The Ghost in the Molecule
The durability paradox and the future of degradable polymers.
- The Paradox
Engineered Immortality
The same chemical stability that makes carbon fiber and Bakelite revolutionary also makes them nearly immortal. Modern polymers are designed to resist the very nature they inhabit.
- Material Cost
The Environmental Ghost
Because synthetic bonds don't exist in the natural cycle, microbes lack the 'keys' to unlock them. Plastics don't disappear; they simply shatter into microscopic fragments.
- Thermoset Trouble
One-Way Streets
Thermoset plastics, like those used in aerospace, are cross-linked into a single giant molecule. Unlike thermoplastics, they cannot be melted and reshaped once cured.
