“…The C-H stretch vibration of PACl backbone was detected at 2,925 cm −1 as a broad and weak absorption peak, while the 1,759 and 1,803 cm −1 peaks were originated from characteristic C=O stretching vibration of ester and acyl chloride respectively [14,15]. The FTIR feature in Figure 4c suggested that the PACl was attached to the surface of MWCNTs.…”

A facile approach was developed to prepare multi-walled carbon nanotubes/graphene nanoplatelets hybrid materials through covalent bond formation. First, poly(acryloyl chloride) was grafted onto oxidized multi-walled carbon nanotubes through the reaction between the acyl chloride groups of poly and the hydroxyl groups of oxidized multi-walled carbon nanotubes. Second, the remaining acyl chloride groups of poly were allowed to react with the hydroxyl groups of hydroxylated graphene nanoplatelets. Scanning electron microscopy and transmission electron microscopy data showed that the multi-walled carbon nanotubes and graphene nanoplatelets were effectively connected with each other. And Fourier transform infrared spectroscopy data indicated the formation of covalent bonds between carbon nanotubes and graphene nanoplatelets. Conformational changes were monitored by Raman spectroscopy. This novel kind of carbon hybrid materials may have the potential application in a wide field, especially in increasing the toughness and strength of the matrix resin.

“…It serves as an important building block for further functionalization and an excellent substrate for cross-metathesis in various polymerization, biological, and medical applications. [1][2][3][4] The fission of the C−Cl bond of CH 2 CHC(O)Cl produces Cl atom and C 2 H 3 CO radical, a crucial intermediate that has been proposed in reactions between O atom and propargyl (C 3 H 3 ) radical in combustion and atmospheric chemistry. 5 Extensive experimental investigations on CH 2 CHC(O)Cl have been conducted.…”

Irradiation at 193 nm of a p-H2 matrix containing acryloyl chloride CH2CHC(O)Cl at 3.2 K yielded infrared absorption lines at 3143.6 (ν1), 3057.0 (ν2), 3048.0 (ν3), 2103.1 (ν4), 1461.0 (ν5), 1349.8 (ν6), 1223.7 (ν11+ν12 or 2ν12), 1092.8 (ν8), 918.1 (ν9), 691.0 (ν10), 624.3 (ν11), and 597.1 (ν12) cm(-1) that are assigned to the 3-propenonyl (·CH2CHCO) radical. The assignments are based on the photolytic behavior and a comparison of observed vibrational wavenumbers and infrared intensities with those predicted with the B3PW91/aug-cc-pVDZ method. The observation is consistent with a major radical formation channel CH2CHCO + Cl followed by escape of the Cl atom from the original p-H2 cage. The observation of 3-propenonyl (·CH2CHCO) radical but not 3-propenalyl (s-cis- or s-trans-CH2CHĊO) radical indicates that the former is the most stable isomer and that the barrier heights for conversion from s-cis- or s-trans-CH2CHĊO to ·CH2CHCO are small.

“…After functionalization with PACl, the new peaks appeared in the spectrum of PACl‐grafted MWNT, compared with acid‐treated MWNT. The broad peak at 2925 cm −1 was assigned to CH stretch vibration of polymer backbone, and the peaks at 1803 and 1756 cm −1 originated from CO stretch vibration of acyl chloride 26. Since the PACl‐grafted MWNTs samples were repeatedly washed with THF, the IR features suggested that PACl was covalently attached to the surface of MWNT instead of physically absorbing 20…”

Multiwall carbon nanotube (MWNT) was grafted with polyacrylate‐g‐poly (ethylene glycol) via the following two steps. First, hydroxyl groups on the surface of acid‐treated MWNT reacted with linear poly(acryloyl chloride) to generate graft on MWNT; secondly, the remaining acryloyl chloride groups were subjected to esterification with poly(ethylene glycol) leading the grafted chains on the surface of MWNTs. Thus obtained grafted MWNT was characterized using Fourier transform infrared spectrometer, transmission electron microscopy, and X‐ray photoelectron spectroscopy. Thermogravimetric analysis showed that the weight fraction of grafted polymers amounted to 80% of the modified MWNT. © 2006 Wiley Periodicals, Inc. J Polym Sci Part A: Polym Chem 44: 6880–6887, 2006
