Biodegradable PLA composites reinforced with micro and nano Mg particles: optimisation of processing and design, and scale-up of temporary implants - POLYMAGIC

Project summary

The project proposes the optimisation and scaling-up of biodegradable and bioabsorbable composites for osteosynthesis based on a polylactic acid (PLA) matrix loaded with Mg particles in the nano and micrometric range, and processed by thermoplastic methods. Other innovative objectives are related to their processing by a colloidal suspension route to increase homogeneity and particle-matrix bonding, as well as by additive manufacture and electrospinning. The project also considers the sustainability of the whole life cycle of the proposed materials and processing. Potential benefits are related to better mechanical properties, increased bioactivity and antibacterial resistance, and possibility of tailoring degradability of implants by controlling shape and volume fraction of Mg (nano)filler. These temporary implants would improve life quality of patients, especially paediatric, and would open new business opportunities, guaranteed by the two participating SMEs.
