研究目的
To develop a urethane-methacrylate siloxane hybrid material (UMSH) that combines ceramic-like high strength, polymer-like low modulus, and high strain at fracture for use as a transparent flexible cover window for foldable displays.
研究成果
The UMSH material demonstrates a novel combination of ceramic-like high strength, polymer-like low modulus, and high strain at fracture, making it suitable for flexible cover windows in foldable displays. The molecule-level hybridization of urethane linkage and methacrylate-siloxane co-networks overcomes the mutual exclusivity of high strength and strain, offering a promising solution for flexible electronics.
研究不足
The study focuses on the synthesis and characterization of UMSH for flexible cover windows but does not explore long-term durability under environmental stressors or scalability of the synthesis process for industrial applications.
1：Experimental Design and Method Selection:
The study involved the synthesis of a urethane-methacrylate siloxane hybrid material (UMSH) through free-radical polymerization of a mixture of ladder-like structured methacrylate oligo-siloxane (LMO) resin and butylene urethane dimethacrylate (BUDM) monomer. The methodology included UV-initiated free-radical polymerization to achieve molecule-level hybridization.
2：Sample Selection and Data Sources:
Samples included LMSH (fabricated by only LMO), UMSH50, UMSH100 (fabricated by LMO/BUDM in ratios of 2:1 and 1:1, respectively), and BUMP (fabricated by only BUDM).
3：List of Experimental Equipment and Materials:
Instruments used included FT-IR for synthesis confirmation, LC-MS for yield analysis, DSC for identifying melting points, SEM for surface analysis, SAXS for micro-phase separation evaluation, nano-indentation for elastic recovery, and micro-beam bending tests for flexural properties.
4：Experimental Procedures and Operational Workflow:
The process involved synthesizing BUDM, mixing with LMO, UV polymerization, and characterization of optical and mechanical properties.
5：Data Analysis Methods:
Data analysis included calculating methacrylate conversion from FT-IR spectra, evaluating mechanical properties from stress-strain curves, and assessing toughness from fracture tests.
