| dc.description.abstract | The work carried out in this thesis describes a facile technique to develop a novel self-healing coating with the goal of producing autonomous intrinsic self-heal ing fabrics that can recover from damage at room temperature without the use of ex ternal stimuli. The self-healing coating was developed using high ammonia natural rubber latex (HANRL) consisting dynamic reversible metal thiolate ionic network. The work carried out in this thesis started with fabrication and characterization of self healing HANRL films. The effect of zinc thiolate (ZT) (0, 15, 30, 45 phr) contents which is responsible for formation of reversible ionic network within the HANRL was investigated. Formation of reversible ionic network was evidenced by Differential Scanning Calorimetry (DSC), Ultraviolet-visible spectroscopy (UV-vis), Fourier Transform Infrared (FTIR) and zeta potential. The mechanical performance results re vealed that optimum self-healing of the HANRL was achieved at 30 phr of ZT. Sub sequently, impregnation of the selected self-healing HANRL formulation on synthetic polypropylene (PP) during coating was assessed by varying number of coating (single, double, triple, quadruple) layers on fabrics. The morphological showed that HANRL was successfully impregnated into the fabric and filled the gaps between the fiber. In general, the mechanical properties of the fabric improved 130% for single coated fab ric compared to the neat fabric. Moreover, fabric with single coating layer has good breathability and fabric to rubber adhesion. The feasibility of the developed self-heal ing HNRL coating was also investigate on various types of fabrics. The results showed that majority of the fabrics were successfully healed at room temperature | |
