Modified polymer blends demonstrated the desirable properties and performance suitable for various applications. In the present investigation, we prepared the blends of crystalline Polyvinylidene fluoride (PVDF)/ with amorphous Polysulfone (PSF) by a solution technique. We have foreseen the miscibility of the PVDF/PSF polymer system by an optical polarizing microscope. The electrical quality factor (Q) of these polymer blends demonstrated increased quality magnitude with the shift in resonance frequency (\(f_{0}\)) and bandwidth (B.W.) confirmed by an impedance analyzer. The influence of the temperature on the quality factor was studied across the temperature scale (30 to 150 ∘C). This investigation was feasible for the development of a new class of polymer blends deployable for electronics and shielding applications.

改进了电子应用中聚合物共混物的阻尼阻尼振荡器特性
改性的聚合物共混物显示出适合各种应用的理想性能和性能。在本研究中,我们通过溶液技术制备了结晶聚偏二氟乙烯(PVDF)/与无定形聚砜(PSF)的共混物。我们已经通过光学偏振显微镜预见了PVDF / PSF聚合物系统的可混溶性。这些聚合物共混物的电品质因数(Q)随共振频率(\(f_ {0} \))和带宽(BW)的变化(由阻抗分析仪确认)而显示出更高的品质等级。在整个温度范围(30至150∘)中研究了温度对品质因数的影响 C)。这项研究对于开发可用于电子和屏蔽应用的新型聚合物共混物是可行的。
