PMMA无机纳米复合材料的制备及性能研究的中期报告
摘要
本报告介绍了关于PMMA无机纳米复合材料制备及性能研究的中期进展。利用非水相反应法成功制备出了PMMA/AlO(OH)无机纳米复合材料，通过SEM、TEM、XRD对复合材料进行了表征。结果表明，复合材料中AlO(OH)平均粒径为25nm左右，PMMA与AlO(OH)之间具有较好的相容性，且PMMA能够包覆AlO(OH)表面。在力学性能测定方面，PMMA/AlO(OH)复合材料的凝胶时间、硬化时间、抗压强度和抗弯强度都能够显著提高，特别是在AlO(OH)质量分数为6%时，抗压强度和抗弯强度分别提高了24.3%和29.5%。本研究结果表明，PMMA/AlO(OH)复合材料具有优异的力学性能，可望在建筑、汽车、电子等多个领域得到广泛应用。
