NOVELTY - Solar heat-absorbing porous composite sheet comprises low-density polyethylene, ethylene vinyl acetate, calcium carbonate, zinc oxide, dicumyl peroxide, azodicarbonamide, and graphene nanosheets. USE - The composite sheet is useful for drying using solar energy. ADVANTAGE - The composite sheet: absorbs solar heat with high efficiency of 50% when microstructure combined with the graphene nanosheet; and helps bring about long-term use efficiency of 5 years, thus showing the stability in chemical structure and physical characteristics.
