摘要： Disclosed is a method for preparing a quantum rod/polymer fiber membrane by using electrospinning technique. The method comprises the following steps: (1) preparing a quantum rod solution; (2) preparing a polymer solution, and adding the quantum rod solution obtained in step (1) into the polymer solution so as to form an electrospinning precursor solution with a volume concentration of the quantum rods of 5%-80%; and (3) adding the electrospinning precursor solution into an electrospinning device, regulating the voltage of a generator and the receiving distance, and then performing electrospinning to prepare the quantum rod/polymer fiber membrane. By adjusting the concentration of the quantum rod solution and parameters in the electrospinning process, the method realizes directional arrangements of the quantum rods in the electrospinning process, thereby obtaining the quantum rod/polymer fiber membrane with high degree of polarization performance.
