一般描述

三甲氧基(十八烷基)硅烷（OTS）是一种重要的烷基硅烷，可与氧化硅形成强共价键，并可作为微机电系统（MEMS）的潜在润滑剂。OTS主要用于表面化学改性，[1]对二氧化硅进行改性可使各种真空沉积和溶液浇铸有机半导体的电荷载流子迁移率增加。
三甲氧基（十八烷基）硅烷（OTMS）是一种烷基硅烷，可官能化多种纳米颗粒表面并促进形成具有高水接触角和低表面能的疏水涂层。[2][3]

应用

OTS用于开发自组装单分子层（SAM）。[1]OTS还用于对有机场效应晶体管的二氧化硅电介质表面进行改性。
磁性纳米粒子（Fe2O3）可以使用OTMS进行表面修饰。它可形成一种吸附剂，用于从牛奶样品中对内分泌干扰物（有机氯农药）进行磁性固相萃取（MSPE）。[4]它可在AZ31镁合金上形成防腐蚀涂层，从而在汽车工业中具有潜在应用。[5]它也可用于与粉煤灰形成复合材料，并用作涂层以形成超疏水和防紫外线的棉织物。[6]

A series of octadecylsilane-modified silicas were prepared by sol-gel and grafting methods. Carbon contents and octadecyl chain conformations were shown to depend on the preparative route. Grafting engenders a low carbon content and a liquid-like chain conformation, while the sol-gel

Both self-healable conductors and stretchable conductors have been previously reported. However, it is still difficult to simultaneously achieve high stretchability, high conductivity, and self-healability. Here, we observed an intriguing phenomenon, termed "electrical self-boosting", which enables reconstructing of electrically percolative pathways

Hydrophobic gold nanorods were fabricated from hydrophilic gold nanorods coated with hexadecyltrimethylammonium bromide by treating with mercaptopropyltrimethoxysilane (MPS) and subsequently octadecyltrimethoxysilane (ODS). The fabrication of the hydrophobic shell went through the process of (1) binding MPS onto the nanorods, (2)

Questions

1–2 of 2 Questions  

  1. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 answer

    1. Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf

  2. How can I determine the shelf life / expiration / retest date of this product?

    1 answer

    1. If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
      For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
      For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.
      For more information, please refer to the Product Dating Information document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/449/386/product-dating-information-mk.pdf
