Impact of hydrolysis pretreatment on the compostability of biodegradable poly(caprolactone) and poly(lactic acid) films
AI summary Read the abstract
Researchers found that hydrolysis pretreatment significantly accelerates biodegradation of PLA plastic films in composting conditions by breaking down its amorphous regions and reducing molecular weight, while the same treatment had minimal effect on the already more biodegradable PCL polymer.
Hydrolysis pretreatment accelerated PLA biodegradation by disrupting its amorphous regions, reducing molecular weight, and forming less stable crystalline structures, while its impact on PCL was minimal.

The Hydrolytic Behavior of Poly(Lactic Acid)/Polystyrene‐ Grafted‐Hectorite Nanocomposite Films and Its Regulatory Mechanism on Microplastics
AI summary Read the abstract
Researchers tested how polylactic acid (PLA) films and PLA/hectorite nanocomposite films degrade in aqueous solutions of different pH levels. The nanocomposite films degraded more slowly and released fewer microplastic fragments than pure PLA, suggesting that clay mineral incorporation could reduce secondary microplastic generation from biodegradable plastics.
