Potential for a diverse range of functionalities, high throughput and cost effective
About
Overview Porous films with ordered arrays of micro and nano- scale pores can be formed using an inexpensive, self-organisation method. Understanding the mechanism has uncovered a remarkably flexible system that allows a broad range of pore morphologies to be formed. This technology has great potential as pores can be engineered to contain a variety of interesting chemical and biological agents which can add functionality to the films. Alternative porous polymer production methods require costly, complex, multi-stage processing. This technique, developed by CRANN researchers, addresses these issues of control over porosity and pore order in a simple and straightforward manner. Furthermore, loading of active agents is typically achieved by solution dosing following porous film production whereas this technique has the potential to load active agents in a single step during film formation. What Problem Does it Solve & Advantages • Single step synthesis – complete production process integrated to one machine •Simple to operate – control over pore morphology dependent on easily adjustable reaction conditions • Potential for a diverse range of functionalities – simple production technique allows for integration of many different materials into membranes • High throughput – capable of scaling up to industrial production • Cost effective – simple process with low material requirements Possible Applications Applications include: drug infused surface coatings on medical devices, trans dermal drug delivery, scaffolds for cell growth, materials/gas storage, creation of conductive films and functionalised filter membranes. Technology and Patent Status The technology and fundamentals behind its formation is well understood and is at product development stage. The technique used to produce the various surfaces has been protected under a number of patents. These cover the novel processes for the production of elongated pores and control of pore depth.
