The utility model discloses a kind of flat steel clamping assembly structure, including assembly groove and clamp, clamp includes two clamping pieces oppositely arranged along assembly groove extension direction, each clamping piece sequentially includes locking portion, clamping portion and with the stop portion of assembly groove cooperation, the clamping space for fixing flat steel is enclosed between the clamping portion of two clamping pieces and assembly groove;Clamping portion is L-shaped as a whole, including the first clamping section and the second clamping section of mutual connection, the end of first clamping section away from the second clamping section is connected with locking portion, the end of second clamping section away from first clamping section is connected with stop portion, locking portion and stop portion extend in direction of away from first clamping section, the end of first clamping section and locking portion compared with the end of first clamping section and second clamping section connection is inclined to the inside of clamping space. The above structure effectively improves the convenience, flexibility, reliability and versatility of flat steel clamping structure / device actual use.

The invention discloses a block copolymer binder and a preparation method and application thereof.The block copolymer binder is prepared through a template polymerization method and comprises a silicon-loving chain segment composed of repeating units of a silicon-loving monomer and a flexible chain segment composed of repeating units of a flexible monomer, the silicon-loving monomer is a monomer which has a polar group and can be connected with the silicon particles through chemical bonds. According to the segmented copolymer binder provided by the invention, the flexible chain segments and the silicon-philic chain segments are distributed at intervals on a molecular chain, so that the adhesion of the silicon-philic chain segments can be better played, the flexibility and processability of the binder are improved, and an electrode pole piece with good flexibility and stability can be prepared.
