The Influence of Side-chain Polyhedral Oligomeric Silsesquioxane-containing Polymer's Degree of Polymerization on Its Crystal Structure
The crystallization behavior of polymers is closely related to their material properties,representing an important fundamental research area in polymer physics.Cluster-containing polymers are a newly emerging class of hybrid polymers that combine the rich functionality of nanoclusters with the excellent processability of polymer materials,providing new avenues for the development of advanced hybrid materials.In this study,polyhedral oligomeric silsesquioxane(POSS)cluster-containing polymers with side chains were investigated.A series of precise polymers with different degrees of polymerization were synthesized through precise chemical techniques to control their molecular parameters.Single crystal growth was conducted in solution,and a systematic analysis of their morphology,structure,and thermodynamic parameters was performed to investigate the influence of polymerization degree on their crystallization behavior.Within the scope of this study,it was found that the degree of polymerization did not affect the crystal structure of single crystals,and there was no significant correlation with lamellar thickness or melting temperature.The growth of single crystals from solutions was greatly influenced by kinetic factors such as solvents,temperature,and concentration fluctuations,indicating that they were not thermodynamically stable crystals.
