Toughening 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 کاملCompatibilization 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 کاملFunctionalization, Compatibilization and Properties of Polyolefin Composites with Natural Fibers
The article is focused on analyzing the effect of functionalization and reactive processing on the morphological, thermal, rheological and mechanical properties of composites of isotactic polypropylene (PP), polystyrene (PS), poly(ethylene-vinyl acetate) (EVA), with cellulose fibers, hemp or oat as natural fillers. Both polymers and fibers were modified with bi-functional monomers (glycidyl met...
متن کاملA new biodegradable blends prepared from polylactide and hyaluronic acid
In this article, the biodegradable polylactide/hyaluronic acid (PLA/HA) composites were prepared by a melt blending method. In addition, the acrylic acid grafted polylactide (PLA-g-AA) was studied as an alternative to PLA. The samples were characterized by a fourier transform infrared (FTIR) spectroscopy, a nuclear magnetic resonance (NMR), a differential scanning calorimetry (DSC), an Instron ...
متن کاملSpider Silk Composites and Applications
In the past few years a number of reviews, books and journal articles featuring silks have been published. Silks are produced by over 41,000 species of spiders (class Arachnida) and by many insects (terrestrial and aquatic), particularly in the order Lepidoptera (Foelix, 1996); they are defined as externally spun fibrous material generated from protein secretions. The cocoon silk from the domes...
