Abstract

Abstract: Degreasing cotton was used to prepare an initiator for surface-initiated atom transfer radical polymerization (SI-ATRP).Subsequently,SI-ATRP of tetrahydrofurfuryl methacrylate (THFMA) and lauryl methacrylate (LMA) was carried out in the presence of sacrificial initiator (EBiBr) to prepared self-reinforced CNCs based thermoplastic elastomers (CTPEs).FT-IR,¹H NMR and GPC were applied to characterize the structure of CTPEs.DSC analysis showed that the glass transition temperature (T_g) of CTPEs was increased from-0.04℃ to 22.58℃ with the increasing of THFMA content.Mechanical properties test showed that the tensile strength was increased from 0.14 MPa to 6.17 MPa with the increasing of THFMA content in the feeding.And compared to the linear copolymer P (LMA-co-THFMA) which has the same THFMA/LMA composition,the tensile strength of CTPEs was increased by 3 times,which indicated that CNCs could greatly improve the mechanical properties of CTPEs.

Key words: SI-ATRP, cellulose nanocrystals (CNCs), thermoplastic elastomer
