In brief

it4ip shares its expertise and knowledge with customers to develop innovative devices where the membrane filter is the key element ensuring device efficiency.

Applying the track-etching technology to 3D devices as balloons and tubes opens the door to powerful new applications and opportunities.

it4ip also designs and produces an array of devices supporting the porous membrane for your custom application (membrane welded on a supporting frame, specialty filter components for pap tests…).

More than a membrane

Membrane on molded parts

Device samples 2Integrated in a vast network of suppliers and manufacturers, it4ip is well placed to carry out the mounting of the membranes on injection-molded plastic parts.

The expertise goes from design of the part to production, going through membrane welding.

3D devices

StentThe track-etching technology may be applied to a range of polymers and even some ceramics. Its application is not restrained to polymer films and pores can be created into 3D devices.

Coronary balloons can be pierced using the it4ip track-etching process to control their diffusion properties.

Pores with well defined shapes and diameters have been pierced, among others, through

  • Tubes
  • Shells
  • Coronary balloons

It is also possible to track-etch glass for very specific applications.

2D supports

Supports 3Supported nanoporous track-etched templates can be fabricated using track etching technology on polymer films or polymer layers deposited on varied substrates like wafer, glass or metal … and incorporating a potential electrical circuitry.

These templates are useful for the synthesis of metallic or polymeric nano-objects and are therefore used for the growth within their pores of arrays of controlled metallic – single (Co, Ni, Au), alloys (CoFe, NiFe), multilayered (Co/Cu) – nanowires.
Supported porous templates can be also prepared from (i) thin polycarbonate or polyimide layer deposited on top of patterned ITO coated glass and used therefore as template for the confinement of emitting polymer into poly-LED or OLED devices, or from (ii) thick polycarbonate layers deposited on top of copper or nickel coated PET or PEN film for synthesis of bilayered Ni-Au nanowires with applications in biological field.
