Then, the properties of abrasion resistance and oxygen gas barrier were investigated for the obtained films. The test results indicated that the abrasion resistance of PU covered with POSS (POSS MA2310) was slightly improved compared to the pure PU film. Furthermore, the oxygen transmission rate (OTR) of the POSS MA2310 covered film was decreased by up to one order of magnitude. However, since the POSS MA2310 layer was so rigid, the flexibility of PU was lost. On the other hand, the composite films with PU and POSS MA2310 maintained the flexibility and showed good abrasion resistance. Furthermore, abrasion track after the test was not observed by scanning electron microscope. OTR was also reduced by 75 % compared to the pure PU film. 䠉 11 䠉
