Ti₃C₂Tₓ MXene–Silk Fibroin Composites: Tuning Electrical Conductivity and THz Performance

We extend our gratitude to our collaborators for their recent publication in Graphene and 2D Nanomaterials, highlighting innovative work on MXene–silk fibroin composite films.

This research explores the development of materials with tailorable electronic and thermal properties, focusing on Ti₃C₂Tₓ MXenes integrated into silk fibroin films.

The study demonstrates that while the inclusion of silk fibroin reduces direct current (DC) conductivity by several orders of magnitude, the alternating current (AC) conductivity in the terahertz (THz) range and electromagnetic interference (EMI) shielding remain largely intact.

Using time-resolved THz spectroscopy, the researchers revealed that silk encapsulation not only preserves high-frequency performance but also enhances thermal recovery after optical excitation.

These results confirm that the electrical and thermal response of MXene–silk composites can be finely tuned by adjusting silk content, offering a pathway toward biocompatible and customizable electronic materials for flexible and wearable applications.
