“…Among various 3D printing techniques, photopolymerization has attracted attention for its unique advantages such as high production rate, mild reaction temperature, low level of volatile organic compounds (VOCs), low energy consumption, excellent spatial and temporal control, etc. It is widely applied in the domains of dental materials, [24] coatings, [25] and adhesives [26] . The photopolymerization process can be carried out using a variety of light sources, including lasers, DLP (digital light processing) projectors, or LCD (liquid crystal display) screens [27] .…”

The fabrication of structured zeolite adsorbents through photopolymerization‐based 3D printing which offers a solution to the limitations of conventional shaping techniques has been demonstrated but many parameters still need to be optimized. In this study, we studied the influence of zeolite compensation cations on the photopolymerization and the composite’s properties. Modified zeolites (LTA 4A and FAU 13X exchanged with K+, Li+, Sr2+, Ca2+ or Mg2+) were incorporated in PEGDA with BDMK as photoinitiator, and the formulation was cured under mild conditions (LED@405 nm, room temperature, under air). Our results indicate that the nature of zeolite compensation cations affects the colorimetric properties of polymer/zeolite composites: a better translucency parameter results in higher depth of cure. After calcination at 650 °C and complete removal of PEGDA, pure zeolitic monoliths were tested for adsorption of gas molecules of interest (carbon dioxide, dichlorobenzene and water). Structured 4A and 13X monoliths obtained by 3D printing exhibit comparable adsorption capacity to commercial beads prepared from the same zeolites. This study enhances our understanding of the photopolymerization process involved in the production of polymer/zeolite composites. These composites are used in the fabrication of zeolitic objects through 3D printing, offering potential solutions to various environmental and dental challenges.

“…Recently, chemical modification methods have been adopted in industrial fields to improve the adhesion of PEEK. Zhang et al proposed a method to introduce epoxy groups of a polymer brush by generating free radicals in PEEK under ultraviolet irradiation [23]. Furthermore, Miyagaki et al introduced epoxy groups to a PEEK surface using a chemical reaction system based on the Friedel-Crafts reaction and reported improved bond strength with epoxy resin adhesives [24].…”

Recently, polyetheretherketone (PEEK) has shown promising dental applications. Surface treatment is essential for dental applications owing to its poor surface energy and wettability; however, no consensus on an effective treatment method has been achieved. In this study, we attempted to carboxylate PEEK sample surfaces via Friedel–Crafts acylation using succinic anhydride and AlBr3. The possibility of further chemical modifications using carboxyl groups was examined. The samples were subjected to dehydration–condensation reactions with 1H,1H-pentadecafluorooctylamine and N,N’-dicyclohexylcarbodiimide. Furthermore, the sample’s surface properties at each reaction stage were evaluated. An absorption band in the 3300–3500 cm−1 wavenumber region was observed. Additionally, peak suggestive of COOH was observed in the sample spectra. Secondary modification diminished the absorption band in 3300–3500 cm−1 and a clear F1s signal was observed. Thus, Friedel–Crafts acylation with succinic anhydride produced carboxyl groups on the PEEK sample surfaces. Further chemical modification of the carboxyl groups by dehydration-condensation reactions is also possible. Thus, a series of reactions can be employed to impart desired chemical structures to PEEK surfaces.

“…[17] In parallel, the surface modification for adhesion improvement by GMA polymerization has been also developed by combining plasma activation and photopolymerization with ultraviolet radiation, to increase the adhesion strength on the interface. [18,19] On the other hand, the syntheses of several GMA copolymers have been studied as adhesives too. In this way, it has been reported the achieving of GMA and butyl acrylate (BA) copolymers by emulsion, and their behaviour as adhesion additives.…”

The adhesion properties of poly(glycidyl methacrylate (GMA)‐co‐butyl acrylate (BA)) statistical copolymers, synthesized by atom transfer radical polymerization (ATRP), are investigated employing three different curing agents or hardeners, such as diethanolamine (DEA), dicyandiamide (DICY), and 2‐cyanoacetamide (2‐CA) on copper, iron, brass, aluminum, and titanium metal surfaces. This work describes the treatment of the different surfaces, establishes the optimal curing conditions from differential scanning calorimetry (DSC) analysis of these novel adhesive systems, and evaluates the results of the single‐lap shear test for metal joints. Thus, by dynamic DSC measurements of the mixtures, a low curing temperature of 90 °C is defined when DEA is used as a curative; while systems based on DICY and 2‐CA require temperatures of 150 °C and 160 °C, respectively. In addition, the curing process of this controlled acrylic copolymer with DICY exhibits a singular behavior, possibly due to the curing reaction mechanism, where multiple epoxy‐amine ring‐opening polyaddition reactions take place between DICY's active hydrogens and epoxy groups of poly(GMA‐co‐BA). This latter curing system shows the highest adhesion features with lap‐shear strength at room temperature of 15.5 MPa, using copper as metallic substrate; however, the best results are obtained using 2‐CA as curing agent with aluminum and iron.
