Abstract:
Recent advances in nanotechnology of two-dimensional (2D) layered materials combined with parallel improvements in biotechnology and synthetic biology demonstrated that more complex composites materials with properties engineered precisely to optimize performance could be achieved. We propose to create functional programmable materials with user defined physical properties from composites of 2D-layered materials and polymeric proteins. Our approach is based on an ultra-fast microscopy technique to screen molecular morphology of polymeric proteins. These proteins have several advantages as programmable materials: (i) their chain length, sequence, and stereochemistry can be easily controlled, (ii) their molecular structure and morphology is well-defined, (iii) they provide a variety of functional chemistries for conjugation to 2D materials, and (iv) they can be designed to exhibit a variety of physical properties.

The variability of the amino-acid sequences in the polymeric proteins, which will dictate the degree of crystallinity and alignment of the protein layers, are used to control the interactions at the 2D material/protein interface, ultimately dictating the functional physical properties (e.g., electrical resistivity and thermal conductivity) of novel materials and devices.
