Polylactic acid (PLA)
This website provides an excellent overview of PLA as a polymer, its properties, and manufacture. This web article describes the production of lactic acid from biomass by microbial fermentation coupled to a poly-merization process to make PLA. The article is a bit dated and its industrial projections are now seen to be a bit over-optimistic. NatureWorks is the company that started large-scale p...
متن کاملLayer-by-layer bioassembly of cellularized polylactic acid porous membranes for bone tissue engineering.
The conventional tissue engineering is based on seeding of macroporous scaffold on its surface ("top-down" approach). The main limitation is poor cell viability in the middle of the scaffold due to poor diffusion of oxygen and nutrients and insufficient vascularization. Layer-by-Layer (LBL) bioassembly is based on "bottom-up" approach, which considers assembly of small cellularized blocks. The ...
متن کاملFeasibility of Fabricating PAN/TiO2 Electrospinning Nanofibers with UV Protection Property
Introduction: The skin, can be exposed to harmful factors like ultraviolet radiation (UV). Exposure to this physical hazardous agent could be contributed to pigmentation, erythemas, early aging, skin cancer, and DNA damage. The aim of this study, therefore, was to fabricate the polyacrylonitrile (PAN) nanofibers with the UV protection property by the use of various concentrations of titanium di...
متن کاملNanometre diameter fibres of polymer, produced by electrospinning
Electrospinning uses electrical forces to produce polymer fibres with nanometre-scale diameters. Electrospinning occurs when the electrical forces at the surface of a polymer solution or melt overcome the surface tension and cause an electrically charged jet to be ejected. When the jet dries or solidifies, an electrically charged fibre remains. This charged fibre can be directed or accelerated ...
متن کاملThe Degradation of Polylactic Acid Aiber
Polylactic acid (PLA) fiber, also known as corn fiber, is made of corn and other grains through fermentation, polymerization and spinning. Thus it is biodegradable and environmentally friendly. Three kinds of buffer solutions with PH values of 4, 7.2 and 11 were made for the investigation of the degradation properties of PLA. The experimental results showed that the degradation of polylactic ac...
