In order to investigate the impact of drawing ratio of inorganic nano-hybrid polyamide three-layer composite films,the stretched composite films with different draw ratio were prepared by drawing partial imido polyamide film and then through the ring closing reaction in the high temperature,and the draw ratio was 0% ,2% , 4% ,6% ,8% ,10% ,12% ,14% etc. Under the same conditions,we made different draw ratio of three-layer composite film tensile test with the electronic universal material testing machine. The results show: doped inorganic nanometer oxide made PI film elastic modulus increase slightly,the tensile strength and elongation at break decrease obviously,...
