파릴렌 고분자의 특성 및 그 응용

Abstract

Parylene polymer thin film shows excellent homogeneous coverage chracteristics when it was deposited onto very complex three dimensional solid matters, such as deep hole and micro crack. The parylene deposition process can be conducted at room temperature although most of chemical vapor deposition processes request relatively high processing temperature. Therefore, the parylene coating process does not induce any thermal problems. Parylene thin film is transparent and has extremly high chemical stability. For example, it shows high chemical stability with high reactive chemical solutions such as strong acid, strong alkali and acetone. The bio-stability of this material gives good chances to use for a packaging of biomedical devices and electronic devices. In this review article, principle of deposition process, properties and application fields of parylene polymer thin film are introduced.
