Overview - The new materials industry in China is transitioning from self-sufficiency in low-end products to independent research and development of mid-to-high-end products, currently positioned in the second tier globally, with a total output value of 5.3 trillion yuan in 2020, a 15% increase from the previous year, and expected to reach 10 trillion yuan by 2025, with a compound annual growth rate of approximately 13.5% [4][10][11]. New Material Directions Lightweight Materials - Carbon fiber is recognized as the most widely used and market-oriented material in the new materials sector, with China becoming the second-largest producer globally. However, challenges remain in production capacity utilization and high-end product development, leading to significant reliance on imported carbon fiber [28][29]. Aerospace Materials - Polyimide and silicon carbide fibers are highlighted as key materials in the aerospace sector, with increasing demand driven by advancements in aerospace technology [3]. Semiconductor Materials - Silicon wafers, silicon carbide (SiC), and high-purity metal sputtering targets are essential for the semiconductor industry, which is critical for technological advancement and self-sufficiency [3]. New Plastics - New types of plastics such as polyamide (PA), polyphenylene sulfide (PPS), and polylactic acid (PLA) are being developed to meet the growing demand in various applications [3]. Electronic and Electrical Capacitor Materials - Electronic pastes, electronic ceramics, and polybutylene terephthalate (PBT) are crucial for the electronics industry, reflecting the need for advanced materials in electronic applications [3]. Multi-purpose New Materials - Materials like polyphenylene oxide (PPO), para-aramid fibers, and superabsorbent polymers (SAP) are being explored for their versatility across different industries [3]. Optical and Electronic Chemicals - Optical films, photoresists, and OLED materials are essential for the electronics and display industries, indicating a shift towards high-performance materials [3]. Conclusion and Recommendations - The "14th Five-Year Plan" emphasizes the strategic importance of the new materials industry, aiming for high-quality development and increased self-sufficiency. The plan addresses the need for stronger innovation and collaboration within the industry to enhance competitiveness on a global scale [20][22][23].
