ABSTRACT:
At least one of a hollow particle14, a porous particle24, and a solid particle34having the pores18, 28, 38on the surface thereof is subjected to plasma irradiation under a reduced pressure while changing plasma irradiation intensity and/or the degree of vacuum. After the plasma irradiation, at least one type of monomer is graft polymerized onto the surface of the plasma irradiated particle by contact between the at least one type of monomer and the particle so as to substantially fill the pores18, 28, and38of the particle with grafted polymers12of the monomers.
