我们报告了一个通用的平台,用于通过双胞模板合成具有高比表面积的聚合物dibreeb,由1,2-二棕榈酰磷酸胆碱(DPPC),1,2-二己酰磷酸胆碱(DHPC),和1,2-二棕榈酰磷酸甘油(DPPG)。原始的双胞(在没有单体或聚合物的情况下)产生各种明确的结构,包括盘,囊泡和穿孔板。在混合物中加入苯乙烯单体会导致双胞转变为层状结构。单体与DPPC和DPPG最初是混溶的,而聚合驱动聚合物的DHPC丰富的域,导致在一个聚合物dichroeb支持的结果的小角中子散射,差示扫描量热法,和透射电子显微镜。
We report a generalized platform for synthesizing a polymer nanoweb with a high specific surface area via a bicellar template, composed of 1,2-dipalmitoyl phosphocholine (DPPC), 1,2-dihexanoyl phosphocholine (DHPC), and 1,2-dipalmitoyl phosphoglycerol (DPPG). The pristine bicelle (in the absence of monomer or polymer) yields a variety of well-defined structures, including disc, vesicle, and perforated lamella. The addition of styrene monomers in the mixture causes bicelles to transform into lamellae. Monomers are miscible with DPPC and DPPG initially, while polymerization drives polymers to the DHPC-rich domain, resulting in a polymer nanoweb supported by the outcomes of small angle neutron scattering, differential scanning calorimetry, and transmission electron microscopy.
