Preparation and Morphology Study of Biodegradable Chitosan/Methoxy Poly(ethylene glycol)-b-Poly(ϵ-caprolactone) Nanocomposite Films

Preparation and characterization of biodegradable chitosan and methoxy poly(ethylene glycol)‐b‐poly (ε‐caprolactone) blend homogeneous films

“…This could be hypothesized that the hydrophobic component of MPEG-b-PCL was assembled and microscopically phase separated from hydrophilic chitosan during the drying process. 25,26 The results may be discussed from the FTIR spectra in Figure 2. The free amino band of the chitosan film bonds between the chitosan and the MPEG-b-PCL were slightly decreased.…”

Preparation of nanocomposite chitosan/silk fibroin blend films containing nanopore structures

“…5), which suggested that the nanocomposite blend films contained nanoporous structures. The nanopores in CS and SF nanocomposite films were formed due to self-condensation and phase separation of the nanoparticles (Baimark et al, 2007a;Srisuwan et al, 2008). However, the nanopore sizes of the nanocomposite CS/SF blend films were larger than both CS and SF nanocomposite films (Fig.…”

“…The nanoporous CS films have been prepared for use as metal absorbent (Liu, Tang, Chen, & Xin, 2005). In previous works (Baimark, Niamsa, Morakot, Threeprom, & Srisuwan, 2007a;Khamhan, Baimark, Chaichanadee, Phinyocheep, & Kittipoom, 2008), nanocomposite CS films loading with nanoparticles of methoxy poly(ethylene glycol)-b-poly(e-caprolactone) (MPEGb-PCL) have been reported. The nanoparticles dispersed throughout the CS film matrices enhanced water vapor sensitivity due to a hydrophobic character of MPEG-b-PCL nanoparticles.…”

Preparation, Properties and Applications of Chitosan-Based Biocomposites/Blend Materials: A Review

“…This strategy suggests that the hydrophobicity of PCL makes it possible to produce a blended material with good bio-compatibility [236], full bio-degradability [237,238], adequate mechanical strength [239,240] and one that is available for bio-functions [241]. The PCL/Cs blend was prepared by cast solution technique [242][243][244], electro-spinning [241] and semi-interpenetrating polymer networks [245]. It was found that, at the weight ratio of 80:20 (Cs: PCL) the result showed an increased percentage of elongation by 20.56% as compared to pure Cs film.…”
