Abstract

A mold (35) for use in nano- or micro-replication processes on thermoplastic polymer substrates (20), comprises a nano- or micro-structured fluoropolymer surface that, when the mold (35) is used in a nano- or micro-replication process, serves for the application of a nano- or micro-structuration on a thermoplastic polymer substrate (20,22). The nano- or micro-structured fluoropolymer surface is itself obtained by nano- or micro-structuration against the fluoropolymer surface (30) using a master mold (10) of silicon, quartz, nickel, steel, copper, or another material of comparable properties having a nano- or micro-structuration corresponding to that to be applied to a substrate (22). The fluoromold (35) can be used for nano- or micro-imprint lithography, or a liquid polymer can be coated or extruded against the nano-or micro-structured fluoropolymer surface.

Thermoplastic elastomer

Thermoplastic elastomers (TPE), sometimes referred to as thermoplastic rubbers, are a class of copolymers or a physical mix of polymers (usually a plastic and a rubber) that consist of materials with both thermoplastic and elastomeric properties. While most elastomers are thermosets, thermoplastics are in contrast relatively easy to use in manufacturing, for example, by injection moulding. Thermoplastic elastomers show advantages typical of both rubbery materials and plastic materials.

Radical polymerization

In polymer chemistry, free-radical polymerization (FRP) is a method of polymerization by which a polymer forms by the successive addition of free-radical building blocks (repeat units). Free radicals can be formed by a number of different mechanisms, usually involving separate initiator molecules. Following its generation, the initiating free radical adds (nonradical) monomer units, thereby growing the polymer chain. Free-radical polymerization is a key synthesis route for obtaining a wide variety of different polymers and materials composites.

Nanolithography

Nanolithography (NL) is a growing field of techniques within nanotechnology dealing with the engineering (patterning e.g. etching, depositing, writing, printing etc) of nanometer-scale structures on various materials. The modern term reflects on a design of structures built in range of 10−9 to 10−6 meters, i.e. nanometer scale. Essentially, the field is a derivative of lithography, only covering very small structures. All NL methods can be categorized into four groups: photo lithography, scanning lithography, soft lithography and other miscellaneous techniques.
