Functional materials for sustainable technologies
We explore solar reflective, energy attenuation and icephobic coatings through the design and synthesis of asymmetric polymer chain and hybrid latex particle structures with the aim to reduce energy consumption. The innovative aspect of this study originates from formation of discrete assembling of clusters in nanoscale, which induce unusual properties, e.g. high reflectivity to near infrared radiation, enhanced viscoelastic trait and ostensible delays to icing on the respective coatings. In addition, the specifically designed asymmetric copolymer has been used to improve diesel fuel. Our latest study is about inorganic thin membranes, primarily carbonaceous and ceramic membranes supported by submicron-porous stainless steel substrates for performing nanofiltration aiming to separate low molecular weight solutes from organic solvents or water. This study stresses chemical control or modifications of the formation of carbon and ceramic matrices to attain high permeation flux and rejection, in which formulation of precursor and calcination atmosphere are scrutinized.
