Polycarbonate foams reinforced with 0,5 wt% of graphene were obtained by firstly melt-mixing the polycarbonate and graphene in an internal mixer, compression-moulding the melt-compounded grinded material and lastly dissolving ...

A novel technique to determine in situ the free expansion kinetics of chemically foamed thermoplastic foams, so-called optical expandometry, is presented in this work. This technique is based on the camera monitoring ...

Closed-cell polycarbonate foams were prepared using a two-step foaming process, which consisted of the initial dissolution of supercritical CO2(scCO2) into PC foaming precursors and their later expansion by heating using ...

It is well known the relevance given to the study of heat transfer in polymer foams, as one of the main applications is as lightweight thermal insulating elements. Alongside some of the possible strategies for improving ...

Las espumas microcelulares poseen óptimas propiedades específicas que pueden ser ampliadas por incorporación de nanopartículas laminares y/o sustratos inorgánicos. Por ello, en el presente estudio se han preparado, por el ...

The preparation and characterization of cellulosic fibre-reinforced polypropylene composite foams is presented. The cellulose fibres were isolated from a barley straw obtained from local sources. They were compounded with ...

Polymer-based (nano)composite foams containing conductive (nano)fillers limit electromagnetic interference (EMI) pollution, and have been shown to act as good shielding materials in electronic devices. However, due to their ...

This article presents the analysis of the processing parameters influence on the foaming behavior and cellular structure of PP-montmorillonite foams. Polypropylene nanocomposites containing 5.0 phr of an organically- modified ...
