Pd nanoparticles are the active material of choice for sensor prototype development due to their ability to form a hydride at ambient conditions, which creates the optical contrast. Here, we introduce plasmonic hydrogen sensors made from a thermoplastic nanocomposite material, that is, a bulk material that can be molded with standard plastic processing techniques, such as extrusion and three-dimensional (3D) printing, while at the same time being functionalized at the nanoscale. Specifically, our plasmonic plastic is composed of hydrogensensitive and plasmonically active Pd nanocubes mixed with a poly(methyl methacrylate) matrix, and we optimize it by characterization from the atomic to the macroscopic level. We demonstrate meltprocessed deactivation-resistant plasmonic hydrogen sensors, which retain full functionality even after 50 weeks. From a wider perspective, we advertise plasmonic plastic nanocomposite materials for application in a multitude of active plasmonic technologies since they provide efficient scalable processing and almost endless functional material design opportunities via tailored polymer − colloidal nanocrystal combinations.  \nKEYWORDS: plasmonic nanocomposites, nanoparticles, polymer matrix, melt processing, 3D printing, plasmonic hydrogen sensing  \n■ INTRODUCTION  \nNanoparticles supporting localized surface plasmon resonance (LSPR) enable a wide range of fascinating technologies, where optical bio-and chemosensors1−6 are of particular interest, and where hydrogen sensors show great promise as a key technology in the emerging hydrogen economy,6−8 since safety sensors are critical due to H2’s wide flammability range in air. In this context, optical plasmonic detection is attractive since it generates no sparks due to the passive nature of the transducer and the remote readout capability of light.
