Then, we synthesized a chitosan-based macromolecular antioxidant with long-chain alkene, aromatic secondary amine, and thioether groups (COS-UC-MC-MPA) by sequentially grafting functional compounds 10-undecanonyl chloride (UC) and antioxidant MC-MPA onto natural macromolecular polymer chitosan (COS). The free radical scavenging ability of COS-UC-MC-MPA was assessed by using 2,2-Diphenyl-1-picrylhydrazyl (DPPH), and the results demonstrated that COS-OC-MC-MPA has high scavenging rate of 76.5 % for DPPH free radicals after 1 min of contact with DPPH dimethyl sulfoxide solution, showing excellent free radical scavenging ability. In addition, the results of accelerated thermo-oxidative aging test, thermogravimetric (TG) test, kinetic analysis of thermal-oxidative degradation, extraction resistance test, and volatilization resistance test indicated that COS-UC-MC-MPA with superior migration resistance and volatilization resistance could effectively enhance the antioxidative properties, thermal stability and thermal-oxidative stability of rubber composites. Moreover, the results of rubber processibility analysis (RPA) test and scanning electron microscopy (SEM) implied that the addition of COS-UC-MC-MPA is also conductive to improving the dispersibility of silica in rubber matrix.

Incorporating 10 wt% of g-C<sub>3</sub>N<sub>4</sub> nanosheets to PEDOT:PSS improved the Seebeck coefficient to 74.3 μVK<sup>−1</sup>, ∼5 times higher than the PEDOT:PSS film. However, this led to a decrease in electrical conductivity, limiting the power factor to 335.4 μWm<sup>−1</sup>K<sup>−2</sup>. In order to address this, CNTs were added as conductive fillers. The resulting PEDOT:PSS composite, with 10 wt% of g-C<sub>3</sub>N<sub>4</sub> and 10 wt% CNTs, showed a significant power factor of 589.8 μWm<sup>−1</sup>K<sup>−2</sup>, an electrical conductivity of 810.6 Scm<sup>−1</sup>, and a Seebeck coefficient of 84.5 μVK<sup>−1</sup>, indicating a substantial improvement in the thermoelectric performance of pristine PEDOT:PSS. The increased Seebeck coefficient in the PEDOT:PSS and g-C<sub>3</sub>N<sub>4</sub> composite is due to reduced carrier concentration and energy filtering at the interfaces.

Recently, researchers have designed a smart upconversion nanoparticles (UCNPs) that have unique characteristics to achieve targeting for respond tumor microenvironment.
