45、ymerization of lactic acid polylactic acid by chemical methods for the polymerization of lactic acid polylactic acid by chemical methods for the polymerization of lactic acid polylactic acid and chemical methods for the polymerization of lactic acid polylactic acid, or waste to the production of ...
The focus of the current study was to develop a functional and bioactive scaffold through the combination of 3D polylactic acid (PLA)/polycaprolactone (PCL) with gelatin nanofibers (GNFs) and Taurine (Tau) for bone defect regeneration. GNFs were fabricated via electrospinning dispersed in PLA/PCL ...
(PLA) is summarized.There are two modification methods,chemical and physical method,respectively.The chemical modification aims to improve the brittlenesshydrophobic property and degradation rate of PLA by changing its macromolecular structure or surface feature,including copolymerizationcrosslinking and surface...
Polylactic Acid: Synthesis, Properties and Applications L. Avérous ABSTRACT Polylactic acid (PLA) is at pres..
Polylacticacid (PLA) was submitted to high-flux carbon ion implantation with energy of 40 keV. It was investigated to the effect of ion fluence (1 × 10 12–1 × 10 15 ions/cm 2) on the properties of the polymer. X-ray photoelectron spectroscopy (XPS), atomic force microscopy (AFM),...
processes include pyrolysis,acidic hydrolysis,basic hydrolysis,neutral hydrolysis,high-temperature high-pressure hydrolysis,enzyme catalysis,methanol alcoholysis,n-butylalcohol alcoholysis,and so on.The feasibility of polylactic acid chemical depolymerization in ionic liquor environment is discussed and prospected....
