摘要: Multiwall carbon nano tube (MWCNT) was oxidized in the presence of mineral acid mixtures and further followed by conjugation with near infra red dye (NIR dye). Thus obtained NIR functionalized MWCNT characterized various analytical techniques. The application MWCNT-NIR system towards ring opening polymerization (ROP) e-Caprolactone (C.L) carried out bulk method at 140 °C under inert atmosphere aid stannous octoate (S.O) as a catalyst. ROP two different experimental conditions like variations [M0/I0] [C.L] order to find structure–property relationship. melting temperature (Tm) end capped poly(caprolactone) (PCL) increased increase values. binding constant (K) between PCL determined UV-visible spectroscopy.
