چکیده انگلیسی
The pyroelectricity of Poly vinylidene fluoride (PVDF) is improved by incorporation inclusions in it. The best inclusions properties (volume fraction, dielectric constant, pyroelectric coefficient, molecular weight and density) were determined, which increase the pyroelectrical coefficient and dipole moment of PVDF. For very small volume fraction (<0.035) and dielectric constant of nonferroelectric inclusion is slightly smaller than PVDF, the pyroelectric coefficient of PVDF composite increases. For pyroelectrical inclusion, the pyroelectric coefficient of PVDF composite can increase by three states. It increases for very small volume fraction (<0.035), very low pyroelectric coefficient and dielectric constant of pyroelectrical inclusion is slightly smaller than PVDF. In addition, it increases for very small volume fraction (<0.035), high pyroelectric coefficient and dielectric constant of pyroelectrical inclusion is slightly higher than PVDF. Beside it increase for high pyroelectric coefficient and very small dielectric constant of pyroelectrical inclusion. The maximum value of the dipole moment is obtained under the following conditions: very small volume fraction (<0.035), both inclusion density and dielectric constant is smaller than PVDF, and inclusion molecular weight is higher than PVDF, or also under those following conditions: high volume fraction, inclusion density is smaller than PVDF and both molecular weight and dielectric constant of inclusion are higher than PVDF.
