Abstract

Nanodiamond Functionalization Interphase Surface chemistry Mechanical properties Polymer nanocomposites Dispersion
Due to their versatile properties combined with a favorable strength-to-weight ratio, polymer composites find numerous applications in industry. To further improve their performance, new matrix and reinforcing materials are required. Nanocomposites, containing fillers with particle sizes smaller than 100 nm, hold a great potential to fulfill this demand. At these small length scales, the specific surface area becomes large and polymer–filler interactions, leading to the formation of an interphase with improved properties, can dominate the properties of the composite. Tailoring the properties of the interphase allows for creating new nanocomposite materials. The small size of detonation nanodiamond particles in combination with their superior mechanical properties (diamond properties) and rich surface chemistry makes nanodiamond the superior material for reinforcing and tuning polymer matrices, where it can act through changing the properties of the interphase as well as forming a strong covalent interface with the matrix. This chapter summarizes recent developments in applications of nanodiamond in polymer composites.
