دراسة تأثير دقائق أوكسيد التيتانيوم Tio2 الأنبوبي النانوية على متراكبات بوليميرية جديدة

الملخص EN

Ananopartical of titaniumdioxides prepared .

the partical was diagnosed by usage of many techniques ; like infrared spectrum (FT- IR) , Scanner electronic microscope (SEM) and atomic force microscope (AFM) .

Also have been prepared two types of polymer : (PAPA) and (PMUT) .

the two polymers are diagnosed by infrared spectrum .

these two polymers are compoundel with "poly vinylalcohol " (PVA) .

the electrical characteristics , and are studied after doping by titanium dioxide.the composite films of polymer (PAPA) and nanotube of titanium dioxide show that magnitude of the real and imaginary dielectric constant was reduction in the magnitude value from (24.9 – 7.5)with low hesitations the imaginary dielectric constant value is high ,there for it is not useful to storing the electrical energy .

the composite films of polymer (PMUT) with nanoparticles of titanium dioxide , have areal dielectric constant value of (955) , and imaginary dielectric constant value 0f (84) , the high distinction between real and imaginary dielectric constant , sin manufacture of the electrical capacities , because it has capability to storing of electrical energy .

The relaxing tense with low hesitations (10000 – 20000 HZ.Sec), and these low hesitations help in the age of these films in manufacturing of electrical devices.
