Mechanically and Thermally Enhanced 3D-Printed Photocurable Polymer Nanocomposites Containing Functionalized Chitin Nanowhiskers by Stereolithography

Abstract: Additive manufacturing, or simply 3D printing (3DP), where objects are built through layer-wise material deposition, has gained significant academic and industrial attention as a result of the development of advanced and functional materials requiring rapid, customized, and flexible solutions. In the context of green manufacturing, diversifying environmentally and economically sustainable material portfolios is an essential endeavor for the success of 3DP technology that uses widely available, highly valuable,… Show more

“…As for VO/NFA, an increase in the strength of the loss modulus peak indicates that the increased number of chain segments inhibits the relaxation process within the composite. A similar effect was reported by Maalihan et al for methacrylate/acrylated chitosan NCC composites …”

“…FTIR was used to analyze the UV-curing of SLA resins and the macromolecular network chemical structure of the polymer. FTIR is reported to be an effective and widely used technique to investigate the UV-curing reaction of polymer resins. ,, All FTIR spectra from uncured resin and printed samples are shown in Figure S4. Peaks at 810, 980, 1409, and 1629 cm –1 indicate the vinyl bonds, which are characteristic of acrylic groups .…”

“…The sample of PCR-1/6/3 exhibited the highest T g value of 160 °C, which was higher than the values exhibited by most PCRs used for vat polymerization in 3D printing. 46,47 Thus, PCR-1/6/3 could increase the upper limit of temperature used for 3D printing. In addition, the motion of the molecular segments was restricted in PCR-1/6/3, leading to a narrower intensity peak in the glass-transition range of the curve.…”
