This article elaborates on the poly(ethylene terephthalate) (PET) recycling by dissolution–reprecipitation method and then fabrication and examination of its nanocomposites (NC)s with poly(vinyl alcohol) grafted ZnO nanoparticles (NP)s which was fabricated through blending procedure and solution casting process.
This study presents fabrication of recycled poly(ethylene terephthalate) (rPET) reinforced with decorated multiwalled carbon nanotubes by carbon quantum dots (MWNT/CQD)s. The resulting MWNT/CQDs and rPET/MWNT/CQD composites were characterized by various analyses.
Polymer/graphene nanocomposites (NCs) have gained increasing attention owing to their unique properties. In this study, to improve the physicochemical features of poly(vinyl alcohol) (PVA), crosslinked PVA/functionalized graphene oxide (FGO) films were prepared, using glutaraldehyde (GA) as crosslinking agent.
Firstly, Ag nanoparticle (Ag-NP) was synthesised with environmentally-friendly and green media extracted from Rosmarinus officinalis plants. The structure of Ag-NP was confirmed with the absorption peak related to the Surface Plasmon Resonance at 432 nm through UV-Vis analysis. Subsequence, Ag-NP was composited with pre-synthesised vitamin B9 (VB9) intercalated Layered Double Hydroxide (VB9-LDH) and Ag@VB9-LDH with different percentages was incorporated in the chitosan (CS) as bio-polymeric matrix.
Chitosan nanocomposites containing 2, 5, 8 wt% of calcium carbonate-γ-aminopropyl triethoxy silane (CS/CC-ATS NCs) were prepared by ultrasonic irradiation.
Crosslinked Chitosan/nitrogen doped-graphene quantum dot nanocomposites (CCS/NGQD NC) with 10 wt% of glutaraldehyd as crosslinker were fabricated under ultrasonic cavitation. Structure and physicochemical properties of the prepared nanocomposites (NC) were systematically characterized by a number of techniques. The swelling capacity of the crosslinked films in the simulated intestinal (pH 7.4) media was evaluated. However, rate of water ingress of specimens was nearly same, but, the CCS/NGQD NC 8 wt% showed the more water absorption ability than the CCS.
Vitamin B9 (VB9) as a biological molecule was used for the intercalation of MgAl-layered double hydroxide (LDH) which can increase the active sites and organic nature of LDH samples.
