材料奈米化Material Nanosizing

利用光學濺鍍與光學膜堆技術，整合第六代離子助鍍法，開發出高效奈米化及穩定萃取30奈米以下的材料製程，有效避免奈米材料分散時所產生的高斯分布曲線與材料共聚復歸現象，達到真正材料奈米化的精髓。

By combining optical sputtering and optical multilayer technology with sixth-generation ion-assisted deposition, STC has developed a process for efficient nanosizing and stable extraction of materials below 30 nanometers. The process is designed to avoid the Gaussian particle-size distribution and re-agglomeration associated with nanomaterial dispersion, achieving the essence of material nanosizing.

簡單說，就是讓固體材料表面的原子或分子從高能量粒子取得動能，以5～30奈米的粒徑大小從固體表面被擊出，讓奈米材料均勻佈植於另一個想運用的材料表面。例如奈米銀佈植於不織布上，可應用在空氣濾網、口罩等防疫相關產品；或將銀、氧化鋅、涼感材料等奈米材料佈植於薄膜上，提供更多產品應用可能性。

In simple terms, high-energy particles transfer kinetic energy to atoms or molecules on a solid surface, ejecting material with particle sizes of 5–30 nanometers. These nanomaterials are then uniformly deposited onto another material surface. For example, nanosilver deposited onto nonwoven fabric can be used in air filters, masks, and related protective products. Depositing nanomaterials such as silver, zinc oxide, or cooling materials onto films creates further possibilities for product applications.

STC機能性薄膜原材的應用Applications of STC Functional Film Materials

佈植奈米材料的薄膜可直接作為膜材使用。例如，含奈米銀的薄膜具有抗菌功效，可貼附於經常接觸且需要消毒的表面，如醫院櫃檯、門把及公共空間扶手，以減少清潔人員反覆清潔消毒的頻率。原文亦指出，一般常見清潔劑多為有機揮發性溶劑，容易經皮膚或呼吸道進入人體，過量累積可能危害健康。

Films incorporating nanomaterials can be used directly as functional film products. For example, nanosilver-containing films provide antibacterial functionality and can be applied to frequently touched surfaces requiring disinfection, such as hospital counters, door handles, and handrails in public spaces, to reduce repeated cleaning and disinfection. The original article also states that many common cleaning agents are volatile organic solvents that may enter the body through the skin or respiratory tract, and that excessive accumulation may pose health risks.

STC機能性薄膜原材經特殊製程處理。原文指出，其奈米材料溶出率遠低於美國FDA所訂定的容許值，為穩定的機能性材料，並宣稱不會經觸摸或空氣等媒介進入人體，安全無虞。

STC functional film materials undergo a specialized manufacturing process. The original article states that nanomaterial release is well below the permissible limits established by the U.S. FDA, describes the material as stable, and claims that it does not enter the human body through touch or airborne exposure and is safe.

氧化鋅抗菌材Zinc Oxide Antibacterial Materials

STC Nanotech獨家研發安鋅長效抗菌噴劑Anxin Long-Lasting Antibacterial Spray Developed by STC Nanotech

STC Nanotech獨家研發安鋅長效抗菌噴劑，內含30奈米粒徑氧化鋅抗菌材，經專業乳化技術讓奈米氧化鋅抗菌材均勻且穩定分散，在物體表面形成主動抗菌層。

Developed by STC Nanotech, Anxin Long-Lasting Antibacterial Spray contains zinc oxide antibacterial material with a particle size of 30 nanometers. Specialized emulsification technology enables uniform, stable dispersion of the nano zinc oxide to form an active antibacterial layer on object surfaces.

奈米氧化鋅與病菌外層細胞壁因正負電荷差異而相互吸引，並釋出正電離子，干擾病菌體內平衡及維生機能，進而抑制繁殖，達到主動抑菌，避免病菌孳生及發臭等問題。

Differences in electrical charge attract nano zinc oxide to the outer cell walls of microorganisms. The material releases positively charged ions that disrupt their internal balance and vital functions, inhibiting reproduction and helping prevent microbial growth and associated odors.

