SURFACE-MODIFIED BIOFIBER, METHOD FOR PRODUCING THE SURFACE-MODIFIED BIOFIBER, LIQUID DISPERSION AND RESIN COMPOSITION COMPRISING THE SURFACE-MODIFIED BIOFIBER
SURFACE-MODIFIED BIOFIBER, METHOD FOR PRODUCING THE SURFACE-MODIFIED BIOFIBER, LIQUID DISPERSION AND RESIN COMPOSITION COMPRISING THE SURFACE-MODIFIED BIOFIBER
Method for producing surface-modified biofibers includes: obtaining a hydrophilic block (A) made of a first polymer and arranged on surfaces of biofibers by conducting a living radical polymerization of a first monomer in a solution containing the biofibers, the first monomer, and a solvent, and allowing the first polymer to be attached to the surfaces of the biofibers; and obtaining a hydrophobic block (B) made of a second polymer and stacked outside of the hydrophilic block (A) by adding a second monomer to the solution after obtaining the hydrophilic block, conducting a living radical polymerization of the second monomer, and polymerizing the second polymer onto growing ends of the first polymer. The biofibers, polymers, and solvent have surface free energies satisfying:; EBFEAEBES (1);[EBF represents the surface free energy of the biofibers, EA that of the first polymer, EB that of the second polymer, and ES that of the solvent].
