Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
In this work, novel acrylate-based photosensitive resins designed for vat photopolymerization (VPP) are prepared to fabricate 3D-printed monolithic structure for water technology. The formulation consisting of poly (ethylene glycol) diacrylate (PEGDA), plant-based resin was prepared with addition of 2 different comonomers, 1,4-butanediol diacrylate (BDDA) and 1,6-hexanediol diacrylate (HDDA). The influence of comonomer concentration on the thermomechanical properties is systematically investigated. 3D-printed monolithic structure was further grafted with silane coupling agent to enhance the moisture absorption and hydrophobicity to be applied for water environment. The result showed that PEGDA with 3wt.% of HDDA has greatest Young’s modulus (595.77MPa), tensile strength (3.08 MPa), and elongation at break (11.2%), whereas PEGDA with 3wt. % of BDDA has the highest storage modulus (306 MPa). Surface grafting with single silane agent on the 3D-printed monolithic structure was identified to have a more balance effect than hybrid silane coupling agent for the lowering of moisture absorption and increase the hydrophobicity behavior without causing any cracking in the inner truss. The 3D-printed monolith functionalized with silane grafted GLYMO achieved a Young’s modulus and tensile strength of 601.78MPa and 9.34 x 106 MPa respectively. The synergistic effect of 3D-printed monolith with silane coupling agent was identified to have stable chemical and mechanical for practical application in water.
