LAYER-BY-LAYER FILMS AND COATINGS CONTAINING MXENES

Overview

MXenes are two dimensional nanosheets containing transition metal carbides and/or nitrides having many desirable properties like graphene sheets. However, coatings that take advantage of MXenes and their properties have not yet been demonstrated. Flexible and wearable electronics require coatings with high electrical conductivity while performing under extreme mechanical bending and/or stretching conditions. The current inventive approach offers a new line of coatings based on MXenes especially for use with flexible electronics.

Technology

The layer-by-layer assembled composition consists of alternating layers of a cationic polymer layer and a negatively charged MXene layer. The LbL approach is versatile to a variety of surfaces, substrates, and geometries (Figure 1). For example, metal, glass, ITO-coated glass, plastic, gold-coated plastic, silicon wafer, and fabric are used as substrates, and many others are possible. The MXene-based layer-by-layer films or coatings exhibit enhanced properties, such as improved mechanical integrity, mechanical flexibility, enhanced electronic, and/or other useful features.
