Deposition Technology Of Organic-Inorganic Nano-Compositr Thin Films

Description

  1. Original vacuum deposition technology of polytetrafluoroethylene (PTFE) thin film. It includes treatment of PTFE vapors with electron beam. But it is neither electron beam evaporation, nor any kind of plasma methods. This feature allows co-deposition of PTFE with fragile organic molecules, thus forming PTFE matrix filled with organic and/or inorganic nano-clusters. Low power not self-sustained RF-plasma can be used for modification of film adhesion and PTFE properties: refractive index value, mechanical strength and flexibility. PTFE films, filled with gold etc. metal nano-clusters; filled with different kinds of polymethine, phthalocyanine, calixarene etc. organic nano-clusters; and filled with both metal and organic nano-clusters were produced. Films of other fluorinated polyolefines and polyparaphenylene sulphide also were produced and filled with nano-clusters.
  2. Oriented growth of organic films onto our vacuum deposited and than rubbed PTFE. Substrate temperature can be 20-800C, which is applicable for using of plastic substrate. Creation of dye quantum dots.
  3. 20 years of experimental research concerned evaporability of organic dyes. Systematic studies of asymmetric dyes evaporability. Huge data of evaporable and not evaporable dyes. How substituents are affecting core chromophore evaporability.
  4. Deposition of complex organic films employing chemical reactions in gas phase or substrate, using purposefully constructed compounds.
  5. Creation of the nano-sized active units, using ultra-thin films of purposefully constructed compounds and acting on them by AFM tip for chemical reactions in nano-volume.

Innovative Aspect and Main Advantages

  1. Only this technology allows PTFE film deposition with independent modification of film characteristics and co-deposition with other organic molecules on the not heated substrate.
  2. New stable evaporable compounds with controlled intra- and intermolecular interactions.
  3. Organic functional films with extra stability.
  4. Backgrounds for nano-sized optics and electronics.

Areas of Application

  1. Low-k dielectric for microelectronics, waveguiding films in all UV-VIS-NIR range and protective barrier coatings. Beam splitter, modulator, optical switch and logic units in integrated-optic devices. Sensitive layers for artifical nose etc. bio- aggressive- toxic- compounds sensors.
  2. Passive and active layers in organic light emitting devices, flat panel displays, organic electronics and flexible plastic logic.
  3. Nano-sized electronics, plasmonics and photonics, superhigh density information storage.

Hey there! I know this is kind of off topic but I was wondering which blog platform are you using for this
site? I'm getting sick and tired of Wordpress because I've had problems with hackers and I'm looking at
options for another platform. I would be great if you could point me in the direction of
a good platform.

Hey there, I think your site might be having browser compatibility issues.

When I look at your blog site in Chrome, it looks fine but when opening in Internet Explorer, it has some overlapping.
I just wanted to give you a quick heads up!
Other then that, terrific blog!

I'm not sure where you're getting your info, but great topic.
I needs to spend some time learning much more or understanding more.
Thanks for mqgnificent info I was looking for this information for my mission.
