Collaborative Research: Rational Design Of Polymeric Microtruss Structures As Highly-Ordered Multifunctional Coatings

合作研究：高分子微桁架结构作为高度有序多功能涂层的合理设计。麻省理工学院材料科学与工程系，爱荷华州州立大学，艾姆斯，麻省理工学院材料科学与工程系，剑桥，马萨诸塞州本项目的目标是研究简单的桥状（技术术语是桁架）形状的塑料结构。到目前为止，还没有人把这些东西做得很小。这些结构将是如此之小，一个不能看到个别部分的桁架与你的眼睛。为了制造这样的小东西，人们需要使用一种特殊的塑料，称为光刻胶。通过简单地将光照射在光致抗蚀剂上，可以制作形状。这些微小的塑料桁架是开放的，它们之间有很大的空间，就像人们看到的手机塔和桥梁的横梁一样。因此，这种结构的整体重量相当低。这些新型的微型轻质桁架将非常坚固，可用于制造无人机（UAV）等设备，也可用于制造士兵穿的防弹衣。去做研究。学生必须学习材料设计和工程方面的前沿基础研究。从事这个项目的教授将继续努力，通过与几个招聘项目合作，帮助代表性不足的高中生暑期实习，来格鲁吉亚理工学院和麻省理工学院与研究生一起工作，以增加攻读科学和工程高级学位的学生人数。

COLLABORATIVE RESEARCH: RATIONAL DESIGN OF POLYMERIC MICROTRUSS STRUCTURES AS HIGHLY-ORDERED MULTIFUNCTIONAL COATINGSVladimir V. Tsukruk, Edwin L. ThomasMaterials Science and Engineering Department, Iowa State University, Ames IAMaterials Science and Engineering Department, MIT, Cambridge, MAThe goal of this project is to study plastic structures that are in the shape of simple bridge-like (technical term is a truss) shapes. So far no one has made these things at really tiny sizes. These structures would be so small one cant see the individual parts of the truss with your eyes. In order to make such small things one needs to use a special type of plastic, called a photoresist. By simply shining light on the photoresist it is possible to make the shapes. These tiny plastic trusses are open and have a lot of space between their parts, just like the beams one sees that are the parts of cell phone towers and bridges. Hence the overall weight of the structure is quite low.These new kinds of tiny light weight trusses will be very strong and can be used to make devices such as unmanned air vehicles (UAVs) and also to make body armor for soldiers to wear. To do the research Ph.D. students have to learn cutting-edge fundamental research in materials design and engineering. The professors working on this project will continue their efforts to increase the number of students pursuing advanced degrees in science and engineering by working with several recruiting programs that help underrepresented high school students for summer internships to come to Georgia Tech and MIT to work alongside the graduate students to make and test the materials.
