Description
<p>A lot of nanocomposites containing C<sub>60</sub> have been developed to enable various application opportunities. However, it seems impossible to incorporate C<sub>60</sub> into ceramics without destroying the C<sub>60</sub> molecules, because ceramics are typically sintered at high temperatures that could result in the chemical reaction of C<sub>60</sub>. Herein, we report the successful integration of C<sub>60</sub> with ZnO using cold sintering process. (1-x)ZnO-xC<sub>60</sub> composites with x ranging from 0 to 5 wt% are densified into monolithic structures with relative densities over 95%. Clear C<sub>60</sub> molecules are observed in the cold sintered composites, and thin C<sub>60</sub> layers with less than 10 nm are located at the ZnO grain boundaries. With C<sub>60</sub> altering the interfacial structures of ZnO ceramics, the electrical properties are improved significantly, especially, the breakdown electric field at 1 mA cm<sup>−2</sup> is enhanced from ∼80 V mm<sup>−1</sup> to ∼2100 V mm<sup>−1</sup>. The FEM analysis indicates that the current density at the interfaces of ZnO and C<sub>60</sub> is higher than other regions. This work thus indicates that cold sintering process provides a promising pathway to design new types of functional materials through the integration of C<sub>60</sub> and ceramics.</p>
