Polymer-Nanoparticle Hybrid Materials for Plasmonic Hydrogen Detection
May 30, 2023
Plasmonic metal nanoparticles and polymer materials have independently undergone rapid
development during the last two decades. More recently, it has been realized that combining
these two systems in a hybrid or nanocomposite material comprised of plasmonically active
metal nanoparticles dispersed in a polymer matrix leads to systems that exhibit fascinating
properties, and some first attempts had been made to exploit them for optical spectroscopy,
solar cells or even pure art
Welcome message from author
In my thesis, I have applied this concept to tackle the urgent problem of hydrogen safety by developing Pd nanoparticle-based “plasmonic plastic” hybrid materials, and by using them as the active element in optical hydrogen sensors. This is motivated by the fact that hydrogen gas, which constitutes a clean and sustainable energy vector, poses a risk for severe accidents due to its high flammability when mixed with air.
