Abstract

Stimuli-responsive polymeric nanostructures are compelling vectors for a wide range of application opportunities. The objective we sought was to broaden the array of self-assembling amphiphilic copolymers with stimuli-responsive characteristics by introducing a hydrophilic tunable monomer, (2-dimethylamino)ethyl methacrylate (DMAEMA), together with a hydrophilic one, lauryl methacrylate (LMA), within linear and branched copolymer topologies. Size exclusion chromatography was used to evaluate the resultant linear and hyperbranched copolymers' molecular weight and dispersity, and FT-IR and ¹H-NMR spectroscopy techniques were used to delineate their chemical structure. The structural changes in the obtained self-organized supramolecular structures were thoroughly investigated using aqueous media with varying pH and salinity by dynamic light scattering (DLS), fluorescence spectroscopy (FS), and transmission electron microscopy (TEM). The nanoscale assemblies formed by the amphiphiles indicate significant potential for applications within the field of nanotechnology.

两亲线性和超支化聚电解质的一锅合成及其在水溶液中的刺激响应自组装。

刺激响应聚合物纳米结构具有广泛的应用前景。我们寻求的目标是通过在线性和支链共聚物拓扑结构中引入亲水可调单体（2-二甲氨基）甲基丙烯酸乙酯（DMAEMA）和亲水单体甲基丙烯酸月桂酯（LMA）来扩大具有刺激响应特性的自组装两亲性共聚物的阵列。用粒径排除色谱法评价所得线性和超支化共聚物的分子量和分散性，并用FT-IR和1H-NMR技术描述其化学结构。通过动态光散射（DLS）、荧光光谱（FS）和透射电子显微镜（TEM）等方法，研究了在不同pH和盐度的水介质中获得的自组织超分子结构的结构变化。两亲体形成的纳米级组件在纳米技术领域具有巨大的应用潜力。

期刊介绍： Polymers (ISSN 2073-4360) is an international, open access journal of polymer science. It publishes research papers, short communications and review papers. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. Therefore, there is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. Polymers provides an interdisciplinary forum for publishing papers which advance the fields of (i) polymerization methods, (ii) theory, simulation, and modeling, (iii) understanding of new physical phenomena, (iv) advances in characterization techniques, and (v) harnessing of self-assembly and biological strategies for producing complex multifunctional structures.