原文指出，經實驗證實，30奈米粒徑為長效抗菌最佳尺寸，無細胞毒性且可主動長效抗菌，可用於背包、衣物鞋子、桌面門把、生活用品、居家環境、衛浴空間及公共空間等。

The original article states that experimental results identify 30 nanometers as the optimal particle size for long-lasting antibacterial performance, with no cytotoxicity and active, sustained antibacterial effects. Listed applications include backpacks, clothing, shoes, tabletops, door handles, everyday items, home environments, bathrooms, and public spaces.

原文將奈米氧化鋅描述為溫和、不刺激的抗菌材料，並指出鋅是自然界及人體生長所需的重要元素，適量攝入不影響自然循環與代謝，相較其他抗菌材料對環境與人體較友善。原文亦列舉氧化鋅於醫學及日常用品的應用，包括嬰兒爽身粉、膠布、抗菌軟膏、防曬油及乳霜乳液，並宣稱其具有溫和、不刺激、不過敏的特性。

The original article describes nano zinc oxide as a mild, non-irritating antibacterial material and notes that zinc is an important element in nature and human growth. It states that intake in appropriate amounts does not affect natural cycles or metabolism and describes the material as comparatively friendly to people and the environment. It also lists uses of zinc oxide in medical and everyday products, including baby powder, adhesive dressings, antibacterial ointments, sunscreen, creams, and lotions, and claims mild, non-irritating, non-allergenic properties.

機能性塑膠母粒Functional Plastic Masterbatches

STC機能性薄膜原材可透過二次造粒技術製成機能性母粒，再抽紗應用於紡織業，例如機能性涼感衣、膠原蛋白紗線、竹炭紗線及奈米銀纖維布。不同奈米材料可提供不同功能，例如涼感快乾、抑菌除臭及遠紅外線等。

STC functional film materials can be converted into functional masterbatches through secondary pelletization and subsequently spun into fibers for textile applications. Examples include cooling apparel, collagen yarn, bamboo charcoal yarn, and nanosilver fiber fabrics. Different nanomaterials provide different functions, such as cooling and quick drying, antibacterial and deodorizing performance, and far-infrared functionality.

機能性塑膠母粒亦可透過射出成型製程，應用於醫療抗菌、工業觸媒、機能性民生用品及軍工產業等領域。

Functional plastic masterbatches can also be processed through injection molding for applications in medical antibacterial products, industrial catalysts, functional consumer goods, and defense-related industries.

輻射散熱Radiative Heat Dissipation

太空環境中複合式光學膜堆散熱技術的核心概念與重要原則Core Concepts and Key Principles of Composite Optical Multilayer Heat Dissipation in Space

複合式光學膜堆散熱技術在太空環境中的核心概念，是透過多層薄膜結構的精確光學設計，實現對熱輻射頻譜與方向的主動調控。不同於地面散熱依賴對流或液冷，在幾乎真空的太空環境中，系統熱能僅能透過熱傳導與熱輻射兩種機制傳遞。

The core concept of composite optical multilayer heat dissipation in space is to control the spectrum and direction of thermal radiation through precise optical design of multilayer thin-film structures. Unlike terrestrial cooling that relies on convection or liquid cooling, heat in the near-vacuum environment of space is transferred only through conduction and thermal radiation.

因此，複合式光學膜堆的核心本質，是將材料表面打造為一種「光學天線」，在特定紅外波段，主要為8–14 μm大氣窗口，達到接近黑體的高發射率，同時在太陽光波段（0.3–2.5 μm）維持極低吸收率，從而在不消耗額外能量的情況下，高效向外太空輻射熱量。

The multilayer structure therefore turns the material surface into an “optical antenna,” achieving high emissivity approaching that of a blackbody in selected infrared wavelengths, primarily the 8–14 μm atmospheric window, while maintaining very low absorptivity across the solar spectrum of 0.3–2.5 μm. This enables efficient radiation of heat into outer space without additional energy consumption.
