Abstract:
Blends with composition 50/50(wt/wt%)poly(vinyl)alcohol (PVA)/poly(vinyl) pyrrolidone (PVP) doped with different weight ratios from benzoxazinone derivative (BZ) were prepared by casting solution technique. The optical absorption was recorded at room temperature in the wavelength range of 190-1100nm. Tauc's plots revealed direct allowed transition with optical band gap, Eopt, of 5.20eV for blend film. Under addition of benzoxazinone, the optical energy value decreased until 2.60eV for 12wt% BZ blend system. Optical parameters such as refractive index, dielectric constant, dielectric loss and color constants were determined. Benzoxazinone molecules have a significant effect on optical parameters.

Static Friction
For example, consider a scenario where a truck is connected to a car by a rope, ready to tow it along a road. When no external force is applied by the truck, the car remains stationary and is said to be in static equilibrium. In this case, the forces acting on the car, such as gravity and the...
