摘要：

TG/DTG analysis revealed that the volatility of thermally stable volatile corrosion inhibitors (VCIs) may be enhanced by their absorption on porous inorganic substrates, such as zeolites and diatomaceous earths (DE). Host-guest systems of dicyclohexylammonium p-nitrobenzoate and phosphate were studied as possible substitutes for dicyclohexylammonium nitrite in the production of interactive dispersion-type LDPE/EVA films with anticorrosive properties. Corrosion testing results showed that all VCIs had their efficiency increased by zeolites, and that the phosphate greatly benefited from the use of DE. (C) 2001 Elsevier Science Ltd.
