Polyethylene-Based Nanocomposite Films: Structure/Properties Relationship
Polyethylene (PE) is the most used thermoplastic commodity as a consequence of its convenient cost-processing-performance relationship and it can be used in the form of films for food, goods and farming packaging. On the ...
Low-density polyethylene films incorporated with silver nanoparticles to promote antimicrobial efficiency in food packaging
Technological innovations in packaging are intended to prevent microbiological contaminations for ensuring food safety and preservation. In this context, researchers have investigated the antimicrobial effect of low-density ...
Simple and economical CALB/polyethylene/aluminum biocatalyst for fatty acid esterification
(John Wiley & Sons Ltd, 2017-09-19)
Candida antarctica lipase B was immobilized for the first time (at the author's knowledge) onto linear low density polyethylene (LLDPE) films. Polymer films were previously bonded to a commercial aluminum sheet using a ...
Nanocomposites-Based Polyolefins as Alternative to Improve Barrier Properties
(John Wiley & Sons IncHobokenEUA, 2010)
Comparison between different conditions of the chemical polymerization of polyaniline on top of PET films
Composites produced during the in situ chemical polymerization of aniline on top of a poly(ethylene terephthalate) (PET) film, in different conditions, were studied by open-circuit potential (Voc), ultraviolet-visible, and ...
The assembly of dialkyldimethylammonium bromide cationic lipids as vesicles or monolayers in presence of poly(ethylene glycol)
(Elsevier B.V., 2015-08-10)
The interaction between polymer and lipid vesicles may result in stabilization and formation of highly ordered networks, which can mimic biological membranes and be used as drug delivery system. Here we used differential ...
Polyethylene film incorporation into the horticultural soil of small periurban production units in Argentina
Horticulture makes intensive use of soil and extensive use of polyethylene (PE) sheeting and pesticides, producing an environment where the dynamics between soil and plastics can affect pesticide fate. We have determined ...
Influência do tipo de coleta (comum ou seletiva) na reciclagem de filmes de poliolefinas pós-consumo
(Associação Brasileira de Polímeros, 2008-01-01)
Filmes de polipropileno (PP) e de polietilenos de alta (HDPE) e baixa densidades (LDPE) foram estudados avaliando-se a presença de impurezas e o efluente da lavagem de seus resíduos provenientes tanto de coleta comum ...
Transparent nanostructured cellulose acetate films based on the self assembly of PEO-b-PPO-b-PEO block copolymer
In this study fabrication and characterization of transparent nanostructured composite films based on cellulose triacetate (CTA) and poly(ethylene oxide)-b-poly(propylene oxide)-b-poly(ethylene oxide) (EPE) triblock copolymer ...
