Q3、公司调光导电膜主要采用哪种技术路线，优点缺点如何？ 答：目前市场主流的调光膜技术分为 PDLC（聚合物分散液晶）、 SPD（悬浮粒子）、LC（染料液晶）和 EC（电致变色）四种。公 司开发的调光导电膜系列产品覆盖了前述的这四种主流技术，目 前在售的产品以 EC 为主，应用于汽车天幕、侧窗、后视镜等场景。 优缺点来看，EC 电致变色路线优点在于低电压，耗电少，断电情 况下仍然能保持原色，变色倍率、雾度性能都较优，缺点在于变 色速度相较于其他路线慢。PDCL 以及 PDCLC 路线的优点在于变色 快，但是雾度偏高，从公司导电材料的角度看，对方阻要求不高， 技术壁垒相对较低。SPD 最主要是工作电压高，耗电且雾度也偏 高。 证券代码：003015 证券简称：日久光电 江苏日久光电股份有限公司投资者关系活动记录表 编号：2025-009 | ☑ | 特定对象调研 □分析师会议 | | --- | --- | | 投资者关系活动类 | □媒体采访 □业绩说明会 | | 别 | □新闻发布会 □路演活动 | | | □现场参观 | | | □其他 （请文字说明其他活动内容） | | 活动参与人员 | 宁银理财 高晗 ...

Investment Rating - The report maintains an "A" rating for the new materials industry, indicating a positive outlook for the sector [1]. Core Insights - The chemical raw materials sector is currently experiencing a bottoming phase, with a slowdown in capacity expansion and a potential alleviation of intense competition and price wars. The overall profit margin for the industry is expected to remain between 3% and 5% in 2024, which is at a historical low. However, with the central economic work conference emphasizing the need to address "involution" competition, there is potential for improved industry order and profit recovery [1][34]. Summary by Sections 1. Market Performance and Valuation - The new materials index has shown significant volatility, underperforming the Shanghai Composite Index by 10.6% as of December 27, 2024. The index's performance was particularly weak in the first three quarters of 2024 but saw a recovery in the fourth quarter due to favorable policies [15][20]. 2. Focus Areas 2.1 Supply and Demand Dynamics - The vitamin sector is expected to maintain high prices for Vitamin E due to limited supply recovery from BASF's production facilities, which are aging and unable to meet demand. The report suggests monitoring companies like New Hope Liuhe and Zhejiang Medicine [42][59]. - The renewable energy materials sector is projected to benefit from a stable increase in wind power demand, with a significant rise in installed capacity and a self-regulatory agreement among wind turbine manufacturers to mitigate price competition. Companies like Times New Material and Mega Chip Color are highlighted for investment [44][60]. 2.2 Emerging Industry Opportunities - The bio-manufacturing sector is positioned for growth, particularly in synthetic biology and sustainable aviation fuel (SAF). The report emphasizes the importance of product selection and platform capabilities for companies in this space, recommending firms like Huaheng Biological and Meihua Biological [48][50]. - The special coatings market is expected to grow due to increasing military expenditures and the need for stealth materials. Companies such as Huaqin Technology and Jiachih Technology are noted for their potential in this area [52][61]. - The semiconductor materials sector is anticipated to benefit from the recovery of consumer electronics and AI applications, with a focus on domestic production capabilities. Companies like Stik and Aisen are recommended for investment [56][61]. - The humanoid robotics market is projected to drive demand for PEEK materials, with domestic companies expected to gain market share due to cost advantages. The report suggests monitoring firms like Zhongxin Fluorine Materials and Zhongyan Co. [58][61].
