| 요약 | The work presented here focuses on utilization of kraft softwood lignin in phenol formaldehyde (PF) resins and phenolic foams. Enormous efforts have been carried out to find promising substitution of phenol and reduce the dependence of this indu |
| 요약 | This thesis is divided into four chapters. In Chapter 2, kraft lignin (KL) was applied to synthesize KL-based phenol formaldehyde resins at 25%, 38% and 50 wt.% substitution rates. Results showed that up to 25% of substitution rate can be achiev |
| 요약 | To further improve the shelf-life and wood failure performance of lignin-based PF resins, Chapter 3 studied the protocol parameters and optimized the protocol of resin preparation. The parameters investigated include the formaldehyde addition me |
| 요약 | Besides the incorporation of lignin in phenol formaldehyde resins, lignin-based phenolic foams have also been investigated in Chapter 4 and 5. In Chapter 4, both kraft lignin and phenolated lignin-based phenolic foams were prepared and character |
| 요약 | The effect of various parameters on the mechanical properties and thermal performances have been investigated in Chapter 5. Experimental designs were employed to study the formulation of KLPF and PLPF foam productions. With unmodified KL, only 1 |
| 요약 | Aimed at further understanding the factors that were related to the properties, fundamental studies were carried out in terms of the degree of crosslinking and pore sizes. Studies revealed the linear correlation between the degree of crosslinkin |
