Hydrogels in drug delivery: progress and challenges

Carbon nanotubes (CNTs) hold the promise of delivering exceptional mechanical properties and multi-functional characteristics. Ever-increasing interest in applying CNTs in many different fields has led to continued efforts to develop dispersion and functionalization techniques. To employ CNTs as effective reinforcement in polymer nanocomposites, proper dispersion and appropriate interfacial adhesion between the CNTs and polymer matrix have to be guaranteed. This paper reviews the current understanding of CNTs and CNT/polymer nanocomposites with two particular topics: (i) the principles and techniques for CNT dispersion and functionalization and (ii) the effects of CNT dispersion and functionalization on the properties of CNT/polymer nanocomposites. The fabrication techniques and potential applications of CNT/polymer nanocomposites are also highlighted.

Dispersion and functionalization of carbon nanotubes for polymer-based nanocomposites: a review

Nucleation, structure and lamellar morphology of isotactic polypropylene filled with polypropylene-grafted multiwalled carbon nanotubes

P4VPy(DBSA)x complexes (x = 0.25, 0.50, 0.75, or 1.00 DBSA/P4VPy repeat units) are able to form inclusion complexes with three cyclodextrins (CDs). The complexes were characterized by XRD, XPS, 13C CP/MAS NMR, 1H NMR, DSC, and TGA. A columnar structure with poor order is established in all the inclusion complexes. XPS studies show that the interaction between DBSA and P4VPy is affected by inclusion complexation when the DBSA content is high (x ≥ 0.5), resulting in the expulsion of some DBSA ions from the polymer chain and reprotonation. TGA shows that the initial decomposition temperatures of the inclusion complexes are lower than those of the CDs and the pristine complexes, a result different from that of the linear chain polymer−cyclodextrin ICs. DSC measurements indicate that the inclusion of the side chains within CDs makes the P4VPy main chain much stiffer, thereby raising the glass transition temperature. 1H NMR measurements also suggest that interactions between CDs and the side chains of P4VPy(DBS...

Inclusion Complexes of Poly(4-vinylpyridine)−Dodecylbenezenesulfonic Acid Complex and Cyclodextrins

Poly(neopentyl glycol sebacate) (PNGS) is able to form inclusion complexes with three cyclodextrins (α-CD, β-CD, and γ-CD). The complexes are characterized by XRD, 13C CP/MAS NMR, FTIR, 1H NMR, and...

Crystallization and dynamic mechanical behavior of double-C60-end-capped poly(ethylene oxide)/multi-walled carbon nanotube composites

Polymer complexes of a basic polymer, poly(N-methyl-4-piperidinyl methacrylate) (PMPMA), with a weak acidic polymer poly(p-vinylphenol) (PVPh), and strong acidic polymers such as poly(acrylic acid) (PAA), poly(methacrylic acid) (PMAA), poly(styrenesulfonic acid) (PSSA), and poly(vinylphosphonic acid) (PVPA), have been prepared by mixing ethanol/H2O (1:1) solutions of the respective components. The complexes were examined by Fourier transform infrared (FTIR) spectroscopy, X-ray photoelectron spectroscopy (XPS), and differential scanning calorimetry. Both the FTIR and XPS studies showed the existence of piperidinium ions in the complexes of PMPMA with PAA, PMAA, PVPA, and PSSA, indicating that the interactions in these complexes are ionic in nature. However, the N-methyl groups prevent the piperidine nitrogen atoms from interaction with PVPh and hence the carbonyl groups of PMPMA interact with the hydroxyl groups of PVPh by hydrogen bonding. From the XPS studies, the number of protonated piperidine atoms wa...
