“…Guan et al. used oxovanadium(IV) 8‐hydroxyquinoline (8‐Q) complex and oxovanadium(IV) acetylacetonate (acac) complexes anchored on to amino‐modified SBA‐15 as catalyst for epoxidation of styrene using oxygen as oxidant(Scheme 39) . Styrene epoxidation was carried out in the presence of catalyst in acetonitile solvent at 80 °C while introducing air at a flow rate of ∼80 ml min.…”

Epoxidation of styrene under heterogeneous catalyzed conditions provides environmentally friendly routes to produce styrene oxide, an important synthetic intermediate for synthesis of perfumes, epoxy resins, plasticizers, drugs, sweeteners and fine chemicals. The present review explores epoxidation of styrene under heterogeneous catalysed conditions using a variety of catalysts such as metal nanoparticles, metal oxides (of group 12 and 13 metals, transition metals, rare earth metals), transition metals and complexes, polyoxometallates, microporous and mesoporous materials (zeolites, modified zeolites, organic/inorganic porous hybrid materials, porous metal oxides, SBA 15) and polymers using hydrogen peroxide (H2O2), tert‐butyl hydroperoxide (TBHP), air or oxygen as oxidants.The use of salen based transition metal complexes and of chiral porphyrins as catalysts in asymmetric epoxidation of styrene is also reviewed. The reaction mechanism studies of most of these reactions suggest an intermediate formation of a reactive metal‐oxygen species, by interactions between the catalyst and oxidant.

“…Wang et al [ 10 ] enhanced the laser welding strength of polymethyl methacrylate (PMMA) and polybutylene terephthalate (PBT) by using PC film as the intermediate layer. In 2017, Liu et al [ 11 ] enhanced the laser transmission welding strength of polyvinyl chloride (PVC) and polyamide 66 (PA66) sputtered aluminum thin film through magnetron sputtering. Grafting modification, coating, and adding intermediate layer can enhance the laser transmission welding performance of dissimilar polymers.…”

Due to their large compatibility difference, polyethylene (PE) and polyoxymethylene (POM) cannot be welded together by laser transmission welding. In this study, PE and POM are pretreated using plasma that significantly enhances their laser transmission welding strength. To understand the mechanism underlying the laser welding strength enhancement, surface modification is analyzed using contact angle measurements, atomic force microscopy (AFM), optical microscopy, and X-ray photoelectron spectroscopy (XPS). Characterization results show that the plasma surface treatment improves the surface free energy, significantly enhancing the wettability of the materials. The increase in surface roughness and the generation of homogeneous bubbles contribute to the formation of mechanical micro-interlocking. The oxygen-containing groups introduced by the oxygen plasma treatment improve the compatibility of PE and POM, and facilitate the diffusion and entanglement of molecular chains and the formation of van der Waals force.

“…[ 207 ] For several assembly incompatible polymers, pre‐welding surface treatment needs to be performed, such as plasma activation, sputtering of metal film, and the introduction of additives, compatible interlayer or grafted polymer films with reactive adhesive agent systems. [ 208,209 ] Moreover, ultrasonic microwelding, which combines the advantages of inserted metal parts, local heating and high efficiency, has improved the homogeneity and emerged as a promising technique. [ 206,210,211 ] Nevertheless, explorations of new process friendly laser systems, materials compositions, and additives are among the areas of current and future trends in LTW research.…”

Current and Future Trends for Polymer Micro/Nanoprocessing in Industrial Applications

et al. 2022

View full text Add to dashboard Cite

Polymers are widely used in optical devices, electronic devices, energy‐harvesting/storage devices, and sensors, owing to their low weight, excellent flexibility, and simple fabrication process. With advancements in micro/nanoprocessing techniques and more demanding application requirements, it is becoming necessary to realize high‐resolution fabrication of polymers to prepare miniaturized devices. This is particularly because conventional processing technologies suffer from high thermal stress and strong adhesion/friction, which can irreversibly damage the micro/nanostructures of miniaturized devices. In addition, although the use of advanced fabrication methods to prepare high‐resolution micro/nanostructures is explored, these methods are limited to laboratory research or small‐batch production. This review focuses on the micro/nanoprocessing of polymeric materials and devices with high spatial precision and replication accuracy for industrial applications. Specifically, the current state‐of‐the‐art techniques and future trends for micro/nanomolding, high‐energy beam processing, and micro/nanomachining are discussed. Moreover, an overview of the fabrication and applications of various polymer‐based elements and devices such as microlenses, biosensors, and transistors is provided. These techniques are expected to be widely applied for multiscale and multimaterial processing as well as for multifunction integration in next‐generation integrated devices, such as photoelectric, smart, and biodegradable devices.
