Electrospinning is a fabrication process that uses an electric field to control the deposition of polymer fibers onto a target substrate. This electrostatic processing strategy can be used to fabricate fibrous polymer mats composed of fibre diameters ranging from several microns down to 10 nm. Electrospinning is a simple and versatile method for producing ultra-fine fibres from a variety of materials, including polymers, composites and ceramics.
Fibre spinning capabilities include an experimental size and pilot production mono and multi filament fibre spinning unit. The research facility has an ability of production multi-component fibre spinning capabilities (Bi/tri-component spinning technology). The facility can be used for investigating the new development of materials (biopolymer, conducting polymer) for bionics, batteries, sensors and biomedical application.
Knitting and Braiding:
Knitting – Braiding typically involves a higher number of individual fibres than most other biomedical textile engineering techniques, which allows for greater intricacy and performance capabilities in created structures. Implantable applications that undergo more severe instances of stress and stretch are often able to achieve the higher strength characteristic of ceramic or metal along with a lifelike movement of the fibrous composition. The structures produced have good stretch and high strength in a thin form factor, which can take advantage of the multitude of design options in permanent and absorbable materials to fulfill specific device capabilities.
The system applies a pin-hole free, thin film polymer coating for insulation, elastomeric sealing, packaging and protection of electronic circuits, devices and medical implants.
Used to determine the height and roughness of films in the range of 10s nm to 100s um. Among other things this has been used to characterise films used in a wide varierty of solar and water splitting applications.
Used to determine the current voltage response of organic solar cells and dye sensitised solar cells under simulated sunlight and a range of reduced light intensitites.
Used to determine the spectral response of organic solar cells and dye sensitised solar cells.
Used to desposit controlled thickness layers, typically of metal oxide semiconductor based pastes. It has been used to produce TiO2 and NiO layers for making dye sensitised solar cells and water splitting applications for a range of projects.
Mechanical doctor blade machine:
Has been used to make uniform and reproducible coatings of conductive polymer (and blended conductive polymer: PCBM) for evalutation of new materials and organic solar cells, as well as Ni metal pastes for water splitting applications.
Used to create thin, uniform metal layer, this has been used to apply metal contacts to organic photovoltaic devices.
Fuel cell testing system:
Fuel cell testing system is available for Single-Cell testing, which is only used for PEM Fuel Cell in order to identify the real-cell performance for fully developed catalysts.
