Article Synopsis
- - The study presents petal-like graphene porous films designed with dendritic and honeycomb pores to effectively combat electromagnetic pollution, achieved through a controlled phase inversion process.
- - By modifying the graphene with PVP K30, the distribution is improved, leading to a 170% increase in electromagnetic shielding effectiveness and enhanced thermal conductivity by 104%, compared to films without this modification.
- - The resulting porous films also show significant improvements in mechanical properties, with tensile strength rising to 6.9 MPa and elongation at break increasing by 131%, while successfully preventing graphene agglomeration.
Heavy fractions (e.g., asphaltene and resin) can easily be subjected to physical aggregation and chemical coking reaction through molecular force in the process of lightweight processing and use of coal tar (CT), such that the normal processing and use can be affected.

These should be removed before coal tar is hydrogenated. In this study, with the acid refining method, the effects of three polyether demulsifiers (i.
