Laser-ion acceleration experiments require the use of appropriate targets or foils which can adequately absorb such high-intensity pulses. In this work, parylene-based foils of nanometer thickness are fabricated via a cost-effective and simple process, allowing the production of large-area targets for laser acceleration experiments in the regime of radiation pressure acceleration. Besides the remarkable mechanical stability compared to commonly used diamond-like carbon foils, a very homogeneous layer thickness and a small surface roughness have been achieved.
