This invention relates to the field of water remediation technology, specifically to a piezoelectric catalytic component and a groundwater remediation system. The piezoelectric catalytic component includes: an upper part of a piezoelectric catalytic body with a spiral channel communicating with an inlet, and a lower part with a cavity; the cross-sectional diameter of the spiral channel gradually decreases from the inlet to the end; a column is provided in the cavity, and a piezoelectric film is spirally wound around the column; the end of the spiral channel is close to the piezoelectric film at the upper end of the column; the piezoelectric film receives water containing organic pollutants flowing in from the spiral channel and catalytically degrades the organic pollutants through piezoelectric conversion; this application combines the static pressure of the water flow, accelerates the water flow through the spiral channel, the flow velocity gradually increases from top to bottom, the hydraulic impact load is correspondingly enhanced, the mechanical force flowing through the piezoelectric film is increased, low-frequency vibration excites the piezoelectric catalytic effect, maximizes the catalytic degradation capacity of the piezoelectric material, and thus improves the catalytic degradation efficiency of the piezoelectric material.

The application discloses an antistatic agent, a pressure-sensitive adhesive and application thereof, and belongs to the technical field of protective films. The antistatic agent is prepared by copolymerization of the following monomers in parts by weight: 15-25 parts of a quaternary ammonium salt monomer, 20-30 parts of a first acrylate soft monomer, 3-8 parts of a first acrylate hard monomer and 1-5 parts of a hydroxyl-containing monomer. The antistatic agent is a quaternary ammonium salt acrylate copolymer prepared by copolymerization of the quaternary ammonium salt monomer, the acrylate soft monomer, the acrylate hard monomer and the hydroxyl-containing monomer. The copolymer has both a quaternary ammonium salt conductive group and an acrylate group. The acrylate group can deeply participate in photopolymerization, so that the quaternary ammonium salt group with a conductive function is firmly anchored on the adhesive copolymer molecular chain through a covalent bond, thereby effectively solving the migration and precipitation problems of the antistatic component and realizing long-acting antistatic performance.

The present application belongs to the technical field of functional materials, and particularly relates to a coated carbon nanotube composite material and a preparation method thereof, and a functional polymer composite material and a preparation method thereof. The coated carbon nanotube composite material provided by the present application has a core-shell-shell structure coated in turn from inside to outside, wherein the carbon nanotube constitutes an inner core providing mechanical enhancement and an electrically conductive path, a silver layer coated on the surface of the carbon nanotube serves as an intermediate layer and a first antibacterial component, a copper oxide nanoparticle layer coated on the surface of the silver layer serves as an outer shell layer and a second antibacterial component, and the copper oxide layer and the silver layer form a heterojunction. The specific structure produces a synergistic effect of silver, copper oxide and carbon nanotube, so that the composite powder has the functions of high-efficiency antibiosis, antistatic and mechanical enhancement.

This invention discloses a micro-space TCM-adaptive planning and AI self-learning control method based on holistic health care in the home environment, involving the fields of family health care and intelligent environmental control technology. The method includes the following steps: S1, Initialization and Record Building: The user inputs and stores the physical condition test reports of all family members and the distribution map of the family's micro-spaces into the system. This micro-space TCM-adaptive planning and AI self-learning control method based on holistic health care in the home environment deeply integrates TCM constitution theory with family micro-space planning. Through TCM constitution record building, it clarifies the basic constitution, chronic diseases, and allergens of family members, and marks and divides each micro-space in the home according to its location, function, lighting, and ventilation. This achieves TCM-adaptive planning of the micro-spaces. Simultaneously, it matches specific environmental parameters for each space according to different constitutions, upgrading family environmental control from physical parameter adjustment to personalized adaptation to meet the needs of human health care.
