Elaboration and characterization of bioblends based on PVC/PLA

Journal of Applied Polymer Science, 2013
AbstractWith the aim to develop new biomaterials (bioblends) to be used in the field of waste elimination, this contribution focuses on the elaboration and characterization of new materials based on poly (vinyl chloride) (PVC) and poly (lactic acid) (PLA). The bioblends based on PVC/PLA were prepared by melt mixing in the absence and presence of maleic

Chitosan and Poly(Methyl Methacrylate-Co-Butyl Methacrylate) Bioblends: A Compatibility Study

Polymer-Plastics Technology and Engineering, 2014
Chitosan/poly(methyl methacrylate-co-butyl methacrylate) (PMMA-co-BMA) blends were prepared via a solution blending method in the presence of formic acid. The compatibility of the bioblends was studied by different methods, such as Fourier transform infrared and Raman spectroscopy, micro-Raman imaging, thermogravimetric analyses, differential scanning ...

Biocomposites and Bioblends

2009
Biocomposites and bioblends are receiving great attention for application in several sectors, mainly packaging, agriculture, and medicine. Researchers are in fact investigating the possibility to modify traditional polymer materials to make them more environmental friendly, and design novel polymer composites out of naturally occurring materials.

Polylactide based bioblends

2015
The inherent brittleness of poly(lactic acid) (PLA) resins still limits their wide spectra of applications. Abundant research efforts have been spent in the last decade to overcome this drawback. In this frame, in light of previous investigations, this work reports on a new strategy to improve the toughness of PLA by melt blending with other eco ...

Compatibility study in poly(tetramethyleneadipate‐co‐terephthalate)/polystyrene bioblends

Journal of Applied Polymer Science, 2008
AbstractBioblends of the biodegradable copolyester poly(tetramethyleneadipate‐co‐terephthalate) (EBU) and polystyrene (PS) were prepared in different weight compositions on a twin‐screw extruder at 160–200°C. The various bioblend compositions were then investigated using thermogravimetric analysis (TGA), modulated differential scanning calorimetry ...

Effect of urea and formamide plasticizers on starch/PVA bioblend sheets

Journal of Applied Polymer Science, 2015
ABSTRACTThe starch/polyvinyl alcohol (PVA) bioblend sheets containing urea and formamide as plasticizers were prepared through melt processing in presence of water. The experiments indicated that urea and formamide plasticizers could form strong hydrogen bonds with starch/PVA molecules. Urea exhibited better plasticizing effect than formamide.

Injection-Molded Bioblends from Lignin and Biodegradable Polymers: Processing and Performance Evaluation

Journal of Polymers and the Environment, 2017
This paper investigates the effects of the incorporation of lignin and small quantities of epoxidized natural rubber (ENR) as an impact modifying agent on blends of poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) and poly(e-caprolactone) (PCL). The addition of lignin resulted in a slight improvement of flexural strength and modulus of the ternary ...

Thermal properties of PCL/gluten bioblends characterized by TGA, DSC, SEM, and infrared‐PAS

Journal of Applied Polymer Science, 2008
AbstractComposites of polycaprolactone (PCL) and vital wheat gluten (VG) were extruded, injection‐molded, and analyzed using differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), scanning electron microscope, and Fourier‐transform infrared (FTIR).

BioBlend - Enabling Pipeline Dreams

2013
Since the advent of high-throughput sequencing technologies, genomics has become a large-data science with immense opportunity for biological insight. However, the analysis of such data is technically challenging, and collaboration between biologists and bioinformaticians is required to interpret the data.
