                 Abstract: Plant oil-based  waterborne  polyurethanes  were synthesized  from castor oil and hydroxyl-
                 terminated polyether modified polysiloxane (PEPSO). During the synthesis of prepolymer, different amount
                 of double-decker octaphenylsilsesquioxanetetraol  (DDSQ-4OH) was introduced into the waterborne
                 polyurethane main chains, which led to a series of PEPSO/DDSQ-4OH modified waterborne polyurethane
                 nanocomposites with different amount of DDSQ-4OH (WPU-15, WPU-15-2, WPU-15-4, WPU-15-6 and
                                 1
                 WPU-15-8). FTIR,  HNMR, TGA, SEM, TEM and particle size analyzer were used to characterize these
                 materials. The influence of nano-particle DDSQ-4OH on  the thermal stability, hydrophobicity and
                 mechanical properties of  polyurethane materials was  discussed.  TGA results showed that the initial
                 decomposition temperature (T 5%) of the composite containing 8% (based on mole of the chain extender
                 ethylenediamine, as the  below)  DDSQ-4OH increased by 22.5  ℃ compared with WPU  which didn't
                 contain DDSQ-4OH. Static contact angle test and SEM results revealed that when the DDSQ-4OH amount
                 increased, the hydrophobicity of the obtained polyurethanes was improved, and the static contact angle of
