Compatibilization of immiscible polymer blends using graphene oxide sheets.
By taking the advantage of the unique amphiphilic structure of graphene oxide sheets (GOSs), we develop here a new and effective strategy for compatibilizing immiscible polymer blends. With the incorporation of only 0.5 wt % GOSs into immiscible polyamide/polyphenylene oxide (PA/PPO, 90/10) blends, the droplet diameter of the dispersed minor phase (PPO) is dramatically reduced by more than 1 or...
متن کاملToughening of biodegradable polylactide/poly(butylene succinate-co-adipate) blends via in situ reactive compatibilization.
Polylactide and poly(butylene succinate-co-adipate) (PLA/PBSA) were melt-blended in the presence of triphenyl phosphite (TPP). An increase in the torque during melt mixing was used to monitor the changes in viscosity as compatibilization of the blends occurred. Scanning electron micrographs showed not only a reduction in the dispersed-phase size with increased TPP content but also fibrillated l...
متن کاملInvestigations on Green Blends Comprising Biodegradable Polymer and Ionic Liquid
The green blends of an ionic liquid, 1-ethyl-3-propylimidazolium bis(trifluoromethanesulfonyl) imide {[EPrI][TFSI]}, and a biodegradable polymer, poly(3hydroxybutyrate) (PHB), were investigated in this study. The influence of an ionic liquid on the crystallization behaviors of a biodegradable polymer was explored. In the blends, the presence of [EPrI][TFSI] decreased the Tg and Tm of PHB. Incor...
متن کاملCompatibilization of Polymer Blends by Complexation. 1. Spectroscopic Characterization of Ion-Amide Interactions in Ionomer/Polyamide Blends
Electron paramagnetic resonance (EPR), Fourier transform infrared (FTIR), and solid-state 15N nuclear magnetic resonance (15N-NMR) spectroscopies were used to characterize the structure and relative strength of the interactions between metal sulfonate and amide groups in blends of lightly sulfonated polystyrene ionomers and an N-methylated polyamide, poly(N,N′-dimethylethylene sebacamide), and ...
متن کاملStarch-based biodegradable blends: morphology and interface properties
In order to improve the properties of plasticized wheat starch (PWS) and to conserve its final biodegradability, PWS can be blended with biodegradable polyesters [polyesteramide, poly(ε-caprolactone), poly(lactic acid), poly(butylene succinate adipate) and poly(butylene adipate terephthalate)] which exhibit variable polar characteristics. This paper is focused on the analysis of the compatibili...
