海报摘要

Temperature is one of the extremely significant factors responsible for modifications mostly in physical but also chemical properties of some particular matter. In the present study, we theoretically analyzed the thermo-responsive behavior of Ag-p (N-isopropylmethacrylamide) hybrid microgels. We employed the classical Maxwellian distribution function concerning the velocity of spherical silver nanoparticles inside the microgel’s network. The behavior of the distribution function relative to the temperature represents that the distribution function still obeys the Maxwell-Boltzmann law even at low temperatures. Further, the diffusion coefficient, probability density, surface tension, and surface energy of silver nano-particles are numerically evaluated and then graphically illustrated.
