Single and hybrid organoclay-filled PLA nanocomposites: mechanical properties, viscoelastic behavior and fracture toughening mechanism
(Wiley, 2021-04-04)
Article
Restricted access - publisher's policyPoly (lactic acid) (PLA) nanocomposites based on single and hybrid organic-modified montmorillonites were previously studied in terms of their morphologi-cal, thermal and fire performance. As surfactants of the organoclays ... -
Antimicrobial activity and gc-ms profile of copaiba oil for incorporation into xanthosoma mafaffa schott starch-based films
(Multidisciplinary Digital Publishing Institute (MDPI), 2020-12-01)
Article
Open AccessThe present study evaluated the effect of the incorporation of copaiba oil, in direct and in microencapsulated form, into films based on Xanthosoma mafaffa Schott starch. Initially, the characterization of copaiba oil by ... -
The effect of microcellular structure on the dynamic mechanical thermal properties of high-performance nanocomposite foams made of graphene nanoplatelets-filled polysulfone
(Multidisciplinary Digital Publishing Institute (MDPI), 2021-01-29)
Article
Open AccessPolysulfone nanocomposite foams containing variable amounts of graphene nanoplatelets (0–10 wt%) were prepared by water vapor-induced phase separation (WVIPS) and supercritical CO2 (scCO2) dissolution. WVIPS foams with two ... -
Influence of acrylic acid and tert-dodecyl mercaptan in the adhesive performance of water-based acrylic pressure-sensitive adhesives
(Multidisciplinary Digital Publishing Institute (MDPI), 2020-12-01)
Article
Open AccessCurrently, pressure-sensitive adhesives (PSA) are used in more than 80% of all labels in the market today. They do not require any heat, solvent, or water to activate: It only takes light pressure to apply them to a product ... -
Methods of incorporating plant-derived bioactive compounds into films made with agro-based polymers for application as food packaging: A brief review
(Multidisciplinary Digital Publishing Institute (MDPI), 2020-11-01)
Article
Open AccessPlastic, usually derived from non-renewable sources, is among the most used materials in food packaging. Despite its barrier properties, plastic packaging has a recycling rate below the ideal and its accumulation in the ... -
Development of inorganic particle-filled polypropylene/high density polyethylene membranes via multilayer co-extrusion and stretching
(Multidisciplinary Digital Publishing Institute (MDPI), 2021-01-19)
Article
Open AccessThis work is made to ascertain the effects of mineral fillers, namely calcium carbonate and talc, on the morphology and properties of multilayer polypropylene (PP)/high-density polyethylene (HDPE) porous membranes. Multilayer ... -
Electrical conduction behavior of high-performance microcellular nanocomposites made of graphene nanoplatelet-filled polysulfone
(2020-12-04)
Article
Open AccessGraphene nanoplatelet (GnP)-filled polysulfone (PSU) cellular nanocomposites, prepared by two different methods—namely, water vapor-induced phase separation (WVIPS) and supercritical CO2 dissolution (scCO2) foaming—were ... -
Extraction and characterization of starches from pigmented rice
(2020-08-01)
Article
Restricted access - publisher's policyThe aim of this work was to extract and characterize starch from three varieties of pigmented rice (named white, red and black), preserving the bioactive compounds. The extraction yield was 44.0%, 47.0% and 35.7%, respectively. ... -
