Chemical modification of tannin/furanic rigid foams by isocyanates and polyurethanes

Polymeric tannin/furanic foams fortified with polyurethane (PUR) and 4,4’ diphenylmethane diisocyanate (pMDI) were prepared. The thermo-physical and mechanical properties of the produced foams were investigated experimentally.  It was found that since there were a number of active isocyanate groups on the PUR that was used, there was no difference in adding PUR or pMDI to the foams, and so only the results for pMDI were presented. It was found that ...

Thermal and electrical conductivity enhancement of graphite nanoplatelets on form-stable polyethylene glycol/polymethyl methacrylate composite phase change materials

Graphite nano-platelets (GnPs) were dispersed in polyethylene glycol (PEG)/polymethyl methacrylate (PMMA) to form a PEG/PMMA/GnPs composite organic form-stable phase change material. The effects of the incorporation of the GnPs on the morphological, structural, thermal, and electrical properties of the composite were then assessed. The experimental results indicated that the incorporation of the GnPs into the polymer increased the thermal and electrical conductivities, and it was concluded that ...

Effect of a micro-copolymer addition on the thermal conductivity of fly ash mortars

A Portland cement-based composite was made using a copolymer as one of the ingredients, and the potential of the composite for the production of non-structural masonry systems was evaluated. It was found that the composite had a similar performance to that of commercial cellular concretes. The results also indicated that the incorporation of fly ash into mortars decreased the thermal conductivity of the composite....

Incorporation of Phase Change Materials in Cementitious Systems via Fine Lightweight Aggregate

The incorporation of phase change materials (PCMs) into concrete bridge decks shows promise as a method of decreasing freeze/thaw cycling in bridge decks. The authors have conducted a study to determine the best carrier to be used for the incorporation of PCMs into concrete, as well as the effects of the incorporation of the carriers and PCMs on strength and thermal properties of mortars. Four different PCMs (PCM6, PT4, ...

Development of thermal insulating and sound absorbing agro-sourced materials from auto linked flax-tows

A rigid, self-supporting material derived from flax tow was prepared and its mechanical, thermal, hydrous, and acoustic properties were investigated. The study was performed to determine if this material would be a viable option for use as a biodegradable thermal and acoustic insulation in walls. The effect of flax-tow size after grinding on these properties was also investigated. It was determined that increasing the flax-tow size resulted in a reduction ...
