Accelerated weathering effects on poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) and PHBV/TiO2 nanocomposites
(
MDPI AG
, 2020 , Article)
The effect of accelerated weathering on poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) and PHBV-based nanocomposites with rutile titanium (IV) dioxide (PHBV/TiO2) was investigated. The accelerated weathering test ...
Effects of rutile-TiO2 nanoparticles on accelerated weathering degradation of poly(Lactic Acid)
(
MDPI AG
, 2020 , Article)
The effect of accelerated weathering on poly(lactic acid) (PLA) and a PLA nanocomposite with rutile titanium (IV) dioxide (rutile-TiO2) was investigated. The accelerated weathering test applied consecutive steps of ultraviolet ...
Effect of plasma treatment on accelerated pla degradation
(
BME-PT and GTE
, 2021 , Article)
Poly(lactic acid) (PLA) has been found to be important in various applications, such as in the medical, pharma-ceutical, and packaging industries. However, the long-term associated degradation process of PLA is a limiting ...
Generation of photo charge in poly(ethyleneimine)-TiO2-anthocyanin modified papers conditioned at different humidities
(
Elsevier Ltd
, 2018 , Article)
The article describes the influence of humidity on the surface photodielectric properties of papers prepared from poly(ethyleneimine)-TiO2 nanoparticles-anthocyanin modified cellulose fibres. The anthocyanins were extracted ...
Nanofibrous alginate membrane coated with cellulose nanowhiskers for water purification
(
Springer Verlag
, 2018 , Article)
The aim of this study was to develop a filtration membrane based on two-layered nanoscale alginate nanofibres reinforced with maize cellulose nanowhiskers (diameter between 3 and 12 nm). Reinforcing of the membrane with ...
Influence of TiO2 nanoparticles on the crystallization behaviour and tensile properties of PLA/TiO2, PCL/TiO2 and PLA/PCL/TiO2 nanocomposites.
(
Springer Verlag
, 2018 , Article)
This paper investigated the influence of TiO2 nanoparticles on the morphologies, as well as crystallization behaviour and kinetics, of neat PLA and PCL, and of these polymers in different PLA/PCL blends. We used transmission ...
Magnetic solid phase extraction (MSPE) for chromatographic separation of carbamates.
(
Wiley
, 2018 , Article)
Magnetic solid phase extraction particles (MSPE) were produced using magnetite nanoparticles with diameters between 9 and 13 nm as nucleating agent. The produced particles with magnetite cores were smaller, and more irregular ...
Charge-trapping capability and AC conductivity at different humidities of poly(ethyleneimine)-TiO2-anthocyanin modified cellulose fibres.
(
Springer Verlag
, 2018 , Article)
Modified cellulose materials are finding increasing application in electronics, because of the need for more environmental-friendly electronic circuits. The papers prepared from poly(ethyleneimine)–TiO2–anthocyanin-modified ...
Morphology and property changes in PLA/PHBV blends as function of blend composition
(
Springer Netherlands
, 2018 , Article)
PLA/PHBV blends were prepared by melt mixing. The morphology and physical properties of the blends and neat polymers were investigated. Scanning electron microscopy (SEM) studies provided evidence of interfacial cavities ...
The effect of expanded graphite on the thermal stability, latent heat, and flammability properties of EVA/wax phase change blends
(
John Wiley & Sons, Ltd
, 2015 , Article)
This article reports on the morphology, melting and crystallization behavior, thermal stability, flammability and thermal conductivity of shape-stabilized phase-change materials (PCM) for thermal energy storage, based on ...
