Latest Patents
Hirokawa's latest patents include innovative processes for manufacturing porous polymers. The first patent describes a method for creating a porous polymer that contains numerous voids in its interior. This polymer boasts a small apparent specific gravity and excels in water-absorbing properties, permeability, and elasticity. The process involves forming an oil-in-water (O/W) emulsion using a water-soluble surfactant, where the inner phase is hydrophobic and the outer phase contains at least one water-soluble polymerizable monomer. The O/W emulsion is then added to a hydrophobic dispersing medium containing an oil-soluble surfactant to create an O/W/O emulsion, which is subsequently polymerized.
The second patent mirrors the first in its focus on manufacturing porous polymers with similar advantageous properties. The detailed steps of the process ensure that the resulting material is both effective and efficient for various applications.
