“…[72,90] In Figure 4A, stress-strain curves show how tuning the monomer/oligomer stoichiometry in the PETMP-AGE/PEGDA coatings alters the mechanical properties of the 3D-printed models. [64] This observation aligns with previous studies, emphasizing the impact of PEGDA's molecular weight and the PETMP to PEGDA ratio on compressive performance in porous polymer fabrication via thiol-ene click chemistry. [91] Notably, increasing the thiol-allyl ether content from 30% to 50% in coatings for flexible and elastic materials enhances elongation at break while exhibiting a decrease in Young's Modulus.…”

“…[62,63] Recently, two main approaches were reported to provide a suitable resin formulation for the PAM of soft materials, including synthesizing elastomeric resins and using different polymerization mechanisms. [64][65][66][67][68][69] Bhattacharjee et al 3D-printed a commercially available PDMS-methacrylate oligomer via SLA 3D printing for microfluidic devices. [70] The mechanical properties of the 3D-printed PDMS are similar to those of conventional thermally cured PDMS.…”

An ideal vascular phantom should be anatomically accurate, have mechanical properties as close as possible to the tissue, and be sufficiently transparent for ease of visualization. However, materials that enable the convergence of these characteristics have remained elusive. We report the fabrication of patient‐specific vascular phantoms with high anatomical fidelity and optical transparency, and mechanical properties close to those of vascular tissue. These final properties were achieved by 3D‐printing patient‐specific vascular models with commercial elastomeric acrylic‐based resins before coating with thiol‐based photopolymerizable resins. Ternary thiol‐ene‐acrylate chemistry was found optimal. A PETMP/allyl glycerol ether (AGE)/polyethylene glycol diacrylate (PEGDA) coating with a 30/70% AGE/PEGDA ratio applied on a flexible resin yielded elastic modulus, UTS and elongation of 3.41 MPa, 1.76 MPa and 63.2%, respectively, in range with the human aortic wall. The PETMP/AGE/PEGDA coating doubled the optical transmission from 40% to 80%, approaching the 88% of the benchmark silicone‐based elastomer. Higher transparency correlates with a decrease in surface roughness from 2000 to 90 nm after coating. Coated 3D‐printed anatomical replicas are showcased for pre‐procedural planning and medical training with good radio‐opacity and echogenicity. Thiol‐click chemistry coatings, as a surface treatment for elastomeric stereolithographic 3D‐printed objects, address inherent limitations of photopolymer‐based additive manufacturing.This article is protected by copyright.

“…In this decade, GTMAC has been used to modify various polymeric materials. Cellulose is reacted with GTMAC [13], chitosan is connected with GTMAC [14], p-aramid fibers are attached to GTMAC [15], and poly(ethylene glycol)-diacrylate (PEGDA), trimethylolpropane-tri-acrylate (TMPTA), and trimethylolpropane tris(3mercaptopropionate) (TMPTMP) crosslinked with GTMAC [16]. Among these polymeric materials, chitosan is the most promising and abundant material due to its biodegradability, biocompatibility, and nontoxicity [17].…”

Glycidyl-trimethylammonium chloride (GTMAC) containing quaternary ammonium (QA) groups is commonly used as a base catalyst for any organic reaction. This research prepared a novel composite of GTMAC attached to chitosan-coated magnetic material (MM/Chi/GTMAC) using a precipitation method. The effect of chitosan and GTMAC contents on MM/chi/GTMAC properties was studied, where the chitosan content varied from 0, 0.3, 0.5, 1.0, and 3.0 mol, and GTMAC varied from 0, 0.3, 0.8, 1.0, 1.5, and 3 mL with the constant mass of MM (0.4640 g). The physicochemical and morphological properties were characterized with FTIR, SEM-EDX, XRD, TGA, UV-vis, AAS, and zeta-sizer, and the magnetic strength was simply tested with an external magnet. The result showed that a mixture containing chitosan and GTMAC of 0.358 g and 1.5 mL was an optimum composition, in which MM/chi(0.5)/GTMAC(1.5) has high thermal stability, low chitosan and Fe solubility, and optimum content of QA (0.284 mol/g) without loss of magnetic strength. The higher the amount of chitosan, the lower the magnetic properties, and the higher the GTMAC did not increase the QA content. Therefore, the composite produced has the potential to be a novel heterogeneous base catalyst that is quickly recovered from any organic reaction media.
