Nylon is commonly used in many industries, ranging from construction to clothing. Most common nylons are even-numbered and petroleum based, but odd-numbered nylons may offer unique properties. Nylon 5,9 is a particularly interesting odd-numbered nylon because both molecules can be bio-based, derived from vegetable oil and fermented low-value sugar. Being bio-based means 5,9 offers a sustainability edge over 6,6 without compromising on material integrity, while showing unique properties suitable for new applications. This research found that 5,9 performed similarly to 6,6 in elastic modulus and yield strength, with higher toughness. Additionally, 5,9 shows lower melting and crystallization temperatures, and higher degradation temperatures than 6,6 creating a larger window for synthesis and processing without risking degradation. Nylon 5,9 is a promising polymer with little existing research, which could increase sustainability in nylon and bring new possibilities to applications for nylons in industry. |
