自2004年推出紫外线（UV）固化聚氨酯丙烯酸酯（普阿）材料以来，我们的研究小组已将该材料广泛用于纳米图案化、仿生学、微流体和组织工程等各种应用。在这个亮点中，我们的目的是提供一个简要的概述普阿的性能和应用，特别关注的能力，调整模量（20-320 MPa）和表面能（20-60 mJ m（-2））。这些独特的功能使我们能够在各种图案化应用中使用该材料，分别作为模具和图案化薄膜。此外，可以受益于普阿的几个其它特征，例如自复制、部分固化、柔性、生物相容性和透明性。这些问题也简要描述沿着与他们的应用。
Since the introduction of ultraviolet (UV)-curable polyurethane acrylate (PUA) materials in 2004, our group has extensively used the material in various applications ranging from nanopatterning, biomimetics, microfluidics, to tissue engineering. In this highlight, we aim to provide a brief overview of the properties and applications of PUA with particular focus on the ability of tuning modulus (20-320 MPa) and surface energy (20-60 mJ m(-2)). These unique features enable us to use the material in various patterning applications as a mold and a patterned film, respectively. In addition, one can benefit from several other features of PUA such as self-replication, partial curing, flexibility, biocompatibility, and transparency. These issues are also briefly described along with their applications.
