“…For polymer porous materials, the improvement of their heatinsulating performance have been mainly achieved by refining the pore structures. 16,24,[28][29][30][31][32][33] Moreover, it also can decrease their thermal conductivity by controlling their foam density. 34 For example, the study by Lei et al indicated that the thermal conductivity of PF with mean pore size of 800 nm and foam density of 120 kg/m 3 can achieve 0.028 W/mK at 293 K. 28 Song et al reported that the thermal conductivity of modified PF with 1.0 wt % multiwalled carbon nanotubes with 65.3 kg/m 3 is 0.058 W/mK at room temperature.…”

In this work, titanium nitride (TiN) nanoparticles were employed to achieve enhanced thermal insulation and flame retardance of phenolic foam (PF)/TiN nanocomposites (PFTNs) via in situ polymerization. The morphologies of PFTNs were observed by scanning electron microscope and the images showed that the PFTNs have more uniform cell morphologies compared with pure PF. Thermal insulating properties of PFTNs were evaluated by thermal conductivity tests. The introduction of TiN obviously decreased the thermal conductivities of PF over a wide temperature range (220 to 60 8C). Significantly, the thermal conductivity of PFTNs gradually decreased as the temperature increased from 30 to 60 8C, showing a contrary tendency with that of pure PF. Moreover, the thermal stability and flame-retardant properties of PFTNs were estimated by thermogravimetric analysis (TGA), UL-94 vertical burning and limited oxygen index (LOI) tests, respectively. The TGA and LOI results indicated that PFTNs possess enhanced thermal stabilities and fireretardant performances with respect to the virgin PF.

Current policies addressing the energy efficiency of building constructions urge planners and manufacturers to properly design the edifice envelope which has to be conceived with a view to both optimizing its thermal performances and complying with the local and national regulations. To achieve this target, for the last few years, researchers involved in building industry have been devising new structures able to realize proper levels of envelope thermal insulation, also employing materials characterized by low environmental impacts owing to their natural origin (such as vegetal fibers) or because derived from industrial/ agricultural process waste. As a contribution to this topic, the purpose of this paper is to assess the insulation features of various structures made up of totally natural and biocompatible materials, in order to try to single out the optimal configurations. The studied mixtures, as a matter of fact, consist of a natural binder (such as hydraulic lime NHL 3.5) and a biocompatible inert material (such as dry platanus acerifolia fruit, natural cork, etc.) with various mass ratio compositions. The measured parameter is the thermal conductivity and the method used is the one stated by the ASTM C518 -04 Standard, which employs a heat flow meter apparatus establishing steady state one-dimensional heat flux through a test specimen between two parallel plates at constant but different temperatures. Fourier's law of heat conduction is, hence, used to calculate thermal conductivity of the specimen.
