摘要： Wood fibers possess natural unique hierarchical and mesoporous structures that enable a variety of new applications beyond their traditional use. For the first time we dramatically modulate the propagation of light through random network of wood fibers. A highly transparent and clear paper with transmittance >90% and haze 90% and haze >90% is also achieved. A thorough investigation of the relation between the mesoporous structure and the optical properties in transparent paper was conducted, including full-spectrum optical simulations. We demonstrate commercially competitive multi-touch touchscreen with clear paper as a replacement for plastic substrates, which shows excellent process compatibility and comparable device performance for commercial applications. Transparent cellulose paper with tunable optical properties is an emerging photonic material that will realize a range of much improved flexible electronics, photonics and optoelectronics.

摘要： Solar cell substrates require high optical transparency, but also prefer high optical haze to increase the light scattering and consequently the absorption in the active materials. Unfortunately there is a tradeoff between these optical properties, which is exemplified by common transparent paper substrates exhibiting a transparency of about 90% yet a low optical haze (
摘要翻译： 太阳能电池基板需要高的光学透明度，而且还优选高的光学雾度以增加光散射并因此增加活性材料的吸收。 不幸的是，在这些光学性质之间存在折衷，其通过透明度为约90％但光学雾度低（<20％）的普通透明纸基材为例。 在这项工作中，我们引进了一种新型的木纤维透明纸，显示了超高光学透明度（〜96％）和超高雾度（〜60％），从而为太阳能电池设备提供了最佳的基板设计。 与先前证明的由木质纤维素纳米纤维组成的纳米纤维相比，我们的新型透明纸在透光率和雾度方面具有更好的双重性能，而且以低得多的成本制造。 这种高性能，低成本的透明纸是潜在的革命性材料，可能会影响新一代环保印刷电子产品。
