“…Among these techniques are electrochemical machining, micro-milling, ion-beam etching, hot embossing, lithography, mechanical texturing, and LST. A combination of grafting and texturing to improve the wettability and tribological properties of polymer brushes [6] was explored with the aim of prolonging their life. Results of the process showed that the micro-textures protected the brushes from wear and increased their tribological performance, hence extending their service life.…”

Micro- and nanoscale structures produced on surfaces of metals, polymers, ceramics, and glasses have many important applications in different fields such as engineering, medical, biological, etc. Laser ablation using ultrashort pulses has become the prominent technique for generating different surface structures for various functional applications. Ultrashort laser ablation proved to be ideal for producing structures with dimensions down to the nanometre scale. In comparison to other texturing techniques employed to create micro/nano features such as electrochemical machining, micro-milling, ion-beam etching, hot embossing, lithography, and mechanical texturing, ultrashort laser ablation produces high-quality surfaces at low cost in a one-step non-contact process. Advantageous characteristics of polymers such as high strength-to-weight ratio, non-corrosive nature, and high electrical and thermal resistance, have made polymers the preferred choice compared to other materials (e.g., steel, aluminium, titanium) in several fields of application. As a result, laser ablation of polymers has been of great interest for many researchers. This paper reviews the current state-of-the art research and recent progress in laser ablation of polymers starting from laser-material interaction, polymer properties influenced by laser, laser texturing methods, and achievable surface functionalities such as adhesion, friction, self-cleaning, and hydrophilicity on commonly used polymeric materials. It also highlights the capabilities and drawbacks of various micro-texturing techniques while identifying texture geometries that can be generated with these techniques. In general, the objective of this work is to present a thorough review on laser ablation and laser surface modification of a variety of industrially used polymers. Since direct laser interference patterning is an emerging area, considerable attention is given to this technique with the aim of forming a basis for follow-up research that could pave the way for potential technological ideas and optimization towards obtaining complex high-resolution features for future novel applications.

“…Shen et al presented a method to increase the lifetime and stability of a low-friction polymer layer by grafting chains onto a laser-textured surface. 72 The use of a micro-textured substrate enable protection of polymer chains and expands application possibilities. Inspired by natural lubricants, Rong et al designed a system that mimics articular cartilage, exhibiting extremely low friction even under high contact pressures.…”

Surface‐grafted polymer brushes (PBs) are a versatile class of thin coatings that exhibit unique properties due to their densely grafted polymer chains. PBs are typically formed through surface‐initiated polymerizations, particularly reversible deactivation radical polymerizations, and macromolecules adopt extended conformations that differentiate them from classical polymer films. This review explores various applications of PBs, emphasizing their macromolecular ordering, dynamic conformational changes, anisotropic properties, and so forth. The growing interest in utilizing PBs for functional coatings is discussed in various fields, including electronic, biological, and environmental applications. In electronic applications, PBs find relevance in photovoltaics, energy storage devices, organic light‐emitting diodes, and organic electronics, showcasing their potential in advancing electronic technologies. In biological applications, they contribute to the formation of antifouling and antibacterial coatings, as well as superior lubrication and cellular adhesion, making them valuable in biomedical settings. Other applications include biosensors, bioimaging systems, and drug delivery systems, highlighting their significant contributions to medical advancements. Additionally, PBs play an important role in environmental applications such as water and wastewater treatment. A variety of recent examples of the applications of surface‐grafted PBs are presented, providing insights into their unique properties and architectures that contribute to their success in demanding areas of science and technology.

Among the methods for onsite detection of specific biomolecules, the use of retroreflective Janus particles (RJPs) is a simple and efficient method for biophotonic probes to detect biotarget molecules with spatioselectivity, which can make the RJPs align toward light sources after capturing the target biomolecules, enhancing retroreflection. Because RJP has two distinct regions with different properties, specific reagents can be easily functionalized through chemical reactions between the functional groups and biotarget molecules. The number of functional groups on RJP will be the critical parameter for efficiency of sensing ability. Here, we introduce clickable (azide) polymer brush on surface of RJP via different surface polymerization methods (grafting to and grafting from method). Azide groups allow for the easy modification of dibenzocyclooctyne‐linked biomolecules onto silica particles through click chemistry. We prepare RJPs with different quantities of azide functional groups on their surfaces via solvent volatilization method and metal deposition. Using a retroreflective immunosensing system, we perform sensitive detection of target biomolecules.This article is protected by copyright. All rights reserved
