Noble-gas-infused neoprene closed-cell foams achieving ultra-low thermal conductivity fabrics

Closed cell foams are widely used as protective garments in extreme environments. This article studied the use of neoprene-based materials in wetsuits by developing a strategy for reducing the thermal conductivity of a flexible, closed cell polychloropene foam. The thermal conductivities of the charged and unmodified neoprene foams were measured using the transient plane source (TPS) method with the TPS thermal conductivity meter. It was found that a wetsuit made ...

Hybridizing graphene aerogel into three-dimensional graphene foam for high-performance composite phase change materials

The present study aims at encapsulating hybrid graphene aerogel (HGA) into 3D graphene foam (GF) to fabricate high-performance composite phase change materials (PCM). Using the chemical vapor deposition (CVD) technique, a 3D hybrid GF/HGA (GH) microstructure was formed to create PW/GH composite PCMs. Thermal conductivity of PW/GH composite PCMs increased due to optimized 3D GH hybrid microstructure....

Biobased foams from condensed tannin extracts from Norway spruce (Picea abies) bark

Research found tannins have been successful as monomers to produce organic foams with superior properties for thermal insulation. Norway spruce (Picea abies) tannins were extracted and used to prepare tannin/furanic foams. Thermal conductivity measurements were taken by transient plane source method. Thermal conductivity performance improved with higher closed-cell content in the foam....

Effect of vinyl-modified silica and raw silica particles on the properties of as-prepared polymer-silica nanocomposite foams

This research studied the effect of the addition of vinyl-modified silica and raw silica additions to polymer-silica nanocomposite foams. Extensive physical property characterization was undertaken after their addition to quantify their influence. TEM found that silica particles added through the vinyl-modified silica dispersed better than the raw silica. This created foams with a higher density and smaller cell size. A slight reduction in the thermal conductivity after the additions was ...

Tannin/furanic foams without blowing agents and formaldehyde

The purpose of this study was to produce an environmentally friendly foam using tannins, that did not contain any formaldehyde or blowing agents. Two experimental tannin foams were compared to two conventional foams, one containing both formaldehyde and blowing agents, and the other containing only a blowing agent. A variety of physical properties were assessed to determine if the new green formulation would be an appropriate replacement, this included thermal ...
