Professor Zhong Linxin of South China University of Technology made a report entitled "Paper-based flexible supercapacitor electrode". The functional properties and application potential of various paper-based flexible supercapacitor electrode materials, such as N-doped carbon sheet/polyaniline (PANI) nanocellulosic fiber flexible composite materials, ultra-high capacity foldable supercapacitor electrode materials, electrostatic self-assembly paper-based flexible composite electrode materials, were introduced.

Professor Nie Shuangxi of Guangxi University, entitled "Progress in Research and Application of Advanced Cellulose functional Materials", introduced the research progress and application prospect of advanced cellulose functional materials in energy collection and conversion, pulse direct current conversion, and water collection, and analyzed the research on molecular regulation, structural design, structure-activity relationship and other aspects of cellulose functional materials.

Professor Shen Wei of Monash University in Australia published a report entitled "Improvement Strategy of Paper-based analysis Device in colorimetric Performance and practical Application", summarizing the working principle of paper-based colorimetric analyzer (PADs) and the strategy of improving colorimetric performance and the design scheme of improving portability. In particular, the principle of controlling liquid-paper interaction based on PADs design to increase color saturation is discussed, and the image acquisition technology and image processing algorithm related to color accuracy and sensitivity are introduced in detail, which will help to develop and design PADs with higher sensitivity and portability.

Dr. Zhang Xue from China Pulp and Paper Research Institute published a report entitled "Research Progress on water Vapor barrier Properties of Paper-based materials". Starting from the multi-layered structure of paper-based materials, the transport mechanism of water vapor in the multi-layered structure of paper-based materials was introduced, and the difficulties of water vapor barrier were analyzed. The research progress of 3D internal structure control and surface structure modification to improve the water vapor barrier properties of paper based materials is introduced. The water vapor barrier properties of superhydrophobic paper based materials are evaluated.

Innovative pulp multiple transformation

"Paper instead of plastic" green development

Ms. Beatriz Santucci, Senior Researcher at Susanuno, presented a report on the topic "Development of Eucalyptus sulphate pulp as an alternative pulp for the manufacture of environmentally friendly packaging products", noting that Susanuno produces approximately 10.9 million tons of eucalyptus commercial pulp per year, with sustainable management models and production processes. Beatriz Santucci also mentioned that bleached hardwood kraft pulp has excellent physical properties and cost competitiveness, and its market demand will be further expanded in the future, and can replace other fiber raw materials, to achieve the goal of "fiber instead of fiber."

Professor Shen Jing of Northeast Forestry University, with the title of "Fiber source papermaking additives and technological innovation of" Paper instead of plastic ", proposed a research scheme to transform pulp fibers into multiple products by means of molding by comparing the cross-characteristics of plastics and papermaking fields. Professor Shen Jing said that the use of fiber source green paper additives can improve the porosity, wet strength, barrier properties of paper, etc., to achieve the development goal of "replacing plastic with paper".

Lucas Ornelas Jacinto, a senior researcher at Cunio, presented a report entitled "Eucalyptus pulp for pulp molding", presenting a strategy to promote sustainable packaging through the "pulp molding" of eucalyptus fibres. Eucalyptus wood fiber has low beating energy consumption, stable performance in the molding process, has good compressive and torsional properties, is suitable for pulp molding good material. Lucas said that at present, Shuzhunuo has jointly developed and evaluated the molding of 100% eucalyptus wood fiber pulp with partners in China and Sweden, and carried out industrial trial production.
