Nanocomposites have been under extensive research and development for about 20 years. The key research challenges used to include dispersion of the clay in the resin matrix to achieve a good uniform dispersion of nanoparticles and understanding the properties and potential commercial benefits of the composite materials. There has been a shift in the research direction recently toward modification of the nanoparticles to add functionality for specific property improvements in the final nanocomposite. Examples include the addition of certain metal ions to the nanoparticles so that the resulting nanocomposites have specific functional properties; e.g., the addition of silver ions to the nanoparticles so that the nanocomposite has antimicrobial properties. Also significant advances have been made in the development of nanofibers for thermoplastic reinforcement including processes for manufacture of nanofibers including electrospinning. This month´s R&D highlights will present a few of the key recent advances in nanocomposites.
