Enhanced Thermal Property and Flame Retardancy via Intramolecular 5-Membered Ring Hydrogen Bond-Forming Amide Functional Benzoxazine Resins

Polybenzoxazines containing an ortho-amide group in the backbone with a significant degree of aromaticity have been synthesized and characterized in this study. This class of materials makes use of smart chemistry to be able to readily process the monomer and later transform from polybenzoxazine into polybenzoxazole. All the benzoxazine monomers studied contain amide groups that form 5-membered intramolecular hydrogen bonds with the oxazine rings. Systematic manipulation of the diamine structure has allowed the structure property relationship of polybenzoxazines to be examined. Polymerization behavior of monomers is studied by differential scanning calorimetry (DSC) and in situ Fourier transform infrared spectroscopy (FT-IR). Thermal stability and flammability are characterized by thermogravimetric analysis (TGA) and microscale combustion calorimetry (MCC), respectively. The experimental results are fitted to the major thermal decomposition processes contributing to the specific heat release rate histories Q'(T). This family of materials show one of the lowest heat release capacity values of all polymers indicating the excellent flame retardancy.

Inorganic-Organic Hybrid Photomechanical Crystals Consisting of Diarylethenes and Cage Siloxanes

Photomechanical materials have received increasing attention because of their wide range of potential applications. This paper reports the design of photoresponsive inorganic-organic hybrid molecules consisting of diarylethene and polyhedral oligomeric silsesquioxane (POSS) linked by amide bonds. The POSS modification of diarylethene enhanced the conversion ratio from the open- to the closed-ring isomers upon UV irradiation in a solution. When isobutyl-substituted POSSs were introduced, hydrogen-bonded molecular crystals with a long needle-like morphology were obtained. Reversible photochromic responses and photoinduced macroscopic bending of these crystals upon ultraviolet (UV) and visible light (Vis) irradiations have been achieved. The high fatigue resistance of the diarylethene moiety combined with enhanced thermal stability endowed by the siloxane moiety is promising for practical applications in actuators and other smart devices.

Effects of unsaturated double bonds on adsorption and aggregation behaviors of amide-based cationic Gemini surfactants

Four cationic amide Gemini surfactants, containing unsaturated and saturated hydrophobic chains, were synthesized from oleamide propyl dimethylamine (PKO-18:1) and stearate amide propyl dimethylamine(PKO-18). The chemical structures of the synthesized compounds were characterized by FT-IR spectra and H-1 NMR. The Krafft temperatures were experimentally determined.. Their critical micelle concentration(CMC) in the aqueous solutions were determined by surface tension and conductivity methods. Equilibrium surface tension parameters such as gamma(cmc), pC(20), Gamma(max), A(min), Delta G degrees(mic)(Gibbs free energy of micellization), Delta G degrees(ads)(Gibbs free energy of adsorption) were obtained. Their adsorption behavior was analyzed through dynamic surface tension. Also, their self-assembly behaviors were investigated by negative-stained transmission electron microscopy(TEM) and critical packing parameter calculation. The results showed that the unsaturated double bond in hydrophobic chains was favorable for lowering the Krafft temperature and CMC. The oleamide-based Gemini surfactants present a lower Krafft temperature, higher surface activity and the adsorption kinetic process were conformed mixed diffusion-kinetic control model. The TEM results showed that the oleamide-based Gemini surfactants containing unsaturated double bonds in hydrophobic chains preferentially form worm-like micelles in solution. However, the stearate amide Gemini surfactants whose hydrophobic chains are saturated alkyl chains tend to form spherical aggregates in solution.

Novel strains with superior degrading efficiency for lincomycin manufacturing biowaste

As the antibiotic pollution source in the environment, a large amount of biowastes generated from antibiotic fermentation manufacture needs proper disposal. Recycling the biowaste as resources and nutrients is of great interest. Besides, degradation or removal of antibiotics is indispensable for the reclamation of antibiotic manufacturing biowaste. To establish environmentally friendly disposal strategies for lincomycin manufacturing biowaste (LMB), we screened the microbial strains that could efficiently degrade lincomycin from the antibiotic wastewater treatment plant. Among them, three novel strains were identified as Bacillus subtilis (strain LMB-A), Rhodotorula mucilaginosa (strain LMB-D) and Penicillium oxalicum (strain LMB-E), respectively. LMB-A and LMB-D could degrade 92.69% and 74.05% of lincomycin with an initial concentration of 1117.55 mg/L in 144 h, respectively. The lincomycin degradation products were formed by the breakage of amide bond or losing Ndemethyl/thiomethyl group from the pyrrolidine/pyranose ringcata cata catalyzed by the strains. Moreover, LMB-A could decontaminate LMB, and the decontaminated LMB could be used as a nitrogen source to culture salt-resistant bacteria and other useful microorganisms. LMB-A and LMB-D have the potential to be used for the bioremediation of water and soil polluted by lincomycin and its analogs. LMB-E could degrade 88.20% LMB after 144-h cultivation. In summary, this study gives an insight into the green disposal of LMB, and the established strategy has potential application for biotreatment of other antibiotic fermentation manufacturing biowastes.
