STRUCTURAL ANALYSIS OF POLYISOBUTYLENE-DERIVED IONIC LIQUID-BASED DISPERSANT IN OIL FOR CARBON STABILIZATION
Abstract: Technological advancements in engine oil dispersion aim to curb carbon particle aggregation, crucial for cutting soot emissions from vehicles. This study delves into how polymeric dispersants influence carbon stabilization, highlighting optimal levels to curb excess soot formation. Misuse of dispersants can destabilize carbon in oil, exacerbating soot production. The behavior hinges on dispersant concentration, chemical nature, oil viscosity, and dielectric properties. Two types of polymeric-based ionic liquid-derived dispersants will be investigated, revealing their molecular architecture's impact on interparticle interactions and soot release. Techniques like small angle neutron scattering and dynamic light scattering reveal dispersant structural evolution. Electrophoretic mobility measurement uncovers carbon surface charge development. At low concentrations, dispersants exist as individual molecules, forming aggregates and micelles at higher concentrations. Excess uncharged micelles at higher concentrations may prompt attractive forces between particles, potentially increasing soot. This pioneering work explores into polymeric dispersants' molecular architecture in oil and its link to carbon stabilization, offering insights to enhance engine oil quality and environmental sustainability.
