The hydrophilic part is based on  naturally occurring proteins and as hydrophobic  block poly-n-butylacrylate was chosen. The block  copolymers are synthesized by using a bifunctional  initiator for NCA ring polymerization and  subsequently performing a Nitroxide Mediated Radical  Polymerization by macro-initiation of the peptide  block. Side reactions were occurring during NCA  polymerization, which were avoided by lowering the  temperature to 0 ºC. Calcium carbonate  crystallization experiments performed on the  hydrophilic block show that the resulting crystal  shape was affected. A new initiator based on SG1 was  developed which was successful in performing the  ring opening polymerization of the peptide monomer.  However, more research should be conducted to  improve control over the block copolymerization.  Cryo-TEM analysis of the resulting block copolymer  showed that a particle structure was formed which  confirmed that it is possible to synthesize a block  copolymer that is amphiphilic.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783838378732\"\u003e\u003ch3\u003eMimicking Nature to Control Calcium Carbonate Crystallization\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783838378732","offer_id":39469253394525,"sku":"9783838378732","price":49.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/50b1fa12-3dfb-4496-8c2d-a58bf92e77b2.jpg?v=1757656422","url":"https:\/\/shop.autorenwelt.de\/products\/biohybrid-nanocomposites-von-marloes-peeters","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
