Abstract

The paper presents research results on the crystallization kinetics of polycaprolactone (PCL) with micro- and nano-additives such as talc (nucleation agent) and nanosilver (antibacterial agent). The process of isothermal crystallization was studied in a narrow temperature range 38.5—41.5 °C using Differential Scanning Calorimetry (DSC) and Thermooptical Analysis (TOA) methods. The kinetics of the process are described using the Avrami model. The parameters n and log K of the equation were calculated. Changes in the half time of crystallization, degree of crystallinity and melting temperature of the polymer under the influence of the fillers and the conditions of crystallization were analyzed.
