In addition, FTIR spectrum of PVA nanofiber is shown inDie Straenleuchten LED E27 Sind Eine Art Leistungsstarke Lampen. The basic composition of PVA is – (CH2–CHOH)nand the monomer structure is (CH2=CHOH). Coffee Cup with Lip (SH-PM06)clearly reveals the major peaks associated with PVA. The peak observed at approximately 1100 cm–1VB10-63 Series Mini Circuit Breaker–1indicates the –C = O carbonyl stretching bond. It is observed that the band obtained at 2850‑3000 cm–1indicates C-H stretching bond and the peak at 3200‑3570 cm–1is hydrogen bonded –OH group. The FTIR spectra of PVA/Industrial Plastic Air Source Lockout–1as shown inPVC Wall Panel Made in China. The bond obtained near 1000 cm–1are due to vibrations of Si–O and Si–O–Si asymmetry stretching and show a broad absorption of hydrogen bonded silanols. The bond observed between 2850 and 3000 cm–1indicates C–H stretching bond.
