preparation example Construction

[0021] The present invention provides a preparation method for the intelligent hydrogel robot described in the above technical solution, comprising the following steps:

[0022] Mix hydroxyethyl methacrylate, acrylic acid, cross-linking agent, and photoinitiator to form a precursor solution, and then irradiate to obtain an intelligent hydrogel robot that can cruise and collect plastic pollutants on the water surface.

[0023] In the present invention, unless otherwise specified, the required preparation materials are commercially available products well known to those skilled in the art.

[0024] The invention mixes hydroxyethyl methacrylate, acrylic acid, a crosslinking agent and a photoinitiator to form a precursor solution. In the present invention, the crosslinking agent is preferably ethylene glycol dimethacrylate, and the photoinitiator is preferably 2-hydroxy-2-methylpropiophenone. In the present invention, the volume ratio of the hydroxyethyl methacrylate, acrylic aci...

Embodiment 1

[0031] Preparation of smart hydrogel precursor: mix hydroxyethyl methacrylate and acrylic acid at a volume ratio of 2:1, and then add cross-linking agent ethylene glycol dimethacrylate, the volume of which and hydroxyethyl methacrylate The ratio is 1:10; then add photoinitiator 2-hydroxy-2-methylpropiophenone, its volume ratio to hydroxyethyl methacrylate is 1:2, after the above liquid is mixed evenly, high-purity nitrogen gas is introduced into the shading After 5 minutes, the prepared precursor solution was obtained.

[0032] Mold making: Use AutoCAD software to model the mold in 3D, and save the modeling file in dwg. format; import the modeling file in dwg. format into the laser cutting machine, laser cut the acrylic sheet, and make an acrylic punch, and the protrusion is a cylinder shape, 1 cm in diameter, and 3 mm in height; on the acrylic punch, use the PDMS molding process to manufacture a PDMS mold.

Embodiment 2

[0036] According to the scheme described in Example 1, the only difference is that the volume ratio of hydroxyethyl methacrylate to acrylic acid is 1:1, and the volume ratio of the remaining liquids remains unchanged. The volume ratio of hydroxyethyl methacrylate is still 1:10; the volume ratio of photoinitiator 2-hydroxyl-2-methylpropiophenone and hydroxyethyl methacrylate is still 1:2.

[0037]According to the scheme described in Example 1, the swimming robot that moves autonomously on the water surface in Example 2 is verified. The results show that the intelligent hydrogel robot in Example 2 can also move autonomously after being released to the water surface, and it is released to the point where there is plastic pollution. The water surface of objects can also move autonomously and collect plastic pollutants.

[0038] It can be seen from the above embodiments that the intelligent hydrogel robot provided by the present invention can be used to collect plastic pollutants c...

Abstract

The invention belongs to the technical field of robots, and particularly relates to an intelligent hydrogel robot capable of cruising and collecting plastic pollutants on the water surface and a preparation method of the robot. The intelligent hydrogel robot is completely composed of novel intelligent hydrogel formed by hydroxyethyl methacrylate and acrylic acid through photo-initiation polymerization, and the intelligent hydrogel robot is released to the surface of water-containing liquid. The intelligent hydrogel can autonomously generate surface tension gradient difference on the water surface, so that long-time autonomous cruising on the water surface is realized under the condition of no external energy supply. In addition, the swimming robot can collect plastic pollutants on the water surface through hydrophilic and hydrophobic interaction.

Description

technical field [0001] The invention belongs to the technical field of robots, and in particular relates to an intelligent hydrogel robot capable of cruising and collecting plastic pollutants on water surfaces and a preparation method thereof. Background technique [0002] There are often plastic pollutants floating on the water surface on the river, causing water quality to deteriorate and polluting the water resource environment. However, most of the traditional processing methods are manual salvage, which is inefficient, expensive to salvage, and also poses certain dangers to salvage personnel. [0003] Hydrogel is a gel with a three-dimensional network structure that can absorb a large amount of water and swell in water. Due to its outstanding stimuli responsiveness and deformability, hydrogel can be used as an actuator and is one of the common materials for constructing soft robots. In view of this, the present invention provides a new type of intelligent hydrogel rob...
