Create an academic flowchart. Start with "Poplar Specimens" on the left, with arrows pointing to three parallel impregnation process boxes: S1(5%BX+20%ATMP), S2(5%BX+25%ATMP), S3(5%BX+30%ATMP). Arrows converge into a "Performance Evaluation" module containing icons for tests: LOI, Cone Calorimeter, TG, FTIR, XPS, SEM. A prominent arrow leads from this module to a highlighted box: "S2 (Optimal Sample)". Subsequent arrows lead to three parallel coating treatments: Tung Oil (S4), PDMS (S5), Silicone Grease (S6). Final arrows converge into a right-side "Assessment" module showing water absorption curves and ASE data, concluding with "Tung Oil/Silicone Grease for best long-term performance". The layout flows left-to-right, using color blocks to distinguish stages: Treatment, Screening, Coating, Verification.
