Fiber-shaped polymer vitrimer was challenged in this work using commercial maleic anhydride-grafted-high density polyethylene as the matrix and hexanediol as the crosslinker for facile preparation of HDPE vitrimers. The impact of dynamic covalent bonds on the formation of aggregate structures during fiber-shaped vitrimers processing was revealed.
Vitrimers have emerged as a prominent research area in the field of polymer materials. Most of the studies have focused on synthesizing polymers with versatile dynamic crosslinking structures
while the impact of chemical structure on aggregate structure of vitrimers
particularly during polymer processing
remains insufficiently investigated. The present study employed commercial maleic anhydride-grafted-high density polyethylene (M-
g
-HDPE) as the matrix and hexanediol as the crosslinker to facilely obtain fiber-shaped HDPE vitrimers through a reaction extrusion and post-drawing process. Through chemical structure characterization
morphology observation
thermal and mechanical properties investigation
as well as aggregate structure analysis
this work revealed the influence of dynamic bonds on the formation of aggregate structures during fiber-shaped vitrime
rs processing. A small amount of dynamic bonds in HDPE restricts the motion of PE chain during melt-extruding and post-drawing
resulting in a lower orientation of the PE chains. However
lamellar growth and fibril formation during post-drawing at high temperature are enhanced to some extent due to the competition between dynamic bond and chain relaxation. The uneven morphology of fiber-shaped HDPE vitrimers can be attributed to the stronger elastic effect brought by dynamic bonding
which plays a more dominant role in determining the mechanical properties of fiber-shaped vitrimers compared to aggregate structure.
