Title: Peng Yang: Innovator in Polyimide Precursor and Laccase Production
Introduction
Peng Yang is a notable inventor based in Jinan, China. He has made significant contributions to the field of materials science and biotechnology, holding a total of 2 patents. His work focuses on innovative methods for producing advanced materials and enzymes.
Latest Patents
Peng Yang's latest patents include a self-sensitizing negative polyimide precursor and a method for preparing the same. This invention utilizes 4,4'-dinitro-1,1′-biphenyl-2,2′-dicarboxylic acid as a starting material, which undergoes an acylation reaction with thionyl chloride to produce compound 1. This compound is then esterified with 2-hydroxyethyl methacrylate to yield compound 2. The nitro groups in compound 2 are reduced to amino groups, leading to the formation of an intermediate for the self-sensitizing negative polyimide precursor. The polymerization of this intermediate with 3,3′,4,4′-benzophenone tetracarboxylic dianhydride results in a polyamic acid. The unique properties of this precursor allow it to act as a photoinitiator under ultraviolet irradiation, enhancing the exposure sensitivity of the resin.
Another significant patent involves a method for producing laccase through liquid fermentation. This method includes inoculating strains into a PD liquid fermentation medium, followed by a series of steps that significantly increase the output of laccase compared to traditional methods.
