项目摘要

We experimentally presented proof that several mechanical properties of polymer, such as elasticity, viscoelasticity, and glass transition temperature, are dependent on the size of the polymer in nano meter scale. To our knowledge, this result is the first report of the size -effect on mechanical property of nano materials. We fabricated nano spring made of 〜200 nm diameter poly (methylmethacrylate) nanowire by means of two-photon photopolymerization. We manipulated the fabricated nano spring in solution by laser trapping method, and measured the spring constant of the nano spring. We installed temperature controllable stage into our hand -made laser trapping system, which made it possible to change the temperature of the nano spring from about 200 to 400 K during spring constant measurement. First, we found that the elasticity of nano size polymer is 109 times smaller than that of the bulk of the same material. This giant elasticity is not related to degree of polymerization, or solve … More nt, but purely dependent on the size of polymer. We also observed that transition temperature of the polymer changes remarkably depending on the size of polymer. Actually, the transition temperature decreased more than 40 K when the size of the nano spring was decreased from 450 nm to 150 nm. The experimental data also suggest a novel functionality in polymer based nano devices, which is reversible temperature -switchable elasticity/viscoelasticity. The change of elasticity/viscoelasticity by transition temperature is actually intrinsic in any polymer materials, and so not surprising, though the glass transition temperature of bulk polymer is usually 〜370 K. However by designing the size of polymer structures at the nanoscale, it becomes possible to control the switching temperature, even at room temperature. We also developed new polymer materials functionalized by az o-benzene contained monomers. This polymer shows refractive index change and volume change by light irradiation. We fabricated three -dimensional photonic crystals by two-photon polymeriation, and demonstrated optical switching of photonic bandgaps. Since the refractive index and volume change is induced by photo -isomerization of azo-benzene derivative, the optical switching of photonic bandgaps is reversible. These novel mechanical and optical functions we have shown through this project are intrinsic to nano-sized polymers, and would lead to exploring future novel polymer-based nanodevices. Less
我们通过实验提出的证据表明,聚合物的几种机械性能(例如弹性,粘弹性和玻璃过渡温度)取决于纳米仪表中聚合物的大小。据我们所知,该结果是对纳米材料机械性能的大小效应的首次报告。我们通过两光子光聚合化制造了由〜200 nm直径的聚(甲基丙烯酸酯)纳米线制成的纳米弹簧。我们通过激光捕获方法操纵了溶液中制造的纳米弹簧,并测量了纳米弹簧的弹簧常数。我们将温度控制的阶段安装到了手部激光捕获系统中,这使得在弹簧恒定测量过程中可以将纳米弹簧的温度从约200 K更改为400 K。首先,我们发现纳米尺寸聚合物的弹性比大部分相同材料的弹性小109倍。这种巨大的弹性与聚合程度无关,或者求解……更多,而纯粹取决于聚合物的大小。我们还观察到聚合物的过渡温度明显取决于聚合物的大小。实际上,当纳米弹簧的大小从450 nm降低到150 nm时,过渡温度降低了40 K。实验数据还表明,基于聚合物的纳米设备的新功能是可逆温度可交流的弹性/粘弹性。在任何聚合物材料中,通过过渡温度的弹性/粘弹性的变化实际上都是固有的,因此,尽管散装聚合物的玻璃过渡温度通常为〜370K。但是,通过在纳米级上设计聚合物结构的大小,即使在室温下,也可以控制开关温度,甚至可以在室温下控制开关。我们还开发了由AZ O-苯二烯含有单体功能化的新聚合物材料。该聚合物通过光照射显示折射率变化和体积变化。我们通过两光子聚合制造了三维光子晶体,并证明了光子带盖的光学切换。由于折射率和体积变化是由偶氮偶然衍生物的照片分散化引起的,因此光子带盖的光学切换是可逆的。我们通过该项目显示的这些新型的机械和光学功能是纳米尺寸聚合物的固有性,并将导致探索未来的新型聚合物基于新型聚合物的纳米版权。较少的
