Photoactive Functional Soft Materials (Preparation, Properties, and Applications) || Soft Photoactuators in Microfluidics
摘要： Microfluidics, also known as lab‐on‐a‐chip (LOC) and micro‐total‐analysis‐system (μTAS), cover a set of multidisciplinary technologies dealing with the manipulation of small amounts of liquids to perform reactions, analyses, or fundamental investigations in biology, physics, and at the interdisciplinary frontiers. In contrast to the conventional bulky bench‐top instruments and the associated manual methods to handle large amounts of biological and chemical reagents that are pretty time consuming and not so environmentally friendly, a fine control over the motion of continuous fluids or nano/picoliter‐sized discrete droplets in microscale channels is beneficial in miniaturized systems. Therefore, there is a growing interest in downscaling the corresponding processes within LOCs and still retaining cost‐effectiveness and ease of fabrication. The microfluidic systems possess intrinsic features including minimized consumption of reagents, portability, increased automation, reduced time, and cost efficiency, which make them particularly attractive from a wide range of laboratory and industrial perspectives.

Photoactive Functional Soft Materials (Preparation, Properties, and Applications) || Photomechanical Soft Nanocomposites: Synergies Between Soft Matrix and Energy Conversion Additives
摘要： Photomechanical materials can directly transform light energy into mechanical movements that provide mechanical devices with many advantages, such as non‐contact, remote control, and spatiotemporal resolution. In the past decades, a variety of photoresponsive materials have been developed, and the system based on liquid crystalline polymers (LCPs) is one of the most fascinating ones from the viewpoint of applications as soft photoactuators. However, a simple‐component material system sometimes develops into a bottleneck, such as difficulty in the realization of multiwavelength responsiveness or the flexibility of fabrication. Recently, nanocomposite materials, which combine the superiority of both organic and inorganic materials, have shown more and more potential in photomechanical researches. It is necessary to summarize the recent progresses made with reference to photomechanical soft nanocomposites. In this chapter, we will mainly discuss their design strategy, fabrication, operating principle, and potential applications.
