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.
