Article
Open AccessEn este trabajo se han desarrollado diferentes aerogeles con baja flamabilidad basados en la combinación de biopolimeros renovables y montmorillonta (MMT). Los compuestos fueron hechos usando agua como solvente y siguiendo ... -
Using the small punch test to analyse the influence of ultraviolet radiation on the mechanical behaviour of recycled polyethylene terephthalate
(2019-10-01)
Article
Open AccessThe aim of this work is to evaluate the feasibility of small punch test as a tool for analysing the mechanical response of small plastic parts or specimens. Here, the small punch test was used to study the possible influence ... -
Synthesis and Properties ofWater-Based Acrylic Adhesives with a Variable Ratio of 2-Ethylhexyl Acrylate and n-Butyl Acrylate for Application in Glass Bottle Labels
(Multidisciplinary Digital Publishing Institute (MDPI), 2020-02-12)
Article
Open AccessA series of Pressure-Sensitive Adhesives (PSAs) with different soft monomer compositions were prepared by using emulsion polymerization. The monomers used were acrylic acid (AA), n-butyl acrylate (n-BA) and 2-ethylhexyl ... -
Effect of filler content, size, aspect ratio and morphology on thermal, morphological and permeability properties of porous talc filled—Polypropylene obtained through MEAUS process
(2018-12)
Article
Open AccessSeveral commercial grades of talc were selected to develop polypropylene based microporous membranes through MEAUS process (melt extrusion—annealing—uniaxial strain). Talc commercial grades differed in particle size, aspect ... -
Effects of graphene nanoplatelets and cellular structure on the thermal conductivity of polysulfone nanocomposite foams
(Multidisciplinary Digital Publishing Institute (MDPI), 2020-01)
Article
Open AccessPolysulfone (PSU) foams containing 0–10 wt% graphene nanoplatelets (GnP) were prepared using two foaming methods. Alongside the analysis of the cellular structure, their thermal conductivity was measured and analyzed. The ... -

Recent advances in carbon-based polymer nanocomposites for electromagnetic interference shielding
(2019-06)
Article
Restricted access - publisher's policyCarbon-based nanoparticles have recently generated a great attention, as they could create polymer nanocomposites with enhanced transport properties, overcoming some limitations of electrically-conductive polymers for high ... -
Polyetherimide foams filled with low content of graphene nanoplatelets prepared by scCO2 dissolution
(Multidisciplinary Digital Publishing Institute (MDPI), 2019-02-13)
Article
Open AccessPolyetherimide (PEI) foams with graphene nanoplatelets (GnP) were prepared by supercritical carbon dioxide (scCO2) dissolution. Foam precursors were prepared by melt-mixing PEI with variable amounts of ultrasonicated GnP ...
