Bioresorbable piezoelectric polymeric devices offer great potential for biomedical applications, particularly in implantable bioelectronics [1]. Poly(L-lactide) (PLLA), despite its intrinsic piezoelectric properties, presents significant limitations such as inherent brittleness, poor thermal stability, and prolonged bioresorption times [2]. In this study, polymeric blends based on PLLA and poly(L-lactide-co-caprolactone) (PLCL) were formulated to overcome these drawbacks and thoroughly characterized in terms of piezoelectric response, mechanical properties and degradation rates [3]. PLCL was incorporated in various weight ratios (PLLA, 90:10, 80:20, 70:30, 60:40) and films were fabricated in three structural states with varying degrees of macromolecular orientation and crystallinity: (1) unstretched amorphous films (DR1), (2) 400% stretched quasi-amorphous films (DR4), and (3) 400% stretched films with post-annealing at 80 °C to induce oriented crystalline domains (DR4AN80). The results demonstrated that PLCL can be incorporated up to 40 wt.% without compromising the piezoelectric response while enabling the modulation of mechanical properties. Accordingly, films with reduced stiffness and increased flexibility and toughness were obtained. The addition of PLCL also enhanced thermal stability, facilitating the processing of the materials via advanced manufacturing techniques (e.g., melt electrowritting). These findings highlight the potential of PLLA:PLCL piezoelectric blends for applications in implantable bioelectronic devices, soft robotics, and tissue engineering scaffolds, where tunable mechanical and electrical properties are required.
