Title:
METHOD FOR DETERMINING A DELAY IN THE CRYSTALLISATION OF A THERMOPLASTIC POLYMER, USE OF SUCH A POLYMER FOR COATING OR ENCAPSULATING AN ELECTRONIC COMPONENT, AND ASSOCIATED METHOD
Document Type and Number:
WIPO Patent Application WO/2018/206897
Kind Code:
A3
Abstract:
The invention relates to a method for determining a delay in the crystallisation of a semi-crystalline thermoplastic polymer having a melting point Tf1. The method comprises: (a) a first step of heating the semi-crystalline thermoplastic polymer to a temperature T1, such that Tf1 < T1; (b) a step of cooling the semi-crystalline thermoplastic polymer obtained in step (a) from T1 to a temperature T2 , such that T2 < Tf1; (c) a second step of heating the semi-crystalline thermoplastic polymer obtained in step (b) from T2 to T1; and, optionally, (d) repeating, at least once, step (b) from T1 to a temperature T and step (c) from T to T1, with T2 ≤ T, the delay in the crystallisation of the polymer being observed as soon as DSC monitoring reveals the absence of a crystallisation peak during step(s) (b) and the absence of a melting peak during step(s) (c) at temperature TEF , such that T ≤ TEF ≤ Tf1. The invention also relates to the use of such a polymer for coating or encapsulating at least one (opto)electronic component, as well as to a method for coating or encapsulating such components. The invention further relates to an assembly obtained using said coating or encapsulation method, to a photovoltaic module comprising such an assembly, and to a method for producing such a module.
