| Abstract | A group of membranes of different materials, including radical and cationic UV lacquer, PFPE urethane methacrylate UV resin (MD700), optical adhesive UV resin with high refractive index (NOA84), as well as thermally curable polydimethylsiloxane (PDMS) have been successfully fabricated by using a simple, yet robust method. The membranes are replicated from an intermediate template with micro- or nano-pillars by using the spontaneous capillary flow (SCF) method. The polymerization is done either by UV or thermal curing. The size of the pores in the membrane ranges from 100 μm down to 200 nm. The thickness of the membranes varies from 10 μm up to 100 μm. As high as 16 of aspect ratio (the thickness of the membrane to the diameter of the pore) has been achieved in membranes with thickness of 100 μm and 6 μm pore diameter. Uniform open-through hole membranes with pore size of 15 μm and thickness of 30 μm over an area of 44×44 mm2 have also been achieved. |
