A simple and cost-effective route was used successfully for large-scale synthesis of highly hydrophobic and oleophilic chitin sponge through a freeze-dried method followed by thermal chemical vapor deposition of methyltrichlorosilane at different relative humidity.The hydrophobic chitin sponges displayed an average pore size of 20 to 50 μm, high porosity greater than 98%, excellent elasticity and high mechanical durability.The sponges could collect a wide range of organic solvents and oils no matter on the surface or bottom of the water with absorption capacities up to 58 times of their own weight, depending on the density of the liquids.The materials could be reused after washing, recycled (with a recyclability of more than 10 times), or incinerated with the absorbed oil, showing promoting potential in environmental and sustainable applications

摘要 《数学课程标准》强调：“义务教育阶段的数学课程最终目的是为学生的终身可持续发展奠定良好的基础。”课堂教学不能有“杀鸡取卵”的功利思想，不能只关注学生在某一时间段所习得知识量的多少，而应该放眼未来，从学生终身发展的角度，让每一个学生都能获得可持续发展。 关键词 终身学习 可持续发展 自主意识 近年来，随着人们对“自然”“和谐”的追求，随着人们对“可持续”认识的深入，随着联合国教科文组
