Polymer surface grafting is widely used in the field of bone regeneration to increase calcium phosphate (CaP) adhesion, with the intent of improving mechanical properties of CaP-polymer composite cements. Reinforcement can be achieved using multiple combined functional groups and/or complex surface geometries that, however, concurrently influence multiple effects such as wetting, roughness, and interfacial strengthening. This study focused on the influence of a chelating group, namely aspartic acid, on the adsorption of divalent ions such as Ba or Ca onto poly-l-lactic acid (PLA) films.

Electrospun micro- and nanosized fibers are frequently used as reinforcing elements in low temperature ceramic composites for biomedical applications. Electrospinning of fibers yield, however, not individual fibers, but rather fiber-mats that are difficult to separate. Most investigations have been performed on diced mats and highly nonhomogenous composites.

We demonstrate the fabrication of staple polymer-based fibres by the ultrasound-assisted processing of electrospun meshes. Bioabsorbable Poly-L-Lactic Acid (PLLA) was electrospun from organic solvent mixtures, yielding continuous fibres with diameters in the range of 244±78 nm. Subsequently, the obtained fibres were sonicated at low temperatures in the presence of nanoparticles in order to obtain fibres with small aspect ratios.
