Insights of durability under aging of poly(methyl methacrylate)/poly(urethane) networks added with poly(methyl methacrylate)-grafted-crystalline nanocellulose particles for engineering applications.

Key Points

• This research examines how adding grafted crystalline nanocellulose affects the durability of PMMA/PU networks under aging.
• Developed PMMA/PU interpenetrating networks (IPNs) for advanced optical applications.
• Utilized crystalline nanocellulose (CNC) from recycled materials as organic fillers.
• Studied structural and mechanical changes under accelerated weathering conditions.
• Enhanced interfacial adhesion due to hydrogen bonding was observed.
• Long-term stability of IPN composites improved with the addition of PMMA-g-CNC particles.
• The structural evolution indicates significant durability under accelerated aging conditions.
