(1)Poortoughness——PLA is a very brittle material with less than 10% elongation at break.Although its tensile strength and elastic modulus are comparable to poly(ethyleneterephthalate) (PET), the poor toughness limits its use in the applications thatneed plastic deformation at higher stress levels screws and fracture fixationplates.
(2) Slow degradation mte——-PLA degrades through the hydrolysis of backboneester groups and the degradation rate depends on the PLA crystallinity, molecularweight, molecular weight distribution, morphology, water diffusion rate into thepolymer, and the stereoisomeric content. The degradation rate is often consideredto be an important selection criterion for biomedical applications. The slowdegradation rate leads to a long life time in vivo, which could be up to years insome cases. There have been reports of a second surgery almost 3 years afterimplantation to remove a PLA-based implant. The slow degradation rate is aserious problem with respect to disposal of consumer commodities as well.
(3) Hydrophobicity——PLA is relatively hydrophobic, with a static water contactangle of approximately 80 This results in low cell affinity, and can elicit aninflammatory response from the living host upon direct contact with biologicalfluids.
(4) Lack of reactive side-chain groups——PLA is chemically inert with noreactive side-chain groups making its surface and bulk modifications a challengingtask. The successful implementation of PLA in consumer and biomedicalapplications relies not only on mechanical properties being better than orcomparable to conventional plastics, but also on controlled surface properties(such as hydrophilicity, toughness, and reactive functionalities). PLA has been bulkmodified mainly to improve toughness and degradation rate. The surfacemodification of PLA has been attempted to control hydrophilicity, toughness,and to introduce reactive groups. The toughness improvement is a crucial necessityfor many consumer applications, while the improvements in hydrophilicity andintroduction of reactive groups are beneficial to biomedical applications. Theimprovements in degradation rate could be important in both consumer andbiomedical applications.
