Synergetic Self-assembly Of Functional Amphiphiles And Block Copolymers

Polymer nanomaterials can be effectively constructed via self-assembly process.These novel nanomaterials have broad application prospects in many high-tech research fields such as biomedical applications,photoelectric materials and smart materials,etc.Development of self-assembly strategy will further open a door to create novel materials with new nanostructures and functions for polymer materials.Here,we report a new synergetic strategy of self-assembly with liquid crystalline polymer in presence of amphiphilic molecules.By this way,functional amiphiphiles co-assembly with polymers to generate new assembled nanostructures.Also,the functions from amiphiphiles were introduced into complex micelles and created a series of functional polymer nanomaterials.This work is divided into two parts:(1)A series of amphiphilic molecules were designed and synthesized by connecting OEG-based dendrons and cholesterol with different linkers.Their physicochemical properties were studied by ~1H NMR,DSC,POM and SAXS.The self-assembly behavior of the amphiphilic molecules and their functional properties of thermoresponse,reduction-response and chirality were also studied in detail.(2)Co-self-assembly behaviors of functional moleculars in presence of two liquid crystal copolymers were studied.In detail,assembly conditions and effects such as solvent,temperature,combination ratio,also the chemical structure of amphiphiles and polymers were investigated.Based on an assumption,that is the functions of thermoresponse and chirality from amiphiphiles were introduced into the co-assembled micelles.The stimuli-responsive behavior of complex micelles with controlled structures were exhibited.In addition,all of amphiphiles,polymers and assemblies were explored in cell experiments,their excellent biomimic properties make them as potential candidates to be applied in the fields of biomedicines,biomaterials and smart materials.
