“…Thereby reducing the still air content inside the fabric, making the heat transfer capacity of the fabric rise. 57 Another one is that the thermal conductivity of the parylene C (0.082 W/m·K) 58 is much higher than Meftex10s (0.035 W/m·K), which causes the parylene C coated samples to perform higher thermal conductivity than the original ones. Besides, their thermal resistances are 0.0012, 0.00086, 0.00088, and 0.00098 K·m 2 /W, respectively.…”

This paper investigated the washability and comfort properties of a kind of electromagnetic interference shielding material (Meftex10) with and without the parylene C coating. Parylene C can form a uniform protective film on the fabric and improve different properties of the fabric. In this paper, it will be used to improve the washability of electromagnetic interference shielding material. Through a large number of experiments, it can be determined that the parylene C coated samples have a significant improvement in washability compared to the uncoated samples. When the sample’s parylene C coating content arrives at 33.4 g/m², its electromagnetic shielding effectiveness still remains around 65% after 10 times washing cycles. Conversely, as the content of the parylene C coating increases, the air permeability of the samples as well as the water vapor permeability will decrease. The reason is that the parylene C coating closes some of the pores, which affects air and water vapor transport through the material. In addition to this, it can be concluded that the thermal conductivities of samples increase with increasing parylene C coating contents. The above phenomenon is caused by the following two aspects: The parylene C coating material will reduce the spaces between the fibers and yarns by partially filling the pores, leading to less still air inside and the fabric has a greater capacity for heat transfer; Parylene C has a higher thermal conductivity than the electromagnetic interference shielding material (Meftex10).

“…The poly-para-xylylene-based polymer has very low thermal conductivity [38]. The thermal conductivity of parylene coating is dependent on the coating thickness, as was shown for Parylene C [39]. Parylene C is also used as a coating of silk fabric to protect it against exposure to daylight and ultraviolet light, which cause the aging of the material [40].…”

The article concerns research on using Parylene C coating on basalt fabric-based composites with potential use in protective clothing to improve their insulation against contact heat and radiant heat, as well as the sensory comfort of the user. The outcomes of the contact heat method showed that applying Parylene C coating improved the thermal insulation of all tested composites. Two of them achieved the first efficiency level of protection. The results of the radiant heat method presented that using the Parylene C coating did not cause changes in the thermal insulation against heat radiation of all tested materials; the radiant heat transfer index reached values in the range of 12.4 - 12.9 s. X-ray tomography (micro-CT) allowed for identifying breaks/snaps in basalt fibers irritating the user’s skin in direct contact with the composite. Micro-CT results also showed that using Parylene C coating eliminated the effect of skin irritation and increased the usability of basalt fabrics in clothing.

“…This method was initially developed for measuring the thermal conductivity of bulk materials and has been subsequently adapted for nanofluids and thin films. 94 It involves the application of sinusoidal current with a frequency ω across the sample using a metal wire heater which is similar to the hot wire method, where the sample element serves as both the heater and the thermometer. The applied current at frequency ω generates heat at a frequency of 2 − ω , and the corresponding voltage is measured at 3 − ω .…”
