In addition, FTIR spectrum of PVA nanofiber is shown inMetal Fittings for Pipe and Joint System (H-6A). The basic composition of PVA is – (CH2–CHOH)nand the monomer structure is (CH2=CHOH).Stable and High Precision CNC Milling Machinery Toolclearly reveals the major peaks associated with PVA. The peak observed at approximately 1100 cm–13A Under Floor Heating Room Thermostat–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.
