Latest Patents

One of Wu's latest patents is focused on an acrylate oligomer and its preparation method. This invention describes an acrylate oligomer obtained through the reaction of isocyanate group-terminated oligomer and formate-terminated ethylene glycol methacrylate. The resulting acrylate oligomer can undergo photocuring, allowing for modifications in its molecular structure and cross-linking density through specific post-processing techniques. The final material exhibits lower water absorption and glass transition temperature due to the properties of the formate component formed after heat treatment.

Another notable patent involves a method for controlling stress distribution in materials. This method includes preparing a crosslinked polymer with reversible exchange bonds, applying external force to induce strain, and selectively heating specific regions of the polymer while maintaining the strain. This innovative approach allows for the control and utilization of internal stresses, which are typically viewed as detrimental. Additionally, the invention provides a method for reading information in a polarized light field, where the treated crosslinked polymer remains transparent under natural light, ensuring concealment of the information.
