Cycle pathway micro-vessel network structure and application thereof

Abstract

The invention relates to a cycle pathway microvascular network structure and an application thereof. The network structure comprises cycle pathway micro-vessels, the cycle pathway micro-vessels have a multi-array penetrating type structure or a three-dimensional penetrating type structure, the structure is in a thermotropic shape memory polymer matrix, the communication ports at the ends of the micro-vessel networks are preset outside the shape memory polymer matrix, and a work fluid flows through the whole cycle networks through the communication ports at the ends of the micro-vessel networks. The cycle pathway micro-vessel network structure is applied to the thermotropic shape memory polymer. The network structure has the advantages of high heating efficiency, uniform heating and simple technology, and solves a problem that the rigidity of the shape memory polymer rapidly reduces at a glass transition temperature. The network structure enables the shape memory polymer to be effectively heated and simultaneously guarantee that the shape memory polymer has a certain rigidity and a certain strength to oppose a certain load, so the load bearing capability of the shape memory polymer is substantially improved, and application fields of the shape memory polymer are extended.

Description

technical field [0001] The invention relates to a microvascular network structure of a circulatory passage and an application thereof. Background technique [0002] In nature, many organisms use the microtubule network structure to achieve amazing functions for humans. For example, the famous German botany professor W.Bartblott discovered the "self-cleaning effect of lotus leaves" in the 1990s. Under the microscope, it is observed that the surface of the lotus leaf is covered with ultra-micro pipelines, and these pipelines are filled with air, so that a layer of nano-scale air layer is formed on the surface of the lotus leaf, so you can always see the drops falling on the lotus leaf. The water droplets on the leaves will slide down. The results of studying the structure of the lotus leaf have given birth to a number of new industries. Then there are the complex conduits that run through the bodies of plants and animals. The "conduits" in plants and the blood vessels in a...
