Preparation of novel polypropylene oligomer compatibilizer for polypropylene/microfibrous cellulose composite and its addition effect

Abstract

Polypropylene (PP) oligomer was prepared by combination of photodegradation with a TiO 2 /polyethylene oxide and methyl linoleate (ML) graftpolymerization. The gel permeation chromatography and nuclear magnetic resonance measurements showed that it was an oligomer compound composed of PP main chain and ML oligomer side one. A compatibilizer performance of the PP oligomer was studied using a PP/microfibrous cellulose (MFC) composite. The effects of the loading on the morphology and tensile properties of PP/MFC composite were investigated as compared with those of the maleated PP (MAPP) loading. The PP oligomer loading brought about good dispersity of the MFC in the PP matrix. Young's modulus value of 0.75 % PP oligomer loading composite was increased to 300 % as compared with that without the loading. The dispersity and modulus increment rate were superior to the MAPP loading. The excellent compatibilizer performance was due to good miscibility with the PP matrix.Electronic supplementary material The online version of this article (

Interfacial Adhesion of Polylactic Acid on Cellulose Surface: A Molecular Dynamics Study

“…With its low cost, reproducibility, and interesting mechanical properties, cellulose has gained wide attention in high performance composite materials. , Cellulose is added to the polymer as a filler to enhance the mechanical properties of the material or to reduce the cost of the final product. It has been used to strengthen polypropylene, , polysulfone, poly­(methyl methacrylate), polylactic acid, , and other polymer systems . The cellulose–cellulose and cellulose–matrix interfaces in these materials have impressive properties, and the thermodynamic stability and mechanical properties of the resulting system depend on the strength of the interaction of the cellulose with the matrix.…”

Photocatalytic Conversion of Plastic Waste: From Photodegradation to Photosynthesis

“…Apart from PE and PP, the photodegradation of other plastic waste such as PS and PVC have also been widely investigated. [134][135][136][137][138][139][140][141][142][143][144] For example, Zhang and co-workers recently reported the complete mineralization of PS microplastics by 30 nm TiO 2 nanoparticle photocatalysts fabricated with Triton X-100 as a nonionic surfactant (Figure 6a). [143] Mass spectrometry and in situ diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) experiments were performed to understand the photodegradation mechanism.…”
