On May 28, 2026, the Chinese Society of Instrumentation organized a panel of experts to convene a scientific and technological achievement appraisal meeting in Xi’an. The meeting appraised the project “Development and Application of Sensor Barrier Membrane Materials”, completed by the Institute of New Concept Sensors and Molecular Materials at Shaanxi Normal University. Following evaluation, the project was recognized as having reached an internationally leading level.

The Evaluation Committee is chaired by Academician Jiang Guibin of the Research Center for Eco-Environmental Sciences, Chinese Academy of Sciences, and comprises Academician Li Yongfang of CAS Institute of Chemistry, and Academician Bu Xianhe of Nankai University, General Cao Baoyu, former standing member of the Science and Technology Commission of the General Armaments Department, and Xi Hailin, Major General (Technical) researcher and director of the National Key Laboratory of Chemical, Biological, and Radiological Disaster Protection at the Institute of Chemical Defense, Academy of Military Sciences, as well as scholars and experts from AMS Institute of Chemical Defense, Southeast University, Tsinghua University, Northwestern Polytechnical University, Chongqing Chuanyi Automation Co., Ltd. and Xi'an Zhongxing Measurement and Control Co., Ltd.

Zhou Zhengchao, vice president of Shaanxi Normal University, and Li Jie, deputy director of CIS’s Department of Science, Technology, and Industrial Development, attended and delivered remarks. The meeting was chaired by Prof. Xue Dong, director of SNNU Department of Science and Technology.

At the meeting, the project team presented details of the project. Prof. Peng Junxia presented a report on the research and development process, Engineer Wang Pei presented a technical report on the project, and INCSMM vice dean Yang Xiaogang gave a report on the commercialization of the project’s outcomes.

Following questioning and discussion by the expert panel, the expert opinion concluded that: the STCPS barrier membrane material developed by the project team exhibits excellent overall performance, features an advanced manufacturing process, employs mild processing conditions, consumes low energy, and generates virtually no emissions of “three wastes”. Its raw materials and production equipment are sourced domestically, while stabilizers, additives, auxiliary materials, and quality control equipment were all independently developed, achieving dual innovation in both material types and preparation processes, and the overall technology has reached an internationally leading level.

The sensor barrier membrane material is a novel STCPS gas-liquid separation barrier membrane developed by Prof. Fang Yu’s team through a full-chain R&D process — from fundamental research to industrial applications — based on molecular gel technology. This technological achievement addresses the critical demand for high-performance gas-liquid separation barrier membranes in fields such as instrumentation, industrial equipment, public health, and public security. It has broken the monopoly held by foreign companies on high-end membrane materials technology, achieved large-scale production, and yielded significant socioeconomic benefits.

SNNU  School of Chemistry and Chemical Engineering Party Secretary Li Baoxin, dean Liu Chenghui and vice dean Ding Liping, S&T Department deputy director Qu Xinyun, as well as R&D engineers Wen Ruijuan and Luo Yanyan attended the meeting.
