“…also a powerful tool for the preparation of well‐defined polymers with complex topological structures. [ 65‐68 ] Thus, in future research, well‐defined polymers with different topologies might be synthesized through the combination of the Ugi reaction and controlled radical polymerizations (CRPs) and used for protein‐conjugation.…”

Protein modifications | Conjugation | Poly(ethylene glycol) (PEG) | Multicomponent reactions | PolymersRecently, multifunctional polymers for protein conjugation have been facilely synthesized through the multicomponent reactions (MCRs). In this mini-review, current progress in the generation of multifunctional polymers with protein-reactive groups via MCRs is summarized. These multifunctional polymers react with model therapeutic proteins, forming multifunctional polymer-protein conjugates, which are prototypes of sophisticated theranostic agents and antibacterial vaccine candidates. In comparison with the traditional multi-step synthesis, the preparation of multifunctional polymers for protein conjugation through MCRs is straightforward and convenient. Due to these properties, MCRs have the potential to become a new general strategy to achieve polymer-protein conjugates for biological and medical applications.

“…[16] However, there is a strong hydrogen bond interaction between silicon hydroxyl groups on the surface of nanosilica, which makes agglomeration easy and nanodispersion in the polymer matrix difficult. To overcome these deficiencies, the researchers used the approaches of surface pretreatment of fillers, [17] adding dispersants, [18] strong shear, [19] and surface graft polymers [20] to modify them. Among them, surface graft polymers can greatly enhance the interaction between fillers and matrix while also maximizing the reinforcement and toughening effect of nanofillers.…”

Modifying nanoparticles for polymer nanocomposites is important for multifunctional and low-cost developmental direction. However, nanoparticles have several deficiencies, such as dispersion, agglomeration, and poor binding ability with most polymers. This work used soft polyvinyl chloride (PVC with 33.1% plasticizer volume) as the matrix. Polycaprolactone (PCL) was synthesized on the surface of SiO 2 by the bridging effect of silane coupling agent (SiO 2 -PCL), which was expected to improve the bond strength between SiO 2 and soft PVC matrix. Moreover, it enhanced the dispersion of SiO 2 in the PVC matrix. The results revealed that SiO 2 -PCL was nanodispersed in a soft PVC matrix and played a plasticizer role in the composite, which enhanced the tensile strength and elongation at break of PVC composites. The thermal stability and solvent extraction stability of PVC composites elevated with the increase of SiO 2 -PCL content. When the content of SiO 2 -PCL was 8 wt%, the tensile strength (14.54 MPa) and elongation at break (149.47%) of PVC composites were the highest, 64.36% and 60.48% higher than those of unfilled PVC, respectively. It was indicated that PVC composites were dramatically toughened and strengthened by modified SiO 2 , improving their overall performance.
