Název projektu:
Plasma barrier coatings on polymer materials (09 DE 1380 3F07)
Popis:
An institute of a German university specialised in low-pressure microwave plasmas has developed plasma processes applicable at the industrial level for surface treatment and coating convenient for a great variety of polymers. Plasma coatings provide excellent multiple barrier properties towards gas diffusion in particular. Plasma surface pre-treatment produces excellent adhesion even to thermally sensitive polymers. The institute is looking for industrial partners for technical co-operation.
Požadavky na partnera:
An institute of a German university has developed diverse low-pressure plasma processes based on large-area homogeneous microwave plasma sources easily scalable and adaptable to industrial requirements. These plasma sources offer a great variety of combinable applications in surface treatment, for example coating, activation, functionalisation, cleaning and sterilisation.
Low-pressure plasma deposition of barrier coatings on polymers offers an efficient means to overcome the disadvantages concerning missing barrier properties of homo-polymeric materials increasingly replacing expensive and material consuming multi-layer polymer materials.
Preventing the diffusion of organic solvents into and through polymers often poses a big challenge. Plasma deposited barrier coatings provide excellent barrier properties towards hydrocarbons, reducing the corresponding permeability of the polymers by several orders of magnitude.
Due to the disposability of different low-pressure microwave plasma sources designed and developed by the institute, customised plasma processes can easily be developed for deposition of homogeneous dielectric barrier coatings,
- e.g. silicon oxide (SiOx), silicon nitride (SiNy), silicon carbide (SiC) and compositions thereof,
- on 2-dimensional materials (e.g. packaging foils) or on 3-dimensional substrates (e.g. bottles)
- in a batch or in an inline process, depending on the specific requirements.
Deposited on polymer materials used for packaging for instance, dielectric barrier coatings on nano-scale provide efficient barrier properties towards
- oxygen,
- carbon dioxide,
- water vapour and
- organic solvents
for example, thus providing an efficient protection of the packaged goods by simultaneously offering or maintaining a multitude of additional functionalities like
- optical transparency,
- high flexibility,
- acid resistance,
- microwave transparency, etc.
of the plasma coated polymer packaging material.
Low-pressure microwave plasma deposition of dielectric coatings on nano-scale offers
- customised adaptation of the chemical composition (e.g. silicon oxide, silicon nitride, silicon carbide or a mixture thereof) and of the coating thickness as well as
- mechanical flexibility
of the barrier films according to the specific demands.
A low-pressure microwave plasma setup based on the electron cyclotron resonance (ECR) principle facilitates plasma treatment and coating of even thermally sensitive polymers.
The frequently insufficient adhesion of the barrier coatings to the surface of the polymers can be significantly improved by plasma pre-treatment.
Corresponding to the requirements of the industrial partners,
a customised plasma process will be developed and
the setup of the plasma source used for surface treatment will be designed accordingly.
The easy scalability of the plasma sources to industrial level essentially facilitates the development of customised plasma processes.
Complementary to the development of the plasma process for surface modification and to the customised setup of the plasma source, the institute will offer in-situ and ex-situ analysis to control the proper performance of the process.
The institute is in a co-operation with an equipment builder that optionally will provide support in the technical implementation of the process.
Innovative Aspects:
Dielectric barrier coatings on nano-scale plasma deposited on polymer materials used for packaging for instance by low-pressure microwave plasma processes provide efficient barrier properties towards
- oxygen,
- carbon dioxide,
- water vapour and
- organic solvents
for example, additionally creating or maintaining the multi-functional properties like
- optical transparency,
- high flexibility,
- acid resistance,
- microwave transparency, etc.
of the polymer material.
In addition, low-pressure microwave plasma deposition of dielectric coatings on nano-scale offers
- customised adaptation of the chemical composition (e.g. silicon oxide, silicon nitride, silicon carbide or a mixture thereof) and of the coating thickness,
- mechanical flexibility and
- excellent adhesion to the polymer surface
of the barrier films according to the specific demands
and is applicable even on thermally sensitive polymer materials.
