Hydrogen (H2) sensors that can be produced en masse with cost-effective manufacturing tools are critical for enabling safety in the emerging hydrogen economy. The use of melt-processed nanocomposites this context would allow combination advantages plasmonic detection polymer technology; an approach which is held back by slow diffusion H2 through matrix. Here, we show amorphous fluorinated polymer, compounded colloidal Pd nanoparticles prepared highly scalable continuous flow synthesis, results display a high coefficient order 10–5 cm2 s–1. As result, optical melt-pressed no longer limited analyte to nanoparticle transducer elements, despite thickness up 100 μm, thereby response times as short 2.5 s at mbar (≡10 vol. %) H2. Evidently, fast time fabricated thick, nanocomposites, paves way new generation robust sensors.
