Electrical and dielectric properties of poly (methyl methacrylate) thin films: article / Khairizal Mohamad

This work investigated the behavior of poly (methyl methacrylate) (PMMA) as dielectric films. The PMMA tllms u'ere deposited on the glass subsfiates using spin coating technique. The PMMA concenfiations were varied from 0.3,0.6.0.9 to 1.2 g. The electrical properties results is indicated when PMMA concentration is increased. the resistivity were also increased from 3.59 O.cm to 1.06 x 107 C).cm and it became more insulative at the high concentration of PMMA. For dielectric properties result, the dielectric constants are in range 0.35 lo 2.72 at the frequency of I MHz. Meanwhile the capacitance shows the value average of the PMMA concentration for capacitance in a range at -x l0-r1'F at the frequency of I MHz.
