The Application of Thermal Building Nano-Insulation Materials Based on the Diffusivity Characteristic of Polyurethane Nanocomposite

Norayuni Azizi and Kamal Yusoh
Abstract—The paper aims to study diffusivity measurement of polyurethane (PU) nanocomposite with incorporation of montmorillonite nanoclay cloisite B30 (B30) prepared by solution intercalation method using chloroform as a solvent. The mixed compositions based on PU/B30 were analyzed according to the following weight percentage using 0.5%, 1%, 2% and 4% of montmorillonite nanoclay cloisite B30. The morphology of the samples was observed through Scanning Electron Microscopy (SEM) and Fourier Transform Infrared Spectrometer (FTIR). The observation of SEM showed PU/B30 is not miscible meanwhile FTIR revealed that the surface segregation of the montmorillonite nanoclay cloisite B30 had not affected in PU. Next, water permeability test was conducted using nitrogen gas with different pressures. The pristine PU shows the lowest time taken for both pressures and contrary to the PU nanocomposite. This is supported by water absorption test in which the PU nanocomposite absorbs more water rather than the pristine PU.

Index Terms—Polyurethane, insulation, mechanical characteristics, nanocomposite.
