One third of the life of a person spends in sleeping, and the mattress and the pillow are the supporting platforms for sleeping of the human body, and the sleeping quality of the human body is directly influenced.

In the filling materials of pillows or mattresses in the market at present, latex and memory cotton occupy most of the market share. The latex or the memory foam has better comfort, but is easy to generate stuffy feeling, especially in summer, and the reason is that moisture is discharged every night, which is equivalent to water of 200-300ml, and if the moisture is discharged in time, mites and other bacteria grow on the pillow or the mattress, so that a good sleeping microenvironment cannot be provided for a human body, and the damage is caused to the skin of the human body. In addition, the natural latex has limited raw material sources, and petrochemical raw materials are increasingly exhausted, so that natural renewable raw materials can gradually replace petrochemical raw materials such as memory foam, latex and the like. In addition, the memory foam in the market has the defects of poor supporting performance and easy tearing, cannot have a good supporting effect on the head of a person, is easy to damage in the using process and causes the reduction of the service life. These problems are affecting the quality of sleep of the human body and need to be solved.

The luffa seed is used as agricultural and forestry waste, has high oil content up to 25-39%, is used as a renewable raw material, and has far lower cost than petrochemical raw materials. Meanwhile, related researches show that the luffa seed oil also has certain antibacterial, anti-mite and sleep-aiding effects.

The graphene is a new material formed by tightly stacking sp2 hybridized and connected carbon atoms into a single-layer two-dimensional honeycomb lattice structure, has excellent optical, electrical and mechanical properties, and has important application prospects in the aspects of materials science, micro-nano processing, energy, biomedicine and the like. Among them, the multilayer graphene has better lubricity due to weak interaction (van der waals force) between atoms between layers thereof. Related researches show that the plasma functionalized modification is beneficial to improving the dispersion stability of the multilayer graphene in the vegetable oil.

Therefore, if the sponge gourd seed oil modified by the plasma functionalized multi-layer graphene and the polyether polyol are mixed and foamed to prepare polyurethane foam as the pillow filling material, the production cost can be reduced, certain ventilation and sleep-aiding effects can be given to the sponge filling material, and a good sleep microenvironment is created. Meanwhile, in the filling material, the viscosity of a foaming mixture system can be reduced by the plasma functionalized multilayer graphene modified luffa seed oil, the foam holes become more uniform, the pore structure is richer, the gas in the sponge can be discharged more easily, and the foam surface presents the texture of the latex; the addition of the fatty acid carbon chain of the luffa seed oil can generate a crosslinking effect with a polyurethane molecular chain, and simultaneously open pores of foam are generated. Therefore, the air permeability of the loofah seed oil latex-like sponge is improved, and the tear resistance of the loofah seed oil latex-like sponge is improved to a certain extent.
