Malaria is still a major tropical disease, with Africa particularly burdened. It has been proposed that outdoor protection could aid substantially in reducing the malaria incidence rate in rural African communities. Recently, melt-spun polyolefin fibers containing mosquito repellents have been shown to be promising materials to this end. In this study, the incorporation of N,N‑Diethyl‑3 ...

Abstract The manuscript details the first literature example of fibers of poly( l -lactic acid) (PLLA) containing a mosquito repellent agent, N,N-diethyl-3-methylbenzamide (DEET). The fibers were prepared by electrospinning, are defect-free and have uniform diameter of the order of magnitude of 1 µm. Thermogravimetry and infrared spectroscopy showed that it is possible to incorporate more ...

Answer 1 of 13: I was told by the nurse at Riu Palace Tropical Bay Negril , that only a repellent containing DEET will keep sand fleas from biting. I have never been bit in over 30 years going here till this year. I did have lotion but did not use it till after...
Jul 01, 2019·The plasticizing effect of N,N-diethyl-3-methylbenzamide (DEET) on poly(l-lactic acid) (PLLA) is analyzed and discussed in this manuscript.DEET is the key active ingredient in many commercial mosquito-repellent formulations, and is also an environment-friendly compound, which well matches the biodegradability and compostability of PLLA.
The fibers showed the sustained release of vancomycin. CyD-functional polymeric nanofibers were also used to the delivery of a common insect repellent, N, N-diethyl-3-toluamide (DEET) . Micro-sized fibers with a diameter of 2.8 ± 0.8 μm were obtained by the electrospinning of a water-soluble β-CyD/pyromellitic dianhydride (PMDA) polymer and ...

2015-01-01. The recycling of waste polyurethane ( PU) using radiation-induced grafting was investigated. The grafting of waste PU onto a high-density polyethylene (HDPE) matrix was carried out using a radiation technique with maleic anhydride (MAH). HDPE pellets and PU powders were immersed in a MAH-acetone solution.
