Small‐angle X‐ray and neutron scattering of temperature‐responsive polymers in solutions

Popis výsledku v původním jazyce

The most important feature of small‐angle X‐ray and neutron scattering (SAXS/SANS) methods is that they probe much smaller distances, usually 1‐100 nm, which can analyze different parts of macromolecules or polymeric nanoparticles using a contrast variation method. This chapter provides a brief and simple introduction to small‐angle scattering (SAS) experiment. SANS experiments confirm conclusions obtained for aqueous solutions: macromolecules of pNIPAM evidently shrink with approaching to phase transition. With appropriate copolymerization of pNIPAM with a cross‐linker, another type of nanoparticles could be prepared ‐ nanogel (microgel) nanoparticles. To summarize this brief SAS introduction, the transformation of temperature‐responsive polymer from a coil‐like conformation to a globular aggregate could be easily assessed by SAS techniques. An appealing application field studied by SAS is hybrid nanoparticles where already formed nanoparticles were modified with temperature‐sensitive polymers. The presence of a block with different nature (hydrophilic or purely hydrophobic) should modify the properties of temperature‐sensitive homopolymers.
