Dynamic Characteristics of Inkjet-printed Thin Films of Nanosilver Suspensions on Different Kinds of Substrates

The dynamic properties of inkjet-printed thin films on flexible polyimide (PI), glass, wafer substrates were investigated using the vibration analysis adopting wave approach. In order to fabricate the test specimens, the Ag nano-particle suspension was inkjet-printed on thin films. The beams were used as the cantilever beam in the vibration test. From the base-excited response of the beam, the frequency-dependent bending stiffness and loss factor were obtained, which were used to calculate Young?s modulus and loss factor of the inkjet-printed thin films. The influence of film material and film thickness on the dynamic properties was investigated and the nano-indentation test was also performed to compare results from each test. The proposed method enables the direct determination of the dynamic characteristics of thin films without damaging the thin films during removal of the substrate from the film.��� ��������� ��������� ��������� ������������(10848)��� ��������� ������ ��������� ������������ ������ ������ ������������
