Speech Title: Development of Advanced Cement-Based Materials through Incorporation of Nano Particles


Abstract: Recently, it becomes popular to achieve enhanced mechanical properties of cement-based materials through incorporation of nano particles. In this presentation, advanced cement-based materials through application of nanotechnology will be introduced. One example is to use cement to generate 5 nm nanoparticles which is utilized to enhance the mechanical properties of hydrogel. By adding 5-nm inorganic particles in organic matrix, hydrogels with the best all-round performance in the world has been successfully developed in aspects of strength, elastic recovery and ultimate stretch ratio. Also, by adding organic or inorganic nano particles into cement based materials, the flexural strength of the cement-based materials increased significantly. For cement paste, bending strength is increased by three times without lowing the compressive strength. Moreover, with newly developed inorganic-organic integrated nano particles, the hydration heat of cement-based materials can be reduced and their toughness will be improved without degrade their compressive properties. Finally, the high modulus concrete developed through the addition of nano particles will be introduced on its optimization in materials formulation, dimension stability behavior and structural performance.

Speech Title: Porous poly(ε-caprolactone) Microspheres via UV Photodegradation and RAFT Polymerization  


Abstract: Porous biodegradable microspheres were fabricated by successful RAFT polymerization of methyl vinyl ketone onto polycaprolactone and polylactide followed by an oil/water emulsion-evaporation method, then finally photodegradation of PMVK blocks by UV irradiation. Macro-CTA (chain transfer agent) was synthesized by reacting carboxylic acid terminated CTA, S-1-dodecyl-S’-(a,a’-dimethyl-a’’-acetic acid) trithiocarbonate (DDMAT) with hydroxyl terminated polycaprolactone, which was then used for the synthesis of triblock copolymer with methyl vinyl ketone (MVK). The synthesized triblock copolymers were characterized by FT-IR, 1H NMR spectroscopies. Gel permeation chromatography (GPC) was used to evaluate the molecular weight and molecular weight distribution and monitored the photodegradability of the block copolymers. The morphology of microspheres was spherical with smooth surfaces before UV irradiation. However, those from PCL-PMVK triblock copolymers had rough surfaces and porous structures after UV irradiation due to the photodegradation of PMVK blocks as a porous template. The porosity and shape of the microspheres and shape of microspheres were dependent on the PMVK contents and size of microspheres.
