“…The quality of chemical protective materials is generally judged by the breakthrough time [145][146][147][148][149]. This parameter describes the time from the beginning of the exposure until the chemical appears on the inside of the glove [148].…”

Recent advances in biopolymers, including functional biomaterials for the manufacture of personal protective garments (PPGs) or equipment (PPE) have dramatically improved their efficiency and performance. Good and acceptable permeation characteristics, mechanical strength and durability are common attributes of these materials simultaneously without compromise for their cost-effectiveness and manufacturability. The comprehensive characterization of these materials and specimens' three-dimensionality with the endeavor to obtain the highest resistance to highly toxic agents such as nuclear, chemical and biological warfare agents is the must fulfilling aim in today's global interest in continuous development in this area. Because energy absorption component seems to be important in considering quality the requirements related to the application of most protective materials (e.g. clothing), spectroscopy would seem to be the cornerstone to be considered for most analytical purposes to supplement the qualitative and quantitative assessment of polymeric materials. The major techniques worth mentioning include: scanning electron microscopy coupled to Xray dispersive spectroscopy (SEM/EDS), atomic force microscopy (AFM), scattering-type near-field optical microscopy, scanning tunneling microscopy (STM), attenuated total reflectance Fourier transform spectroscopy (ATR-FT-IR), infrared spectroscopic ellipsometry, nano-FTIR absorption spectroscopy, near-field optical microscopy, and infrared vibrational nano-spectrosocopy. This chapter will discuss the importance of a particularly important natural polymer (cellulose) containing acetyl groups to form modifiable biopolymers (e.g. cellulose acetate polymers), doped to yield multi-layered functional protective materials (MFPMs) or composites (MFPCs). The ultimate aim seeks to provide critical insights into understanding the enhancement of their permeation characteristics against exposure to toxic industrial chemicals, including chlorine which is currently being used as a chemical warfare agent of choice in the Syrian conflict. MFPMs or MFPCs are a group of materials made from a combination of fiber or polymers together with varying amounts of additives possessing tailored physical and mechanical properties. Many of these materials should not only be durable but also must provide cost-competi

Chemical-resistant gloves are used for protection from pesticides in farming operations. Cleanup of gloves after pesticide contamination was the focus of this research. Nitrile, neoprene, and barrier laminate glove specimens were exposed to 300 mg terbufos or tefluthrin granules for 3 or 30 min in petri dishes in a laboratory. Specimens were cleaned by flush with running water or LaunderOmeter washing with detergent. Following the cleanup treatments, specimens were dried and placed in test tubes with solvents to extract pesticide residue. Levels of contamination remaining were determined by gas chromatography. The residue remaining varied with exposure time, material type, cleanup method, and pesticide. Flush was more effective with the shorter exposure time. Tefluthrin was more effectively removed than terbufos. Barrier laminate was confirmed as a single-use material. Cleanup procedures reduced contamination in nitrile and neoprene, but findings show that these materials retained residue after cleanup.
