Reactive polymer coatings chemical vapor deposition

In 1987 he was promoted to distinguished member of the technical staff and technical manager. His efforts broadened to include projects on polymer-surface interactions adhesion promotion corrosion protection chemical vapor deposition and thin film growth optical fiber coating synthesis, structure, and reactivity of model organic surfaces and time-resolved surface vibrational spectroscopy. 

The design of biologically active surfaces offers a new dimension to the development of advanced materials for biomedical and microfluidic applications. Our approach to creating these surfaces is via the fabrication of vapor-based reactive polymer coatings, which provide sophisticated functional groups for the immobilization of biological ligands. Chemical vapor deposition (CVD) polymerization has been used to prepare a wide spectrum of hinctionalized poly(p-xylylenes). The applicability of a few of these reactive surfaces as stable platforms for biomimetic modifications is discussed in this review. 

Vacuum deposition is the deposition of a film or coating in a low pressure plasma environment. The deposition process requires increasing the mean free path for collisions of atoms and ions. In physical vapor deposition processing (PVD), for example, this ionic activity is leveraged to sputter a surface as a source of deposition material and/or bombard a polymer film to modify the film properties. Vacuum plasmas are also used to activate reactive species in deposition processes and fragment chemical precursors in plasma-enhanced chemical vapor deposition (PECVD) processes.
