“…Certain polymers, however, lend themselves to evaporation [43,44] or sputtering. [45] In our evaporation processes, the nanoparticle containing polymer matrix is produced either by evaporation of the monomers and polycondensation on the substrate [21] or by thermal cracking of suitable polymers like Teflon AF (TAF), and partial repolymerization of the fragments on the substrate.…”

“…[45] In our evaporation processes, the nanoparticle containing polymer matrix is produced either by evaporation of the monomers and polycondensation on the substrate [21] or by thermal cracking of suitable polymers like Teflon AF (TAF), and partial repolymerization of the fragments on the substrate. [22,43,46] Vapor phase co-deposition of noble metals and various polymers (Nylon 6, TAF, and PMMA) was successfully used to produce polymer/metal nanocomposites with a wide range of the metal volume filling factor. [34] For example, Figure 1 shows the morphology variations of Nylon-Ag composite films at different metal filling factors.…”

Nanocomposites combine favorable features of the constituents on the nanoscale to obtain new functionalities. The present paper is concerned with the preparation of polymer‐based nanocomposites consisting of metal nanoparticles in a polymer matrix and the resulting functional properties. Emphasis is placed on vapor phase deposition which inter alia allows the incorporation of alloy clusters with well defined composition and tailored filling factor profiles. Examples discussed here include optical composites with tuned particle surface plasmon resonances for plasmonic applications, magnetic high frequency materials with cut‐off frequencies well above 1 GHz, sensors that are based on the dramatic change in the electronic properties near the percolation threshold, and antibacterial coatings which benefit from the large effective surface of nanoparticles and the increased chemical potential which both strongly enhance ion release.

Continuous production of ultrathin polymeric nanofilms using the spontaneous film formation technique

ABSTRACT:The paper deals with a unique continuous laboratory process for the manufacture of ultrathin nanofilms of various thermoplastic polymers, such as polycarbonate, polyetherimide, polysulfone, and liquid crystalline polyester, based upon the recently developed spontaneous film formation technique. Continuous films with a width up to 14 cm and a thickness of 20-100 nm were produced using a prototype laboratory apparatus at a windup velocity of 1-20 m/min. The length of the film can be almost infinite, i.e. longer than 1 km. The produced films are of high quality and can be used as layer materials, as membranes, in optical devices and sensors, as well as for microlithographic

“…[3,4] VDP was also used to fabricate thin films with intrinsic molecular orientation parallel or perpendicular to the substrate, which can be controlled by the nature of the substrate and the deposition conditions. [5] Generally, molecules orient parallel to the surface at lower and perpendicular at higher substrate temperatures. [6,7] In this paper we report the combinatorial synthesis and in situ orientation of polyimide thin films prepared by VDP.…”

Summary: A combinatorial study on the synthesis and in situ orientation of polyimide thin films by vapor deposition polymerization was carried out. The combinatorial libraries consisted of sectors with different thicknesses, compositions, and with or without alignment layers. Monomers were selected to prepare rigid rodlike polyimides and to optimize their orientation during deposition and the imidization process. Vapor deposition of the monomers was performed sequentially or by coevaporation. By using this combinatorial approach the polymerization and the orientation behavior can be simultaneously studied and optimized by variation of film thickness, film composition, and deposition sequence.The combinatorial substrate for sequential evaporation consists of sectors with three PTFE alignment layers (rows B, C, and E) on quartz glass for UV/Vis measurements.magnified imageThe combinatorial substrate for sequential evaporation consists of sectors with three PTFE alignment layers (rows B, C, and E) on quartz glass for UV/Vis measurements.
