Properties of biodegradable polymer blends before and after Fenton and Basic Piranha oxidation. (3.1) SEM images, (3.2) FT-IR spectra, (3.3) Particle size distributions for (a) PLA_based, (b) PBAT_based, and (c) PBS_based polymer blends (BP: oxidation with Basic Piranha. Fenton: oxidation using the Fenton protocol). The polymer particles were clearly affected by Basic Piranha oxidation but showed no significant change following Fenton oxidation
