Atomic force microscopy sample stage

Properties of mixed polymer compositions are determined by many factors, among which in the first place should be allocated phase sfructure (ratio and the size of the phase domains). Therefore, at the first stage of the research attention has been paid to study the stmcture of formed compositions. In the investigation of samples with a low content of PHB (10-30% by weight) has been found that it forms a discontinuous phase, i. e., distributed in a continuous matrix PIB as separate inclusions of the order of 1-2 pm. The results of atomic force microscopy for the composition ratio of PHB-PIB 20 80 were shown in Figure 2.1.
