Thermal Properties of Manganese Chloride Salt Reinforced [PVA: PVP] Blend Films

The casting process was used to make pure [PVA: PVP] polymer blend film and MnCl2.4H2O salt augmented polymer blend film at varied weight ratios ((10, 20, 30, 40, 50) wt. percent). The influence of salt weight ratio on the thermal characteristics of [PVA: PVP] polymer blend films augmented with MnCl2.4H2O salt was also investigated. The coefficient of thermal conductivity of the [PVA: PVP] polymer blend films reinforced by MnCl2.4H2O was found to be higher in the experimental results. As the weight ratio of MnCl2. 4H2O grows and then falls, the MnCl2.4H2O salt increases and then reduces erratically. As the concentration of MnCl2.4H2O salt rises, it is discovered that the thermal conductivity coefficient of whole polymer mix films is extremely low. As a result, such films could be utilized as heat-insulation shields. The temperature of glass transition and crystal melting temperature of [PVA: PVP] polymer blend films reinforced by MnCl2.4H2O salt change as the weight ratio of MnCl2.4H2O salt increases.
