Francesco De Bon's Quest for Greener Plastics
Imagine a world where plastics assemble themselves with atomic precision, where complex polymers form without toxic residues, and where essential materials like PVC (polyvinyl chloride) are produced sustainably.
This isn't science fiction—it's the groundbreaking work of Dr. Francesco De Bon, a polymer chemist revolutionizing how we build molecules. At the intersection of electrochemistry and radical polymerization, De Bon's innovations tackle one of chemistry's toughest challenges: controlling the chaotic world of free radicals to create cleaner, smarter plastics. His breakthroughs offer hope for an industry seeking sustainable alternatives, proving that electricity might be the secret ingredient for greener materials 2 .
eATRP reduces catalyst use by >90% and enables precise control over polymer chain growth.
Most plastics form through radical polymerization—a process where reactive molecules chain together like frenzied dancers. Traditional methods struggle to control these chains, leading to uneven structures that compromise material performance. Enter Atom Transfer Radical Polymerization (ATRP), a Nobel-recognized technique that uses catalysts to tame radicals. But even ATRP has drawbacks: high catalyst toxicity and sensitivity to oxygen.
De Bon's solution? Electrochemically Mediated ATRP (eATRP). By applying electric currents, he manipulates catalyst oxidation states, turning polymerization "on/off" like a switch. This slashes catalyst use by >90% and eliminates the need for harsh chemical activators.
"Electricity replaces chemical reducing agents, making polymerization greener and more precise."
Many critical monomers—like vinyl chloride (VC)—are gases at room temperature. Polymerizing them traditionally requires high pressure, toxic catalysts, and generates wasteful byproducts. De Bon's eATRP breakthrough enabled VC polymerization under mild conditions, opening doors to sustainable PVC production 2 .
In 2020, De Bon's team achieved the first electrochemical polymerization of VC using a surprisingly simple setup 2 :
| Target Mâ‚™ (g/mol) | Achieved Mâ‚™ (g/mol) | Dispersity (Ä) |
|---|---|---|
| 10,000 | 10,800 | 1.28 |
| 20,000 | 21,200 | 1.31 |
| 50,000 | 52,100 | 1.35 |
The experiment yielded PVC with unprecedented control:
Near-perfect molecular weight matches between theory and practice
Uniform chain lengths (Ä < 1.35) - unprecedented in VC polymerization
Enabled block copolymer synthesis (e.g., PVC-b-PMMA)
This work proved eATRP's scalability for gaseous monomers, bypassing 50 years of PVC production challenges. 2
| Reagent/Material | Function | Innovation Edge |

| SS304 Reactor | Dual-use vessel/cathode | Simplifies setup, reduces costs |
| Cuâº/TPMA catalyst | Electron shuttle for ATRP | Oxygen tolerance; ppm-level use |
| Ionic liquid solvents | Electrolyte medium | Stabilizes radicals; recyclable |
| Alternating current | Polymerization trigger | Avoids electrode fouling |
| Degassing agents | In situ Oâ‚‚ scavenging (via electrolysis) | Enables open-vessel reactions |
De Bon's recent work tackles industrial barriers:

Francesco De Bon's work transcends lab curiosity—it reimagines chemical manufacturing.
By merging electrochemistry with radical chemistry, he offers a toolkit to redesign materials at the atomic level. From safer PVC pipes to smart biomedical hydrogels, his eATRP platform proves that sustainability and precision can coexist. As industries race to decarbonize, De Bon's electrochemical alchemy lights the path toward plastics that serve humanity without costing the Earth.
