Cellulose nanocrystals are promising as a new class of reinforcing material for the preparation of nanostructured composites. We report here the preparation of cellulose nanocrystal multilayer composites with poly(diallyldimethylammonium chloride) using layer-by-layer assembly (LBL) technique. The LBL assembly was characterized with UV-Vis spectroscopy and ellipsometry. The average thickness of a single bilayer was found to be 11 nm. AFM and SEM characterization revealed uniform coverage and densely packed cellulose crystal surface.
纤维素纳米晶体作为一类新型增强材料在制备纳米结构复合材料方面很有前景。我们在此报告了使用逐层组装(LBL)技术制备聚(二烯丙基二甲基氯化铵)纤维素纳米晶体多层复合材料的过程。通过紫外可见光谱和椭偏仪对LBL组装进行了表征。发现单个双层的平均厚度为11纳米。原子力显微镜(AFM)和扫描电子显微镜(SEM)表征显示覆盖均匀且纤维素晶体表面堆积致密。
