Get brick of natural mother-of-pearl “ - structure of shape of slimy ” layer inspires reporter to learned from university of science and technology recently, development of group of Yu Shuhong academician gives this school a kind of new-style spacecraft is outer defend material —— gets together acyl inferior amine - Na Miyun's mother is compound film. This kind of new material gets brick of natural mother-of-pearl “ - the inspiration of structure of shape of slimy ” layer, used distinctive copy to give birth to a design, its are mechanical function and dimensional extreme environment are able to bear or endure suffer a gender to all get remarkable promotion, hopeful is replaced show some getting together acyl inferior amine radical is compound velar stuff. This achievement was published at a few days ago " advanced material " . Get together acyl inferior amine film because its superior mechanical performance, superexcellent thermal stability is able to bear or endure with what highlight chemical sex, and become aerospace detector “ to defend the superexcellent stuff that takes ” . However, like polymer of other carbon hydrogen, this material is atttacked extremely easily in aerospace environment by atomic oxygen, bring about physics and mechanical function to drop quickly. In addition, cosmic ray radiate and dimensional fragment are bumped wait for extreme environment to also offer an acid test to its stability. The “ brick that group of Yu Shuhong academician gets natural mother-of-pearl - structure of shape of slimy ” layer is inspired, use what early days develops to have exceedingly good and mechanical function and ultraviolet screen function and but master serves as the Na Miyun of extensive preparation build base yuan, with get together acyl inferior amine van body is assembled in all get getting together acyl inferior amine - Na Miyun's mother is compound film, this those who use mica is advantageous asking for character will make up for get together acyl inferior the inadequacy of amine. Distinction at before the monolayer structure of compound film designs rice of accept of copy pearl layer, researcher deserves to compare through changing constituent, couplet usage built spray of have the aid of and hot solidify to have double deck kind of pearl layer structure get together acyl inferior amine - Na Miyun's mother is compound film, make its carry a layer on the head to have more compact accept rice mica sheet. Strategy of this kind of design realized material not only the effective promotion of mechanical function, and make the surface on its oxygen, ultraviolet to atom radiation and dimensional fragment have taller counteractive property. Consider to make clear, quantity of model of the tensile strength that this kind of new-style copy gives birth to compound film, Yang and exterior hardness are 125 million handkerchief, 2.2 auspicious handkerchief and 0.37 auspicious handkerchief respectively, than pure get together acyl inferior amine film parts tower above 45% , 100% with 68% . As a result of distinctive double deck kind mother-of-pearl structure and micaceous accept rice piece inherent performance dominant position, double deck gets together acyl inferior amine - compound film shows Na Miyun's parent more advantageous atomic oxygen is able to bear or endure suffer a gender, apparent excel is pure get together acyl inferior amine film, monolayer kind of mother-of-pearl structure get together acyl inferior amine - micaceous and compound film gets together with what report before acyl inferior amine radical composite material. In addition, its fight ultraviolet ageing sex and high temperature stability to also get apparent promotion. The personage inside course of study thinks, the structure of mother-of-pearl of copy of distinctive double deck that this research offers devises strategy, build for the design other composite material offerred high-powered accept rice new thinking.
