Organic–Inorganic Copolymerization for a Homogenous Composite without an Interphase Boundary

Abstract

Ionic oligomers and their crosslinking implies ap ossibility to produce novel organic-inorganic composites by copolymerization. Using organic acrylamide monomers and inorganic calcium phosphate oligomers as precursors, uniformly structured polyacrylamide (PAM)-calcium phosphate copolymer is prepared by an organic-inorganic copolymerization. In contrast to the previous PAM-based composites by mixing inorganic components into polymers,t he copolymerized material has no interphase boundary owing to the homogenous incorporation of the organic and inorganic units at molecular level, resulting in ac omplete and continuous hybrid network. The participation of the ionic binding effect in the crosslinking process can substantially improve the mechanical strength;the copolymer can reachamodulus and hardness of 35.14 AE 1.91 GPaa nd 1.34 AE 0.09 GPa, respectively,w hich are far superior to any other PAM-based composites.Supportinginformation and the ORCID identification number(s) for the author(s) of this article can be found under: https://doi.

Novel nanomaterial–organism hybrids with biomedical potential

“…Precursor‐induced mineralization participates in the control of mineralization by providing a feasible strategy for the construction of nanomaterial‐integrated organisms with an interface suitable for biomineralization. (Shao et al, 2019; Yadong Yu et al, 2019; Y. Yu et al, 2020).…”
