The present invention relates to a method for manufacturing a protein fiber, including an extension and contraction step of contracting or extending a protein raw fiber containing a protein by bringing the protein raw fiber into contact with a liquid or vapor; and a drying step of drying the protein raw fiber that has undergone the extension and contraction step while adjusting a length of the protein raw fiber to an arbitrary length.

Method and device for manufacturing protein fiber

A composite including a plurality of block copolymer chains dispersed in a base polymer, the block copolymer chains including a polymer block (A) and a polymer block (B) having lower affinity for the base polymer than that of the polymer block (A), wherein each of the block copolymer chains has the polymer block (A) at two or more locations of the block copolymer chain, and in at least some of the block copolymer chains, the polymer blocks (A) are at least partially located in the base polymer and the polymer blocks (B) are at least partially exposed from the base polymer.

Composite and production method thereof

A novel silicon compound capable of initiating radical polymerization is provided. The silicon compound is represented by the following general formula (1)A-Z&#x2014;S&#x2014;Z&#x2014;Si(OR)(R)&#x2003;&#x2003;(1)wherein A is a group capable of initiating radical polymerization, Zand Zare each independently a bivalent group that has at least a carbon atom, Rand Rare each independently an alkyl group having from 1 to 3 carbon atoms, and n is an integer of 1 to 3. A radical polymerization initiator comprising the silicon compound, and a polymer obtained by radical polymerization of a monomer with the radical polymerization initiator are also provided. Also provided is a complex having a polymer graft chain formed on a solid substance surface with the use of the silicon compound.
