<p>➀ This study explores the development of printable graphene inks using polypropylene carbonate (PPC) as a dispersant, suitable for low-surface-tension solvents and low-temperature processing.</p><p>➁ The inks exhibit improved dispersion stability and redispersibility, with printed graphene layers showing precise geometries and thickness control.</p><p>➂ The electrical conductivity of the printed graphene reaches approximately 2.05 × 10^4 S/m after annealing, making PPC a compatible material for flexible and heat-sensitive substrates.</p>
