Surface Modification and Characterization of Polylactic Acid (PLA) 3D printed structures for Cell culture applications.

Pokharna P., Ghantasala M., Rozhkova E., Western Michigan University, US

The main aim of this research is to understand the surface modification effects and improve the surface properties of 3D printed scaffolds that would be biocompatible and support the growth and proliferation of cells. Polylactic [...]

Cellulose Nanocrystals as Barrier Performance Enhancer of Extrusion-Blown PLA Films for Food Applications

Matuana L.M., Karkhanis S.S., Stark N.M., Michigan State University, US

Bio-based plastics from sustainable resources such as biomass are the best alternative to petroleum-based polymers because they provide solutions for reducing the general dependency on oil availability and environmental concerns about the use of common [...]

Novel Green Polymer Composites: Major Enhancements in the Crystallization Kinetics of Poly(lactic acid) and Mechanical Properties of Polypropylene Created via Solid-State Shear Pulverization

Brunner P.J., Torkelson J.M., Kane N., Northwestern University, US

Hybrids of polylactide (PLA) or polypropylene (PP) with microcrystalline cellulose (MCC) were created using a continuous, industrially scalable, and environmentally benign process called solid-state shear pulverization (SSSP). The PLA composite was subsequently melt-processed (MP) with [...]

Biological effects of PLA-TCP nanocomposites on osteoblastic cells

Kim H.W., Kim J.W., Kim T.I., Lee H.-H., Lee S.-P., Kim H.W., Kim J.W., Kim T.I., Kim H.W., Kim J.W., Kim T.I., Lee H.-H., Lee S.-P., Seoul National University, KR

Composite substrates are considered as prospective matrix to populate and support cells in the bioengineering field. Synthetic degradable biomaterials, including poly(lactic acid) (PLA) and tricalcium phosphate (TCP), are widely used for matrix scaffold. In present [...]

The study of using glycidyl methacrylate grafted natural rubber as an impact modifier of polylactic acid

Juntuek P., Ruksakulpiwat C., Ruksakulpiwat Y., humsamrong P., Ruksakulpiwat C., Ruksakulpiwat Y., Suranaree University of Technology, TH

Glycidyl methacrylate (GMA) was grafted onto natural rubber (NR) using emulsion polymerization method and using cumene hydroperoxide (CHP) and tetraethylenepentamine (TEPA) as an initiator. Glycidyl methacrylate grafted natural rubber (NR-g-GMA) were melt blended with polylactic [...]
