The chemistry we provide makes it easy to design imprinting templates according to the customers’ own requirements.
The imprinting template:
The imprinting template comprises a pre-defined surface relief structure, the surface relief structure being arranged to be imprinted on the sample substrate.
The imprinting template can take any suitable form. However, in general, it should be formed from a flexible material which is operable to conform to the curvature of the cylinder. It can be formed from any suitable material transparent for 395nm, for example, a polymeric material such as:
Polydimethylsiloxane (PDMS)
Cyclic Olefin Copolymer (COC)
Polyethylene, Polymethylpentene (PTX)
Polypropylene (PP)
a light-curing resin/polymer
The imprinting template is placed on the cylinder in a position that will ensure that it is in register with, and rotatably aligned with, the substrate so that when the movable plate moves the substrate to the nip, the imprinting template will engage correctly with the sample substrate and transfer the desired pattern to the substrate.
