Title: Innovations of Yangjian Dong
Introduction
Yangjian Dong is a notable inventor based in Mianyang, China. He has made significant contributions to the field of polymer science, holding a total of 6 patents. His work focuses on methods that enhance the efficiency of polymer processing and recovery.
Latest Patents
One of his latest patents is a method for polymer precipitation. This method involves adding a precipitation agent into a first suspension containing a polymer and an aqueous solvent. The polymer comprises a copolymer with structural units derived from both an acid group-containing monomer and a hydrophobic group-containing monomer. This innovative method initiates bond disruption between the polymer and the aqueous solvent, leading to a structural transformation that facilitates the precipitation of the polymer. It effectively circumvents complex separation processes and contamination, allowing for excellent material recovery within a short time frame. An application of this method is found in the precipitation of a polymeric binder in battery electrodes.
Another significant patent by Yangjian Dong is a method for composite delamination. This method involves immersing a composite into a delamination solution, where the composite consists of a substrate and a polymeric binder coating. The use of a weak acid-containing delamination solution allows for complete and efficient delamination of the composite. This method also avoids complex separation processes and contamination, ensuring excellent material recovery. An application of this method is in the delamination of electrodes for batteries.
