Latest Patents

Yuming Wu holds two notable patents that showcase his expertise in the preparation of polyvinylidene fluoride (PVDF)-based pyroelectric polymer films. The first patent describes a one-step solution casting method for preparing PVDF-based films. This method involves treating a substrate with a hydrophilic reagent to create a hydrophilically-modified surface. The organic solution of PVDF is then cast onto this substrate, resulting in a film that exhibits pyroelectricity without the need for stretching or poling post-treatment. The self-polarization of the film is attributed to a hydrogen bond-induced layer-by-layer electrostatic self-assembly growth mechanism. This method is characterized by its simplicity, low cost, and high efficiency, allowing for the production of thick, large-area films with smooth morphology.

The second patent outlines a method for preparing pyroelectric polymer films through a combined process of solution casting and uniaxial stretching. In this approach, the film is first prepared by solution casting and then subjected to uniaxial stretching while in a semi-cured state. This technique enables a larger stretching ratio at lower temperatures, resulting in films that possess excellent pyroelectric performance and smoother surfaces with fewer defects.
