Macromolecular self-assembly and nanotechnology in China

Abstract

Macromolecular self-assembly refers to the assembly of synthetic polymers, biomacromolecules and supra-molecular polymers. Through macromolecular self-assembly, the fabrication of ordered structures at different scales, the control of the dynamic assembly process and the integrations of advanced functions can be realized. Macromolecular self-assembly and nanotechnology research in China has developed rapidly, from the early periods of follow-up at low to high level and progress into a stage of innovation and creation. This review selects some representative progresses achieved recently, aiming to reflect the current status of macromolecular self-assembly and nanotechnology research in China.

Molecular nanostructure and nanotechnology

“…of structures in a multi-component assembly and the influence of the environment on the kinetics of product formation. A variety of intermolecular interactions, such as hydrogen bonding, van der Waals forces, covalent and coordinate bonds, have been used successfully in the designed assembly of polymeric architectures (Xu et al [5]). Hydrogen bonding has the advantages of selectivity and directionality, and is an important interaction in many systems, e.g.…”

“…Complementary interactions between building blocks are the major factors in determining the stability of a molecular assembly and are the key to understanding the nature of a phase-separated molecular assembly, the heterogeneity of structures in a multi-component assembly and the influence of the environment on the kinetics of product formation.

Influence of molecular interplay on the HPAM/UR rheological properties in an aqueous solution

“…Moreover, several types of studies on the thermal cross-linking of carboxylate/ amine groups have already been reported and suggested the potential for temperature resistance. 22,23 In this study, the rheological properties of HPAM/UR solutions were explored via viscosimetry and rheometry using different detection models and temperatures. Dynamic light scattering was employed to directly analyze the hydrodynamic diameter.…”
