Impact of 7:6 PEG/LDPE Ratio on the Structural Properties Prepared via Nanoprecipitation Method

This study investigates the effect of 7:6 weight ratio of polyethylene glycol (PEG) to Low density polyethylene (LDPE) on the structural properties of the resulting blend, synthesized by using nanoprecipitation method.The high PEG content (54 wt.%) was expected to enhance colloidal stability and surface wettability, potentially forming a hydrophilic shell around a hydrophobic LDPE core.Surface morphology observed through SEM, FTIR confirmed characteristic functional groups and indicated partial compatibility between PEG and LDPE through observed shifts in a peak intensity, XRD analysis showed a semi crystalline structure with reduced crystallinity compared to pure components.Additionally, UV-Vis spectroscopy indicated improved light absorption.The 7:6 PEG/LDPE blend demonstrates promising features for biomedical and packaging applications due to its tunable properties and ease of fabrication.
