As an environmentally friendly aerogel with outstanding performances, the improvement of mechanical properties is urgently required for cellulose aerogel development. In this study, a cellulose aerogel with good mechanical properties was successfully fabricated using nanocrystalline cellulose (NCC) as reinforcer. Characterization results demonstrated that NCC was embedded well into the cellulose aerogel. Tests and evaluation showed that the compressive modulus of the NCC reinforced cellulose aerogel was significantly improved, about 6 times higher than that of the pure cellulose aerogel. Furthermore, after modification with trimethylchlorosilane via a cold plasma treatment, the NCC reinforced aerogel became hydrophobic but its oleophilic property remained. This aerogel showed good adsorption capacity, reached saturation rapidly and possessed good reusability. Reinforced mechanical properties with NCC make this cellulose aerogel a very promising material for highly efficient separation and extraction of organic pollutants and oils from water.

用纳米晶纤维素作为增强剂对纤维素气凝胶进行机械增强
作为具有优异性能的环保气凝胶，迫切需要改善纤维素气凝胶的机械性能。在这项研究中，使用纳米晶体纤维素（NCC）作为增强剂成功地制造了具有良好机械性能的纤维素气凝胶。表征结果表明，NCC很好地嵌入了纤维素气凝胶中。测试和评估表明，NCC增强纤维素气凝胶的压缩模量得到了显着改善，比纯纤维素气凝胶的压缩模量高出约6倍。此外，修改与三甲基氯硅烷后经由经过冷等离子体处理后，NCC增强气凝胶变为疏水性，但其亲油性得以保持。该气凝胶显示出良好的吸附能力，迅速达到饱和并且具有良好的可重复使用性。NCC增强的机械性能使这种纤维素气凝胶成为一种非常有前途的材料，可以高效地从水中分离和提取有机污染物和油类。
