Bioerodible polymers offer a unique combination of properties that can be tailored to suit nearly any controlled drug delivery application. By far the most common bioerodible polymers employed for biomedical applications are polyesters and polyethers (e.g., polyethylene glycol), polylactide, polyglycolide and their copolymers). These polymers are biocompatible, have good mechanical properties, and have been used in...

One of the most studied blends has been the one composed of P(3HB) and polylactide, both commercially available polymers with superior thermal and mechanical properties than other commercial polymers. Polylactide is a chemically synthesized, biodegradable thermoplastic and derived from renewable resources. It has been shown that this blend exhibited greater flexibility and hydrolytic biodegradation than the Polylactide or P(3HB) alone [75].

Bacterial cellulose-modified sisal and hemp fibres have also been used to produce unidirectional natural fibre reinforced CAB and polylactide (PLLA) model composites [9]. The mechanical properties of bacterial cellulose-coated sisal fibre reinforced polymers showed significant improvements over neat polymers (Table 6.8). The tensile strength and modulus for sisal/PLLA composites improved by as much as 68 and 49%, respectively. However, improvements were...
