3D polycatenated architected 3D聚鏈化建筑材料 ▲ 作者：WENJIE ZHOU, SUJEEKA NADARAJAH, LIUCHI LI, ANNA GUELL IZARD, HUJIE YAN, AASHUTOSH K. PRACHET, PAYAL PATEL, XIAOXING XIA, AND CHIARA DARAIO ▲鏈接： https://www.science.org/doi/10.1126/science.adr9713 ▲摘要： 建筑材料的特性來源于其內(nèi)部結(jié)構(gòu)元素的幾何排列。他們的設(shè)計依靠連續(xù)的成員網(wǎng)絡(luò)來控制整體的力學(xué)行為。研究者介紹了一類由離散的連接環(huán)或籠狀顆粒聯(lián)鎖在三維網(wǎng)絡(luò)中組成的材料，形成多聯(lián)結(jié)構(gòu)材料（PAM）。他們提出了一個通用的設(shè)計框架，將任意晶體網(wǎng)絡(luò)轉(zhuǎn)化為粒子連接和幾何形狀。 在響應(yīng)小的外部載荷時，PAM表現(xiàn)得像非牛頓流體，表現(xiàn)出剪切變薄和剪切增厚的響應(yīng)，這可以通過它們的陽離子拓?fù)浣Y(jié)構(gòu)來控制。在較大的應(yīng)變下，PAM表現(xiàn)為晶格和泡沫，具有非線性應(yīng)力—應(yīng)變關(guān)系。在微觀尺度上，研究證明了PAM可以改變其形狀以響應(yīng)施加的靜電荷。PAM的獨(dú)特特性為開發(fā)刺激響應(yīng)材料、能量吸收系統(tǒng)和變形結(jié)構(gòu)鋪平了道路。 ▲ Abstract： Architected materials derive their properties from the geometric arrangement of their internal structural elements. Their designs rely on continuous networks of members to control the global mechanical behavior of the bulk. In this study, we introduce a class of materials that consist of discrete concatenated rings or cage particles interlocked in three-dimensional networks, forming polycatenated architected materials (PAMs). We propose a general design framework that translates arbitrary crystalline networks into particle concatenations and geometries. In response to small external loads, PAMs behave like non-Newtonian fluids, showing both shear-thinning and shear-thickening responses, which can be controlled by their catenation topologies. At larger strains, PAMs behave like lattices and foams, with a nonlinear stress-strain relation. At microscale, we demonstrate that PAMs can change their shapes in response to applied electrostatic charges. The distinctive properties of PAMs pave the path for developing stimuli-responsive materials, energy-absorbing systems, and morphing architectures. |
