A Novel Media-Concentration Based Accelerated Hydrolytic Degradation Model for Biodegradable Polymers Based on Time-Concentration Superposition Frameworks
… In this study, the hydrolytic degradation of polyglycolide (PG) was investigated in both real-time (PBS) and accelerated (NaOH) media to explore the validity of a Time-Concentration Superposition (TCS) framework applied to accelerated degradation tests in terms of their ability to predict real …

Fully-renewable and degradable thermoplastic elastomers.
… renewable feedstocks, poly(3-hydroxybutyrate), polyglycolide, and polylactide (PLA), have high stiffness and tensile strength, but are inherently brittle, thus limiting the potential for these polymers to replace elastic and ductile polymers derived from fossil fuels. The work described in this …

Biodegradable polymers for the sustained release of antisense nucleic acids
… and ribozymes. Polymers such as polylactide, polyglycolide, polyhydroxybutyrate and polyhydroxyvalerate were used due to their biocompatability and non toxic degradation products. Release profiles of antisense nucleic acids from films over 28 days was biphasic, characterised by an initial …

Structure-property-processing relationships between polymeric solutions and additive manufacturing for biomedical applications
… Other polymers such as polylactide and polyglycolide possess hydrolytically cleavable functionalities, which enables degradation in the body. Non-covalent bonds, such as hydrogen bonding and electrostatic interactions, enable strong connections capable of holding materials together, but …

A phenomenological mathematical modelling framework for the degradation of bioresorbable composites
Understanding, and ultimately, predicting the degradation of bioresorbable composites made of biodegradable polyesters and calcium-based ceramics is paramount in order to fully unlock the potential of these materials, which are heavily used in orthopaedic applications and also being considered for …
