“…PEO based PUs are expected to show the highest phase mixing, while PDMS based polyureas are expected to display excellent microphase separation. This has also been demonstrated experimentally and has been reported in the literature extensively[1,4,5,19,[42][43][44][45].…”

“…This can be achieved through the synthesis of segmented copolymers based on an apolar PDMS soft segment (SS) alternated with a polar self-associating hard segment (HS). Yilgor et al [3] , [4] were the first to synthesize this kind of copolymers with a regular alternation of PDMS and bis-urea segments (i.e. without chain extender).…”

“…For example, the introduction of small, low-valence anions (such as Cl -, F -) can promote the formation of the rutile phase in TiO2. However, the introduction of high-valence anions (such as PO4 3-and SO4 2-) with large radii is not conducive to the transformation of anatase to rutile [135,136]. The percentage of anatase in the surface region can increase from 2% to 75% with the increase of the content of SO4 2-in TiO2 from 0 to 3 wt%.…”
