Aliphatic poly(carbonatediol)-polyurethane (APCD-PU) series were synthesized using a fixed isophorone diisocyanate (IPDI) and two types of APCD, which fell into the different molecular weight and with/without the pendant alkyl groups. Graphene oxide (GO) sheets were chemically grafted with allophanate-functionalized APCD-PUs. Mechanical and physical properties of APCD-PU-g-GO were evaluated by UTM, DSC, UV-spectrometer, and WVTR analysis. The transmittance of individual APCD-PU-g-GO was gradually enhanced from 77.82% to 92.15%. Water vapor permeability values of APCD-PU-g-GO series varied from 200 to 36 g/m2∙day. |
