to determine whether these materials are being used as point-of-use device applications or not. 

This special issue will highlight original articles and reviews on the synthesis and characterization of functionalized polymer composites for various advanced applications. Submissions highlighting functionalized biopolymers, waste materials, and metal-organic frameworks for energy and environmental science are highly encouraged.

Abstract
Due to unique chelating and macrocyclic effects, crown ether compounds exhibit wide application prospects. They could be introduced into amphiphilic copolymers to provide new trigger mode for drug delivery.

Due to unique chelating and macrocyclic effects, crown ether compounds exhibit wide application prospects. They could be introduced into amphiphilic copolymers to provide new trigger mode for drug delivery. In this work, new amphiphilic random polymers of poly(lipoic acid-methacrylate-co-poly(ethylene glycol) methyl ether methacrylate-co-N-isopropylacrylamide-co-benzo-18-crown-6-methacrylamide (abbrev. PLENB) containing a crown ether ring and disulphide bond were synthesized via RAFT polymerization. Using the solvent evaporation method, the PLENB micelles were formed and then used to load substances, such as doxorubicin hydrochloride (DOX) and gold nanoparticles. The results showed that PLENB exhibited a variety of lowest critical solution temperature (LCST) in response to the presence of different ions, such as K+, Na+ and Mg2+. In particular, the addition of 150 mM K+ increased the LCST of PLENB from 31 to 37 °C and induced the release of DOX from the PLENB@DOX assemblies with a release rate of 99.84% within 12 h under 37 °C. However, Na+ and Mg2+ ions could not initiate the same response. Furthermore, K+ ions drove the disassembly of gold aggregates from the PLENB-SH@Au assemblies to achieve the transport of Au NPs, which is helpful to construct a K+-triggered carrier system.
