“…Besides, the absorption intensity of the CO groups of PMAA also increases as shown in the A 1700 (CO) /A 2930 (CH) value. This increase in the absorption intensity of the carbonyl groups could be attributed to an increase in the dipole moment of the CO group while the two share in the hydrogen bond . The result confirms that PVA and PMAA could be cross‐linked using EG as both the solvent and cross‐linker at the same time, and the hydrogen bond interaction could be modulated by increasing cross‐linking time or temperature.…”

A novel hygroscopic hydrogel with air‐stable, recyclable, and stretchable properties is demonstrated in this study. The hydrogel is prepared by the simple polymer blends of two hydrophilic polymers, poly(vinyl alcohol) (PVA) and poly(methacrylic acid) (PMAA), using ethylene glycol as a hygroscopic solvent and cross‐linker. The PVA/PMAA hydrogel is highly stretchable after absorbing water molecules from the ambient environment as plasticizers. The hydrogel shows a high mechanical strength with a Young’s modulus of 0.75 MPa, linear region of 42%, and elongation of over 550% at break, and could be hydrolyzed by water then recast for high quality film for many times. The unique advantages of this hydrogel is further demonstrated by fabricating a stretchable organic memory device using the deoxyribonucleic acid as the memory layer on top of the hydrogel substrate. The device exhibits a write‐once‐read‐many‐times type behavior with a memory ratio of 104, retention time over 105 s, and mechanical durability over 30% strain.

“…Therefore, it will be suggested that the interaction undergoing in PY A/PMAA complex is possibly the intermolecular hydrogen bonding between OH and COOH groups, as suggested previously. 28,29 Since peaks 1 and 2 of CHOH carbon of PYA component are indicators of the intramolecular hydrogen bonding between the two consecutive units, the decrease in intensities of peaks 1 and 2 is probably attributable to the dissociation of the intramolecular hydrogen bonds between the two consecutive units of PYA. The upfield shift of COOH resonance ofPMAA may imply a break of intramolecular hydrogen bonding on complex formation with PYA.…”

ABSTRACT:Miscibility of poly(vinyl alcohol)/poly(methacrylic acid) complexes and poly-(vinyl alcohol)/poly(acrylic acid) blends is investigated by high-resolution 13C solid-state NMR method. Observed 13C spectra are discussed in terms of hydrogen-bonding effects on chemical shift. The results indicate that poly(vinyl alcohol) and poly(methacrylic acid) are intimately mixed on a scale of 20--30 A due to intermolecular hydrogen bonding to form equimolar-ratio complexes, For the poly(vinyl alcohol)/poly(acrylic acid) = l/l blend, the two polymers are also miscible, the crystalline phase of PVA is destroyed completely and no detectable domain can be observed for For two dissimilar polymers to be miscible, some exothermic intermolecular interactions should occur. Among many possible interactions, the hydrogen-bonding interaction has been studied extensively in recent years. [1][2][3][4][5][6] High-resolution 13e solid-state NMR is particularly useful for investigating hydrogenbonding interaction. Helpful information about the hydrogen bonding can be obtained through characteristic downfield shifts of 13e nuclei participating in hydrogen bonding. 7 ,8 Although such downfield shift induced by hydrogen bonding in solution reflects an average of bonded and non-bonded states, a rigid structure of hydrogen bonding in the solid state would cause further downfield shift. 9 ,IO Furthermore, the high-resolution 13e solidstate NMR method enables us to measure the relaxation time of I H spins of individual components of polymers through well-resolved 13e signals and to examine the domain structure and miscibility of polymer blends in the solid state. Ifpolymer chains are intimately mixed, fast spin diffusion among I H spins equalizes spin-lattice relaxation times of all protons. On the other hand, if the domain size of multi-phase structure of polymer blends is larger than the characteristic spin diffusion path length, the relaxation time can be observed separately for each component of polymers. In this work, we examine the hydrogenbonding interaction and miscibility of poly-(vinyl a1cohol)jpoly(methacrylic acid) (PV Aj PMAA) and poly(vinyl a1cohol)jpoly(acrylic acid) (PV AjPAA) systems. Since PV A, PMAA, and PAA all have strong hydrogen-bonding donors and acceptors, there would be inter-
