“…The peak centered at 1010 cm À1 was clear evidence of the formation of the ZnÀOÀSi bond. 32 The IR spectrum of CdTe/ZnO400 (Figure 8A, curve c) showed significant differences with respect to that of the APS/ ZnO400 sample, mainly in the low wavenumber region. In particular, a band at 1570 cm À1 , strongly overlapped to the bending modes of the ÀNH 3 + group at 1615À1580 cm À1 , is formed.…”

ZnO nanosheets were synthesized through thermal decomposition of the Zn4CO3(OH)6·H2O precursor at increasing temperatures (i.e., 300, 400, and 500 °C), and a multidisciplinary characterization (carried out by X-ray diffraction, SEM and TEM microscopy, FTIR, diffuse reflectance UV–vis and photoluminescence spectroscopy, TGA, and nitrogen adsorption) allowed us to describe the dependence of the physicochemical properties of the final materials on the precursor decomposition temperature. Due to its interesting physicochemical properties (good electrical conductivity, adequate specific surface area, and significant concentration of surface OH groups suitable for sylilation reactions), the ZnO sample, prepared by thermal decomposition of Zn4CO3(OH)6·H2O at 400 °C (named ZnO400), was selected as the host solid for the introduction of guest luminescent CdTe nanocrystals. The modification of the ZnO surface with CdTe allowed us to change the optical properties of the final solid, resulting in a tuning of emission properties of the ZnO nanosheets.

“…Bands at 1100 and 890 cm –1 can be attributed to the asymmetric and symmetric stretching of Si–O–Si groups, respectively, deriving by a partial condensation of the organosilanes used to modify the ZnO400 surface. The peak centered at 1010 cm –1 was clear evidence of the formation of the Zn–O–Si bond …”

“…[15a,51] OFAM plays a double role during the transformation of inorganic NPs into their hybrid form, in which À SiÀ OÀ bonds based protective layer form around the inorganic NPs via hydrolysis or condensation of alkoxy groups, while their terminal functional groups take part in pre/postfunctionalization of BPHU. Due to the easy and rapid process, researchers are fascinated to hybrid the inorganic NPs with OFAM such as aminopropyltrimthoxysliane (APTMS), [41] aminopropyltriethoxysliane (APTES), [59] cholorosilanes, [60] trialkoxysilanes [61] and 3-glycidoxypropyltrimethoxysilane. [62] These coupling agents are chemical substances that create a chemical bridge between the polymer matrix and the reinforcement.…”

New and emerging demand for polyurethane (PU) continues to rise over the years. The harmful isocyanate binding agents and their integrated PU products are at the height of environmental concerns, in particular PU (macro and micro) pollution and their degradation problems. Nonisocyanate poly(hydroxy urethane)s (NIPUs) are sustainable and green alternatives to conventional PUs. Since the introduction of NIPU in 1957, the market value of NIPU and its hybridized materials has increased exponentially in 2019 and is expected to continue to rise in the coming years. The secondary hydroxyl groups of these NIPU's urethane moiety have revolutionized them by allowing for adequate pre/post functionalization. This minireview highlights different strategies and advances in pre/post-functionalization used in biobased NIPU. We have performed a comprehensive evaluation of the development of new ideas in this field to achieve more efficient synthetic biobased hybridized NIPU processes through selective and kinetic understanding.
