This invention discloses a rapid self-assembly of Ti3C2T based on pH regulation. x The method for preparing MXene thin films is as follows: 1. Preparation of Ti3C2T x MXene dispersion; 2. Adjust pH to 1.5-3.0 with inorganic acid; 3. After stirring and settling, vacuum filter and self-assemble into a film; 4. After drying, peel off to obtain Ti3C2T. x MXene thin films. This invention introduces trace amounts of inorganic acid to regulate the surface charge and colloidal stability of MXene sheets, effectively weakening the electrostatic repulsion between sheets, significantly improving the film formation efficiency of vacuum filtration, and ensuring the quality of Ti3C2T films. x MXene films offer excellent conductivity and are simple and inexpensive to process, requiring no special equipment, making them ideal for achieving high-quality Ti3C2T. x The efficient and large-scale preparation of MXene thin films provides a reliable approach suitable for electromagnetic shielding, flexible electronics, and electrochemical energy storage.

The invention discloses a drain board adopting a regenerated plastic composite core board and a preparation method of the drain board, and belongs to the technical field of drain boards. The drainage plate comprises a regenerated plastic composite core plate, a filter membrane, a reinforcing sleeve and a splicing structure. The core plate takes regenerated polypropylene as a base material, glass fiber powder and a compatilizer are added to enhance the performance, and a trapezoidal drainage channel is arranged to improve the compression resistance and drainage stability. The filter membrane is made of regenerated polyester non-woven fabric and is mechanically meshed with the core plate through a needling composite process. According to the invention, high-value utilization of waste plastic is realized, the production cost is remarkably reduced, excellent mechanical properties and drainage stability are ensured, and the composite material is suitable for projects such as roadbeds, gardens, building foundation pits and the like.

The present application relates to the technical field of nanofiber membrane, in particular to an interface enhanced unidirectional liquid guiding nanofiber membrane and a preparation method thereof, the interface enhanced unidirectional liquid guiding nanofiber membrane is a gradually transition composite structure, comprising a hydrophilic response functional layer, an interface enhanced transition layer and a hydrophobic barrier layer which are sequentially compounded; the interface enhanced transition layer is a hydrophilic-hydrophobic gradually transition layer, the composition of which gradually changes from the composition of the hydrophilic response functional layer to the composition of the hydrophobic barrier layer at a mass ratio of 5:1 to 1:1. The gradually transition layer is formed by time sequence flow regulation, dynamic hydrophilic adaptation is realized, and finally a composite membrane with high interface stability, high efficient unidirectional liquid guiding and precise dynamic response is obtained, which meets the actual application requirements in many fields.
