Future nanotechnology developments for automotive applications

چکیده
In the automotive industry, nanotechnology applications are manifold. They reach from power train, light-weight construction, energy conversion, pollution sensing and reduction, interior cooling, wear reduction, driving dynamics, surveillance control, up to recycle potential and much more. Additionally, visions of ‘‘nano in cars’’ reach from contributions for CO2-free engines, safe driving, quiet cars, self-healing body and windscreens, up to a mood-depending choice of colour and a self-forming car body. All this will meet the present society trends and customer demands for improved ecology, safety and comfort, often summarised by the term sustainability. For automotive components nanoparticles, -dots, -pores, -fibers, -tubes, -whisker, -layers, either dispersed within a matrix material and called ‘‘nanocomposites’’, or arranged on surfaces or used as a discrete material and then called ‘‘nanostructures’’, offer exclusive potential. Volume effects like diffusion, absorption and mechanical strength might be tailored, furthermore surface effects like adsorption, hardness, and catalytic reaction. Selforganisation of structures will play an essential role in growth, deposition and etching. We will present an overview about existing nanotechnologies in cars already on the market, applications with short-term and medium-term potential as well as long-term applications such as light-weight construction using nano-carbon nanotubes which are presently investigated in research labs worldwide and have a high potential if they can be used for automotive bodies.
