3D printing bionic hydrophilic PVA hydrogel beetle back device for water collection and printing method of 3D printing bionic hydrophilic PVA hydrogel beetle back device
The invention relates to the technical field of bionics, in particular to a 3D printing bionic hydrophilic PVA hydrogel beetle back device for water collection and a printing method of the 3D printing bionic hydrophilic PVA hydrogel beetle back device. The preparation method comprises the following steps of preparing a beetle back template with a convex surface through a photocuring three-dimensional forming technology, and preparing the hydrophilic PVA hydrogel bionic beetle back by copying the surface morphology of the beetle back template. The unique arch-shaped protruding structure on the beetle back plays a role in integrating curvature in the fog water collecting and transporting process, and an effective water collecting and transporting system is given to the surface of the beetle back surface through the Laplace pressure induced by the surface gradient of a triangular structure; and by introducing the 3D printing technology, rapid manufacturing and large-scale production can be achieved, and the important effect on relieving the water shortage problem in the desert area is achieved.
本发明涉及仿生的技术领域，尤其涉及一种用于水收集的3D打印仿生亲水PVA水凝胶甲虫背装置及其打印方法。先通过光固化三维成型技术制备含有凸起表面甲虫背模板，再通过复制甲虫背模板表面形态制备亲水PVA水凝胶的仿生甲虫背。甲虫背独特的拱形凸起结构在雾水收集和运输过程中起到了集成曲率的作用，并且三角结构的表面梯度诱发的拉普拉斯压力赋予了甲虫背表面有效的水收集和传输系统。3D打印技术的引入能够快速制造和大规模生产化，对缓解沙漠地区的缺水问题产生重要的作用。
