The magnetite with a mean diameter of 8nm was prepared by chemical coprecipitation methods. By the addition of nonionized oleic acid to the suspension of magnetite in solution during precipitation, the magnetite nanoparticles were coated with a double surfactant layer. A gel-like precipitated precursor is then formed because of the hydrophobic interaction among those coated units. By transferring of this precursor to an organic solvent, the surfactant double layer on Fe〓O〓 nanoparticles reduces to one; however, it still remains as a double layer by transferring to an alkaline aqueous solution. Both these cases give in stable colloids of superparamagnetic Fe〓O〓 nanoparticles.

从解决无机磁性Fe〓O〓颗粒与有机烯类单体的相容性入手，采用化学共沉淀法，制备了平均直径为8nm的超顺磁性Fe〓O〓颗粒，在制备过程中以非离子形式引入油酸，在Fe〓O〓颗粒表面形成一个具有双层结构的疏水外壳，并通过疏水相互作用凝聚成磁性Fe〓O〓凝胶，能够以单分子层结构形式溶解在非极性溶剂中，也能够以双分子层结构形式溶解在碱性水溶液中，形成稳定的超顺磁性Fe〓O〓溶胶。

Because the photospheric temperature of carbon stars are less than 3000K and the temperature of rich-dust envelope formed by the mass loss is lower, and therefore most of the energy from carbon stars are radiated between 1 to 60um range, in which the vibrational and ro-vibrational bands of many molecules also lies, the study of infrared spectra in this wavelength range is very important to reveal chemical compositions, dust formation process, the atmospheric structure and evolutionary status of stars.

碳星光球的有效温度不超过3000K，同时较大的质量损失率形成了富碳的尘埃壳层，以致于它的辐射能量主要集中在1—60μm的红外波段上，并且许多分子的转动振动能谱也集中在红外，因此在红外波段的研究对揭示碳星化学成份及其分布、尘埃形成过程、恒星大气结构和演化状态都有十分重要的意义。
