Abstract null null To develop an adequate matrix polymer for agricultural or packaging applications, thermoplastic starch (TPS)/chitosan composites were prepared in a wide composition range either by injection moulding or in an internal mixer followed by compression moulding. Chitosan behaves as filler forming dispersed structure in TPS samples prepared by thermomechanical methods without any additional acid. In the TPS composites chitosan has a considerable reinforcing effect. Regardless of the...

Abstract null null Biobased plasticizers for polymers is a necessity to replace conventional phthalates based plasticizers. In the present study, Citrullus lanatusseed oil (ECLO) was epoxidized in a magnetically stirred reactor. Polyvinyl chloride (PVC) films were synthesized using different concentrations of ECLO. At 40% of ECLO, films showed better surface morphology and exhibited maximum strength and elongation at break. Plasticized PVC film shown tensile strength of 18.6 MPa and elongation a...

Abstract null null According to the physical and chemical multifield coupling effects on anticorrosive coatings under marine atmospheric environments, the correlations between various environmental factors were analyzed, and a multifactor coupling accelerated test spectrum of the marine atmospheric environment was designed. Moreover, an ultraviolet (UV)/salt spray coupling acceleration test chamber was also designed and prepared, and a multifactor coupling accelerated test method for marine atmo...

ABSTRACT Zinc oxide (ZnO) nanorods were grown on the surface of a polypropylene (PP) nonwoven fabric (NWF) using the low-temperature hydrothermal method. The finishing process was investigated, and the prepared PP NWF was characterized. Results of the scanning electron microscopy, Fourier transform infrared spectroscopy, X-ray diffraction, anti-ultraviolet (UV) properties, and energy dispersive spectrometry indicate that the ZnO nanorods can be synthesized and uniformly coated on the surface of ...

Abstract The aim of this study is to evaluate the suitability of bioplastic bottles for wine packaging. The wine is largely packaged in glass bottles, although alternative solutions such as laminate, plastic and bag-in-box packaging are decidedly widespread on the market by virtue of their ease of use and low cost, especially for the so-called entry-level products. However, packaging involving the partial or exclusive use of plastic is the subject of discussion in the scientific community, by vi...

Abstract Different crystal planes of nanocrystalline often displayed diverse physical and chemical properties. In this paper, the effects of nano-ZnO with two kinds of crystal planes on crystallization, thermal stability and mechanical properties of PLLA were investigated. The results show that the (1010) planes with no-polar and low surface energy increased the chain mobility of PLLA chain, showed a plasticizing effect; the glass transition temperature, melt and cold crystallization temperature...

Abstract null null Barocaloric effect in polymers is barely recognized and limited to a few reports in the literature. This effect consists of a thermal response of the material when a hydrostatic pressure is applied, allowing its application in the field of solid-state cooling. In this study, the barocaloric effect was investigated for a commercial polyurethane rubber (PU) subjected to three heat treatment temperatures (60, 100, and 115 °C) for 16 h to assess the limiting condition for this app...

Abstract Composite materials have widened their application range in recent years. The polymeric composite reinforced with carbon fibers can be described as a high-performance structural material which merges two important features: low weight and mechanical stability. Carbon fiber production which uses polyacrylonitrile as precursor is composed of many stages such as polymerization, spinning, thermal stabilization, carbonization, and surface treatment. Thermal stabilization is the critical stag...

Abstract Anchoring phosphotungstic acid (HPW) on insoluble inorganic fillers is a facile and effective approach to suppress its leakage in the proton exchange membrane. In this work, we introduced β-cyclodextrin (β-CD) on halloysite nanotubes (HNTs) with the aid of polydopamine coating to prepare water-insoluble β-CD-DHNTs, which was dispersed in the SPEEK matrix to anchor HPW. Both HPW and β-CD-DHNTs are well dispersed in the SPEEK matrix because of the hydrogen bonding complexation between [PW...
