題目:Hydrothermal and Solvothermal Synthesis for Composite Nanomaterials Preparation
LinkIconinformation

Abstract:
Nanocomposites have attracted a huge amount of interest due to their improved mechanical properties, dimensional stability, thermal/chemical stability, and electrical conductivity. Nanostructures are found to be of great significance because of their inherent properties such as large surface area to volume ratio and the engineered properties such as porosity, stability, and permeability. Composite material can achieve multifunctionality by combining the relevant, desirable features of different materials to form a new material having a broad spectrum of desired properties. Composite nanomaterials have been prepared by several techniques including sol-gel, precipitation, spray pyrolysis, hydrothermal, and solvothermal. In this presentation, hydrothermal and solvothermal techniques will be performed for preparation of CeO2-ZrO2 and ZnO-SiO2 nanocomposites because these techniques require simple equipment and easily controlled particle size and morphology by varying the synthesis conditions. The fabricated CeO2-ZrO2 nanocomposites with certain compositions could enhance their chemical and thermal properties to be used as electrolyte of Solid Oxide Fuel Cells. ZnO-SiO2 nanocomposites fabricated by solvothermal synthesis increased their chemical and optical properties for energy saving.

題目:Recycling of Thermoset Polymers and their Composites
LinkIconinformation

Abstract:
: Recycling of thermosets and their composites is the only viable and best option going forward on thermosets waste management demonstrated with the incontrovertible fact that there is technical feasibility within the effectiveness of the very diverse technologies available to date. Mechanical, thermal, chemical methods and depolymerization with supercritical fluids are revisited in this seminar. Recyclability is a concept that takes into account not only the properties of the material but the whole set of factors which can promote the natural course of action of a potential recycling market; as a definition, recyclability is the capability of a material to be recycled through its life cycle among the economical, technical, legislative and waste management circumstances that integrates the material to the recycling industry. While the use of bio-based and eco-friendly materials is an objective of technological development, better waste management technologies must be applied throughout the whole lifecycle for a sustainable use of thermosets and their composites.

題目:PET-RAFT for Advanced Polymer Synthesis
LinkIconinformation

Abstract:
PET-RAFT (photoinduced electron/energy transfer – reversible addition/fragmentation chain transfer) technology is a living radical polymerization methodology controlled by visible light and (near) IR light, which merges the tranditional RAFT polymerization with photoredox catalysis. In this technology, ppm amount of photoredox catalyst is employed to catalyze RAFT agent and generate radicals for subsequent polymerization, instead of external radical initiator in the traditional RAFT method. The RAFT agent plays the role of initiator, chain transfer agent and termination agent.
Although slight modification to RAFT polymerization was made, it brings many “green” and significant attributes to living radical polymerizations, including: (1) low energy consumption and mild reaction conditions, (2) spatial and temporal control on radical polymerization, (3) high oxygen tolerance, (4) versatile photocatalysts and (5) selective polymerization activation. In this talk, these benefits from PET-RAFT technology will be summarized and demonstrated by our recent results. This technology is contributing to the development of green chemistry and sustainable polymer manufacturing chemistry, but also providing opportunities for the innovation of new methods of organic and polymer synthesis.
