The present invention discloses a method for preparing stable 3D polymer objects with surface micro-nanostructures. The method includes the following steps: Step (1): Synthesizing a thermoset 2D polymer object with surface microstructures. The polymer network contains reversible exchangeable bonds. Step (2): deforming synthesized polymer to an arbitrary desired shape above the reshaping temperature with an external force applied. The permanent reshaping temperature falls in the range of 50-130° C. and external stress is held for 5 min-24 hours Step (3): after cooling, a permanent 3D polymer object with surface microstructure is obtained. Step (2-3) can be repeated for many cycles and the 2D polymer object can be arbitrarily and cumulatively deformed to get a complex 3D structures. The polymer networks contain reversible exchangeable bonds and bond exchange catalysts in the present invention. The method disclosed in present invention is simple and efficient for preparing complex 3D polymer objects with surface micro-nanostructures.

Принадлежит:

The invention discloses a probe impedance matching method which comprises the following steps: a probe semi-finished product with an initial impedance value is arranged, and comprises a grounded layer, a substrate and a probe layer, and the grounded layer and the probe layer are separated from the substrate in an insulating manner; and then, a dielectric layer with a special dielectric constant is formed on the substrate and the probe layer so as to reduce the initial impedance value to a target impedance value. Therefore, the probe has required characteristic impedance by virtue of the probe impedance matching method.

Method for chemical upcycling of resins containing ester bonds

Номер: US20230357533A1
Автор: Jingjun Wu, Ning Zheng, Tao Xie, Zenghe Liu, Zizheng Fang
Принадлежит: Zhejiang University ZJU

A method for chemical upcycling of the resins containing ester bonds is described herein. The method comprises two steps: (1) The resins dissolved into a catalyst-solvent system via a network fragmentation strategy to generate non-crosslinked polymer fragment mixture with functional groups. (2) After introducing additives and reacting for predetermined time, a reconfigurable strong resin and a photocurable resin with repeated recyclability are obtained. The low energy consumption and cost, the high performance and economical value added of the regenerated productions, and the ease implement without changing the commodity products and manufacturing facilities make it attractive and suitable for the recycling of the resin wastes.
