In this study, we analyzed the temperature-dependent behavior the monolayers of the major lung surfactant phospholipid component, DPPC, at air-water interfaces under lateral compression and expansion using dissipative particle dynamics simulations and complementary experiments. Simulating air-water interface is not standard in DPD and therefore we utilized our DPD gas model developed in a previous work. The gas phase is represented through computationally efficient fictitious beads that capture essential physical characteristics of the air-water interface through carefully parameterized exponential repulsive potentials, enabling accurate simulation of interfacial phenomena. A new specifically parametrized DPD model for DPPC molecules that reproduces interfacial properties was developed. To simulate monolayers at different temperatures, we introduced a temperature scaling approach based on matching surface tension of water, with parameters that are transferable across different temperatures. The effectiveness of our approach was demonstrated by accurately reproducing that surface tension of water at different temperatures.
