- Abstract
- Basic physical and chemical properties of particles of different dimensions: nano-, smart and macro- are considered. It is shown that particles and their properties differ in quantity of end and middle groups which have different chemical structure. If chain length (molecular mass) large, then contribution of end groups in properties and structure macroparticles can fail to take into account while contributions of end and middle groups in nano- and smart particles are compared. It is known that freedom of rotation of bonds around single chemical bonds which absent in nanoparticles is reached in macroparticles. It is established that in smart particles transition from absence of bonds rotation freedom around single chemical bonds to beginning, springing up and striving for limit of bond rotation freedom R is observed. It is noted that on account of bonds rotation freedom change and consequently entropy new physical and/or chemical processes mainly entropy character and high-elasticity state (in no-solvent condition) occur in one-dimensional smart (oligomer) particles.
