Shape memory polymers (SMPs) are a class of smart materials that change shape when stimulated by environmental stimuli. Different from the shape memory effect at the macro level, the introduction of micro‐patterning technology into SMPs strengthens the exploration of the shape memory effect at the micro/nano level. The emergence of shape memory micro/nano patterns provides a new direction for the future development of smart polymers, and their applications in the fields of biomedicine/textile/micro‐optics/adhesives show huge potential. In this review, the authors introduce the types of shape memory micro/nano patterns, summarize the preparation methods, then explore the imminent and potential applications in various fields. In the end, their shortcomings and future development direction are also proposed.

“…However, our results indicate that this phenomenon also occurs for films treated at higher temperatures, as is shown from figures 4 and 7. Other material systems showing similar wrinkled structures include polymeric films [35][36][37] and thinfilm metal/polymer bilayers when exposed to heat treatments [38] without being mechanically constrained. During the film formation process, the polymer-gel network helps accommodating the stress generated due to the volumetric contraction by creating the wrinkled surfaces.…”

ZnO-based materials are commonly used in electronic device fabrication due to the interesting piezoelectric, pyroelectric, and optical properties of this tunable band-gap semiconductor. In this research, Al-doped ZnO structures have been fabricated through continuous-flow direct writing of sol-gel inks on glass substrates. We focus on understanding the transformations occurring in the materials synthesis from solution to crystalline structures as an essential step for their use in electronic devices. We investigate the relationships between the inks' rheological properties and direct writing parameters with respect to the printed pattern dimensions, and obtained microstructures, after annealing at 500 °C. We demonstrate how, by varying the printing conditions and composition of the ink formulations, the crystallographic-growth and materials' microstructure can be controlled. Finally, we illustrate an example of the optoelectronic functionality of the directly written AZO patterns using their photosensitivity properties upon different illumination conditions as well as their flexibility. Our work aims to establish relationships between materials processing and properties in emerging additive printing methods, which is of paramount importance towards innovation and new paradigms in advanced manufacturing.

In recent years much work has been conducted in order to create patterned and structured polymer coatings using vapor deposition techniques – not only via post-deposition treatment, but also directly during the deposition process. Two-dimensional and three-dimensional structures can be achieved via various vapor deposition strategies, for instance, using masks, exploiting surface properties that lead to spatially selective deposition, via the use of additional porogens or by employing oblique angle polymerization deposition. Here, we provide a concise review of these studies.
