Celite with enormous pore space inside can hold small molecules and can be well blended with polyethylene (PE) to make a Celite-PE film. Two types of Celite-PE film were prepared, one with Celite surface-treated with surfactant to reduce the hydrophilicity and another with plain Celite. The anti-rust chemical such as dicyclohexylamine, dicyclohexylamine nitrite, or diisopropylamine was allowed to permeate into celite pore in the film, and slowly evaporated to protect the packaged steel material from the rust for a long period of time. The chemical concentration in the different packaging film bags was analyzed by a gas chromatography for a month, and the anti-rust effect on iron labware was compared for a six month period. The Celite film was superior to PE film in anti-rust effect and the long-term anti-rust chemical evaporation.
