An excellent calibration was developed using the same cast film technique and IR peaks as the ASTM D3900 PE/ PP copolymer method. WebTEM results. From Figure 2, as the stirring time of reaction increased, the intensity of the SPR peak also showed a gradual increment until 24 h but after 48 h the SPR peak changed to a broad shape and intensity decreased,. This phenomenon is related to the increased size and also agglomeration of silver nano-crystals [31].
