Preparation of Organic Thin Films by Using Spin Coating and Langmuir-Blodgett

A thin film is a organic substances layer with nanometer to micrometer thickness. The controlled synthesis of thin films is an important issue in its applications. Organic thin films with nanometer thickness are useful structure for applying in sensors, detectors and electronic circuit components. Spin coating and Langmuir-Blodgett are one of the applicable techniques in thin films preparation. In spin coating centrifugal force drives the liquid radial outward and the viscous force and surface tension causes a thin film to be produced on the flat substrate. Langmuir-Blodgett films are ultra thin organic films with interesting properties such as controllable thickness, uniformity of surface and a high degree of oriented order, which make them possible options for sensors applications. In this article were investigated various aspects of spin coating and
