Ala.-.alanylons [exclusive] -

Like all nylons, are hygroscopic (2-5% water absorption). However, the methyl side groups create hydrophobic microdomains, reducing water plasticization compared to Nylon 6. More importantly, the dense amide network creates an exceptional oxygen barrier—5 to 10 times better than EVOH at high humidity.

A synthetic polyamide famous for its durability and flexibility. By combining these through chemoenzymatic polymerization Ala.-.AlaNylons

| Application | Why Ala.-Ala Nylon? | |-------------|----------------------| | | Enzymatically degradable, non-inflammatory breakdown products (alanine is benign), and high knot strength. | | High-strength fibers (artificial silk) | Beta-sheet crystal structure mimics spider dragline silk. Can be wet-spun into fibers with toughness exceeding Kevlar at similar density. | | Compostable electronics casings | For medical implants or environmental sensors that must disappear after use. | | Chiral separation membranes | The polyalanine backbone can be synthesized in all-L or all-D form, allowing membranes that selectively filter mirror-image drug molecules. | Like all nylons, are hygroscopic (2-5% water absorption)
