摘　　要：纳米SiO2无毒,无味,无污染,具有优异的纳米特性,与高分子聚合物具有良好的相容性,被广泛应用于改善可生物降解材料性能等领域。综述了纳米SiO2的分散稳定性能,以及纳米SiO2改性聚乳酸、聚乙烯醇等合成型生物降解材料与淀粉、纤维素、壳聚糖、蛋白质、木质素等天然高分子材料的研究进展,并从降低价格及增强性能方面,对其改性可生物降解材料替代某些通用塑料的应用前景进行了展望。The non poisonous, tasteless and non-polluting nano-SiO2 has excellent nanometer characterization and good compatibility with polymers, which are widely used to improve the material properties of biodegradable. The disper- sion-steady theory of nano-SiO2, advance of synthetic bio-degradable materials （polylactic acid, polyvinyl alcohol, etc.） and natural polymer materials （starch, cellulose, chitosan, proteins and lignin） modified by nano-SiO2 are reviewed, and the prospect of biodegradable composites substituting for some traditional plastics in the aspects of lowering prices and improving properties is proposed.
