Natural fibers are widely used as plastic composite material reinforcements.In this work, composites of postconsumer high-density polyethylene (HDPE) reinforced with sisal were prepared.PE and chemically modified to improve their compatibilities, try increase the hydrophobic character fiber hydrophilic HDPE.Sisal was mercerized a NaOH solution acetylated PE oxidized KMnO4 solution.The characterized by Fourier Transformed Infrared Spectroscopy (FTIR) 13 C Nuclear Magnetic Resonance ( NMR).The...
Polyethylene terephthalate (PET) is a very stable polymer widely used in the modern world. Due to its stability, this can remain environment for several years before complete degradation. The glycolysis reaction of PET has emerged as green approach obtain monomer, thus avoiding such environmental problems and adding value waste. In work, waste was depolymerized by using ultrasmall cobalt nanoparticles (1.5 wt %) catalyst production bis-2-hydroxyethyl (BHET). A capping agent (tannic acid, TA)...
This work aims at the production and characterization of promissory food packaging films based on chitosan (CS), zein (ZN), poly (vinyl alcohol) (PVA). CS ZN are biodegradable, biocompatible, extracting from natural-sources renewable. Although PVA is a synthetic polymer, it also considered biocompatible present water-solubility. From binary ternary macromolecule mixtures CS/ZN/PVA, were obtained solvent-free. In this facet, extrusion mixture following by hot compression to acquire films' The...
A hybrid material on the carbon paste electrode exhibited a greater electroactivity for determination of an endocrine disruptor.
Poly(phenylsilsesquioxane) (PPSQ) polymers that were obtained from different synthetic routes comparatively studied. The characterized by infrared and solid-state 29Si NMR spectroscopies. According to the results of X-ray diffraction thermogravimetric analyses, materials richest in silanol showed a less organized network lower weight loss temperature. morphology products was influenced preparation conditions. PPSQ, with rich spherical particles, achieved an n-hexadecyltrimethylammonium...
In this work, sugarcane bagasse fibers were used as filler in composites having recycled high‐density polyethylene (PEr) matrix. Because of the poor interaction between surface and PEr, was chemically modified. This modification consists washing with water at 80°C, a mercerization process using sodium hydroxide acetylation reaction acetic anhydride. The chemical characterized by Fourier transform infrared–horizontal attenuated total reflectance (FTIR‐HATR) 13 C nuclear magnetic resonance...
