“…In addition, there are two thermal degradation stages of WPU0: the first stage in which the maximum weight loss temperature is 329°C (T 1max ) which is the maximum thermal decomposition temperature of the hard segment in the WPU. The second stage is when the maximum weight loss temperature is 391°C (T 2max ) which is the maximum thermal decomposition temperature of the soft segment in the WPU, and this is consistent with the thermal decomposition characteristics of the typical soft and hard segments of PU [25,26]. When T 1max and T 2max of WPU0 are compared, there is an increase in the T 1max of WPU2 and WPU4 to 6°C and 17°C and an increase in the T 2max of WPU2 and WPU4 to 9°C and 21°C, respectively.…”

In this study, a waterborne polyurethane (WPU) is synthesized by using polytetramethylene ether glycol (PTMEG) to form the soft segment, 1,4-butanediol (BDO) as the chain extender, n-methyldiethanolamine (MDEA) as a hydrophilic chain extender, and isophorone diisocyanate (IPDI) to form the hard segment. Furthermore, the modified cationic WPU emulsion and its films are created through a reaction between the WPU and a linear polyether-blocked amino silicone (LEPS), which is an organosilicon compound that imparts flexibility. The properties of the structure and formed WPU films are then characterized by using Fourier transform infrared spectrometry, a thermogravimetric analysis, atomic force microscopy, X-ray diffraction, and X-ray photoelectron spectroscopy, as well as by measuring the water contact angle, testing the water absorption, etc. It is found that, with an increase in the LEPS content in the WPU, the particle size of the modified WPU emulsion is increased, the WPU films are more flexible, and the resistance of the modified WPU films to heat and water are increased, while the crystallinity is reduced. The polysiloxane chain segment, which is added to the LEPS-modified WPU emulsion, is significantly enriched on the surface of the modified WPU films, while there are no adverse effects of the LEPS-modified WPU emulsion on the adhesive force between the WPU and substrate. When the LEPS content of the WPU is 14.0 wt%, the modified WPU emulsion and film provide the best performance.

“…Figure (a) compares the FTIR spectra for PUMA prepolymers and PUMA polymer; the C  C bands from the prepolymer disappeared upon UV‐curing . This C  C bands was likely to be from methacrylate groups of PUMA prepolymer though the actual mechanism was not known because of its proprietary mixture.…”

Proprietary mixture of polyurethane methacrylate (PUMA) and off-stoichiometry thiol-ene (OSTE-80) are evaluated as two possible polymeric substrates to prototype microfluidic biochips. Because of their lack of biocompatibility, PUMA and OSTE-80 are modified by argon (Ar) or nitrogen (N 2 ) plasma treatment to introduce nitrogen moieties that are highly polar and conducive for cell attachment and growth. XPS and water contact angle measurement show that these nitrogen groups are relatively stable in the plasma-treated PUMA and OSTE-80 in spite of the hydrophobic recovery and volatilization of nitrogen moieties during air ageing for 15 days. This stability can be attributed to their high degree crosslinking that is reflected by the increase of elastic modulus of PUMA and OSTE-80 during their air ageing. These results show that Ar and N 2 plasma-treated PUMA and OSTE-80 possess the necessary physical and chemical properties to be evaluated further to develop microfluidic biochips for biological applications.

“…Another possibility to achieve desired properties of polymers is the preparation of composites or hybrid materials (HMs) by incorporating an inorganic filler or an inorganic polymer, such as polysiloxane . An important factor for hybrid materials quality is the homogeneous distribution of the inorganic component within the organic polymer matrix or the formation of interpenetrating networks of the corresponding components …”

“…[2,[10][11][12][13] An important factor for hybrid materials quality is the homogeneous distribution of the inorganic component within the organic polymer matrix or the formation of interpenetrating networks of the corresponding components. [14] An innovative way for the fabrication of PFA-silica nanocomposites is the method of twin polymerization (TP). In this special polymerization process interpenetrating networks consisting of inorganic and organic polymers can be generated in only one reaction step by polymerization of a single source monomer, the so-called twin monomer (TM).…”

The trifunctional (3‐aminopropyl)‐tris‐furfuryloxysilane monomer (1) is able to undergo both twin polymerization and reaction with electrophilic compounds such as isocyanates. 1 can be readily synthesized from 3‐aminopropyptrimethoxysilane (APTMS) and furfuryl alcohol (FA). The reaction of 1 with three different aromatic isocyanates, namely phenyl isocyanate, diphenylmethane‐4,4′‐diisocyanate (MDI), and a prepolymer consisting of MDI end‐capped polytetramethylene ether glycole (PTMEG), to the corresponding substituted urea derivatives is presented. Three urea derivatives 1‐phenyl‐3‐(3‐tris‐furfuryloxysilyl)propylurea (2), diphenylmethan‐4,4′‐bis[3(tris‐furfuryloxysilyl)propyl]urea (3), bis[3(tris‐furfuryloxysilyl)‐propyl]urea‐capped PTMEG‐MDI‐prepolymer (4) as well as 1 were polymerized to multicomponent organic/inorganic hybrid materials in a one step procedure using methane sulfonic acid as catalyst. The simultaneous formations of poly furfuryl alcohol and polysiloxane networks within the hybrid material are proven by means of solid‐state NMR spectroscopic measurements. The homogeneous distribution of silicon within the solidified hybrid materials is analyzed by scanning electron microscopy, energy dispersive X‐ray spectroscopy, and high‐angle annular dark field‐scanning transmission electron microscopy (HAADF)‐STEM. Homogeneous nanostructured hybrid materials with silicon cluster sizes in the range of 2 nm have been obtained by polymerization of the urea derivatives 2, 3, and 4.
