详细研究了通过针状颗粒合成具有“纸牌屋”结构表面的微管的条件。使用氢氧化镁和二氧化碳作为起始原料，在反应过程中形成三水碳酸镁作为亚稳相。随后，在三水碳酸镁制备碱式碳酸镁的过程中，在适当控制温度和氢氧化钠添加量的条件下，通过三水碳酸镁针状颗粒得到表面具有纸牌结构的微管。通过调节针状颗粒的形成条件，可以将微管的孔径控制在0.5-6微米范围内。此外，发现微管释放萘的可持续性比萘晶体释放的可持续性高约6倍。
The conditions for synthesizing microtubes with a surface of "house of cards" structure via needlelike particles were examined in detail. Magnesium carbonate trihydrate was formed as a metastable phase in the reaction process using magnesium hydroxide and carbon dioxide as starting materials. Subsequently, in the formation of basic magnesium carbonate from magnesium carbonate trihydrate, microtubes with a surface of house of cards structure were obtained via needlelike particles of magnesium carbonate trihydrate under certain conditions where the temperature and added amount of sodium hydroxide were properly controlled. The pore size of the microtubes could be controlled within a range of 0.5-6 microm by adjusting the condition of needlelike particle formation. In addition, the sustainability of naphthalene release from the microtube was found to be about 6 times higher than that from naphthalene crystal.
